CMC Overview
Installing and Setting Up the CMC This section provides information about how to install your CMC hardware, establish access to the CMC, and configure your management environment to use the CMC.
You can install a second CMC to run as a standby to the primary CMC. For more information about a standby CMC, see "Understanding the Redundant CMC Environment" on page 51. Installing Remote Access Software on a Management Station You can access the CMC using the Telnet, Secure Shell (SSH), or serial console utilities provided on your operating system or using the Web interface. If you want to use remote RACADM from your management station, you will need to install it.
2 If necessary, mount the Dell Systems Management Consoles CD using the following command or a similar command: mount /media/cdrom 3 Navigate to the /linux/rac directory and execute the following command: rpm -ivh *.rpm For help with the RACADM command, type racadm help after issuing the previous commands. For more information about RACADM, see "Using the RACADM Command Line Interface" on page 65.
Your CMC and the management station where you use your browser must be on the same network, which is called the management network. Depending on your security requirements, the management network can be an isolated, highly secure network. You must ensure that security measures on the management network, such as firewalls and proxy servers, do not prevent your Web browser from accessing the CMC.
3 Click Settings…. 4 In the No Proxy for field, add the addresses for CMCs and iDRACs on the management network to the comma-separated list. You can use DNS names and wildcards in your entries. Microsoft® Phishing Filter If the Microsoft Phishing Filter is enabled in Internet Explorer 7 on your management system and your CMC does not have Internet access, you may experience delays of several seconds when accessing the CMC, whether you are using the browser or another interface such as remote RACADM.
Downloading Files From CMC With Internet Explorer When you use Internet Explorer to download files from the CMC you may experience problems when the Do not save encrypted pages to disk option is not enabled. Follow these steps to enable the Do not save encrypted pages to disk option: 1 Start Internet Explorer. 2 Click Tools→ Internet Options…, then click Advanced. 3 Scroll to the Security section and check Do not save encrypted pages to disk.
chassis are connected in series and only one is connected to the management network. The basic connection type uses more ports on the management network and provides greater redundancy. The daisy-chain connection type uses fewer ports on the management network but introduces dependencies between CMCs, reducing the redundancy of the system. Basic CMC Network Connection For the highest degree of redundancy, connect each CMC to your management network.
Figure 2-1.
Follow these steps to daisy-chain up to four chassis: 1 Connect the GB1 port of the primary CMC in the first chassis to the management network. 2 Connect the GB1 port of the primary CMC in the second chassis to the GB2 port of the primary CMC in the first chassis. 3 If you have a third chassis, connect the GB1 port of its primary CMC to the GB2 port of the primary CMC in the second chassis. 4 If you have a fourth chassis, connect the GB1 port of its primary CMC to the GB2 port of the third chassis.
• Remote RACADM • The CMC Web interface Configuring Networking Using the LCD Configuration Wizard NOTE: The option to configure the server using the LCD Configuration Wizard is only available until the CMC is deployed or the default password is changed. Once the CMC is accessible from the network, the LCD panel cannot be used to reconfigure the CMC. The LCD is located on the bottom left corner on the front of the chassis. Figure 2-2 illustrates the LCD panel. Figure 2-2.
The LCD screen displays menus, icons, pictures, and messages. A status indicator LED on the LCD panel provides an indication of the overall health of the chassis and its components. • Solid blue indicates good health. • Blinking amber indicates that at least one component has a fault condition. • Blinking blue is an ID signal, used to identify one chassis in a group of chassis.
4 Select your network speed (10Mbps, 100Mbps, 1Gbps, or Auto) using the down arrow button. NOTE: The Network Speed setting must match your network configuration for effective network throughput. Setting the Network Speed lower than the speed of your network configuration increases bandwidth consumption and slows network communication. Determine whether your network supports the above network speeds and set it accordingly.
Static You manually enter the IP address, gateway, and subnet mask in the screens immediately following. If you have selected the Static option, press the center button to continue to the next CMC Network Settings screen, then: a Set the Static IP Address by using the right or left arrow keys to move between positions, and the up and down arrow keys to select a number for each position. When you have finished setting the Static IP Address, press the center button to continue.
NOTE: You cannot set a static IP address for the iDRAC using the LCD Configuration Wizard. To set a static IP address, use the CMC Web interface or RACADM. When you have made your selection, press the center button. The IP Summary screen displays, listing the IP addresses you provided. 9 On the IP Summary screen, review for accuracy the IP addresses you provided. To correct a setting, use the left arrow key to return to the screen for that setting. After making a correction, press the center button.
Table 2-1 describes each CMC network interface. Table 2-1. CMC Interfaces Interface Description Web interface Provides remote access to the CMC using a graphical user interface. The Web interface is built into the CMC firmware and is accessed through the NIC interface from a supported Web browser on the management station. For a list of supported Web browsers, see "Supported Web Browsers" on page 27.
To access the CMC interface using Dell Server Administrator, launch Server Administrator on your management station. From the system tree on the left pane of the Server Administrator home page, click System→ Main System Chassis→ Remote Access Controller. For more information, see your Dell Server Administrator User’s Guide. To access the CMC command line using Telnet or SSH, see "Configuring CMC to Use Command Line Consoles" on page 53.
You can use the RACADM getsysinfo command (see "getsysinfo" on page 298) or the Chassis Summary page (see "Viewing the Current Firmware Versions" on page 137) to view the current firmware versions for the CMCs installed in your chassis. If you have a standby CMC, it is recommended that you update the firmware in the standby CMC first. When the standby CMC has been updated, swap the CMCs’ roles so that the newly updated CMC becomes the primary CMC and the CMC with the older firmware becomes the standby.
Configuring Power Budgeting The CMC offers a power budgeting service that allows you to configure power budget, redundancy, and dynamic power for the chassis. The chassis ships with either three or six power supply units (PSUs). If your chassis has only three PSUs, you can add up to three more. The power management service enables optimization of power consumption and reallocation of power to different modules based on demand.
Adding SNMP and E-mail Alerts You can configure the CMC to generate SNMP and/or e-mail alerts when certain chassis events occur. For more information, see "Configuring SNMP Alerts" on page 238 and "Configuring E-mail Alerts" on page 243. Understanding the Redundant CMC Environment You can install a standby CMC that takes over if your primary CMC fails. Failovers can occur when you: • Run the RACADM cmcchangeover command. (See "cmcchangeover" on page 267.
Primary CMC Election Process There is no difference between the two CMC slots; that is, slot does not dictate precedence. Instead, the CMC that is installed or booted first assumes the role of the active CMC. If AC power is applied with two CMCs installed, the CMC installed in CMC chassis slot 1 (the left) normally assumes the active role. The active CMC is indicated by the blue LED.
Configuring CMC to Use Command Line Consoles This section provides information about the CMC command line console (or serial/Telnet/Secure Shell console) features, and explains how to set up your system so you can perform systems management actions through the console. For information on using the RACADM commands in CMC via the command line console, see "Using the RACADM Command Line Interface" on page 65.
Using SSH With the CMC SSH is a command line session that includes the same capabilities as a Telnet session, but with session negotiation and encryption to improve security. The CMC supports SSH version 2 with password authentication. SSH is enabled on the CMC by default. NOTE: The CMC does not support SSH version 1. When an error occurs during the login procedure, the SSH client issues an error message. The message text is dependent on the client and is not controlled by the CMC.
The CMC SSH implementation supports multiple cryptography schemes, as shown in Table 3-1. Table 3-1.
• Linux Telnet in an Xterm • Microsoft® Telnet Perform the steps in the following subsections to configure your type of terminal software. If you are using Microsoft Telnet, configuration is not required. Configuring Linux Minicom for Serial Console Emulation Minicom is a serial port access utility for Linux. The following steps are valid for configuring Minicom version 2.0. Other Minicom versions may differ slightly but require the same basic settings.
10 In the Modem Dialing and Parameter Setup menu, press to clear the init, reset, connect, and hangup settings so that they are blank. 11 Press to save each blank value. 12 When all specified fields are clear, press to exit the Modem Dialing and Parameter Setup menu. 13 Select Save setup as config_name and press . 14 Select Exit From Minicom and press . 15 At the command shell prompt, type minicom .
Running Telnet Using Windows XP or Windows 2003 If your management station is running Windows XP or Windows 2003, you may experience an issue with the characters in a CMC Telnet session. This issue may occur as a frozen login where the return key does not respond and the password prompt does not appear. To fix this issue, download hotfix 824810 from the Microsoft Support website at support.microsoft.com. See Microsoft Knowledge Base article 824810 for more information.

Using a Serial or Telnet Console When you connect to the CMC command line, you are able to enter these commands: Table 3-3. CMC Command Line Commands Command Description racadm RACADM commands begin with the keyword racadm and are followed by a subcommand, such as getconfig, serveraction, or getsensorinfo. See "Using the RACADM Command Line Interface" on page 65 for details on using RACADM. connect Connects to a server or I/O module for debugging.
There are up to six IOMs on the managed system. To connect to an IOM, type: connect switch-n where n is an IOM number 1 through 6. IOMs are labeled A1, A2, B1, B2, C1, and C2. (See Table 9-1 for an illustration of the placement of IOMs in the chassis.) When you reference the IOMs in the connect command, the IOMs are mapped to switches as shown in Table 3-4. Table 3-4.
Using the RACADM Command Line Interface RACADM provides a set of commands that allow you to configure and manage the CMC through a text-based interface. RACADM can be accessed using a Telnet/SSH or serial connection, using the Dell CMC console on the iKVM, or remotely using the RACADM command line interface installed on a management station.
Using a Serial or Telnet Console You can log in to the CMC either through a serial or Telnet/SSH connection, or through Dell CMC console on iKVM. To configure the CMC for serial or remote access, see "Configuring CMC to Use Command Line Consoles" on page 53. Commonly used subcommand options are listed in Table 4-2. A complete list of RACADM subcommands is listed in "RACADM Subcommands" on page 263.
When run without options or subcommands, RACADM displays syntax information and instructions on how to access subcommands and help. To list syntax and command-line options for individual subcommands, type: racadm help RACADM Subcommands Table 4-1 provides a brief list of common subcommands used in RACADM. For a complete list of RACADM subcommands, including syntax and valid entries, see "RACADM Subcommands" on page 263.

The RACADM remote capability on the CMC is enabled by default.
NOTE: The RACADM remote capability is supported only on management stations through a supported browser. See "Supported Web Browsers" on page 27 for more information. NOTE: When using the RACADM remote capability, you must have write permissions on the folders where you are using the RACADM subcommands involving file operations. For example: racadm getconfig -f -r or racadm sslcertupload -t 1 -f c:\cert\cert.
This section explains how to perform the initial CMC network configuration using RACADM commands. All of the configuration described in this section can be performed using the front panel LCD. See "Configuring Networking Using the LCD Configuration Wizard" on page 42. NOTICE: Changing your CMC Network settings may disconnect your current network connection.
Configuring the Network LAN Settings NOTE: To perform the following steps, you must have Chassis Configuration Administrator privilege. NOTE: The LAN settings, such as community string and SMTP server IP address, affect both the CMC and the external settings of the chassis. NOTE: If you have two CMCs (primary and standby) on the chassis, and they are both connected to the network, the standby CMC automatically assumes the network settings in the event of failover of the primary CMC.
Setting Static DNS IP addresses NOTE: These settings are not valid unless the DCHP for DNS address feature is disabled. To set the preferred DNS IP address, type: racadm config -g cfgLanNetworking -o cfgDNSServer1 To set the secondary DNS IP address, type: racadm config -g cfgLanNetworking -o cfgDNSServer2 Configuring DNS Settings • CMC Registration.
Configuring Auto Negotiation, Duplex Mode, and Network Speed When enabled, the auto negotiation feature determines whether the CMC automatically sets the duplex mode and network speed by communicating with the nearest router or switch. Auto negotiation is enabled by default.
Configuring the Network Security Settings NOTE: To perform the following steps, you must have Chassis Configuration Administrator privilege. Enabling IP Range Checking IP filtering compares the IP address of an incoming login to the IP address range that is specified in the following cfgRacTuning properties: • cfgRacTuneIpRangeAddr • cfgRacTuneIpRangeMask The cfgRacTuneIpRangeMask property is applied to both the incoming IP address and to the cfgRacTuneIpRangeAddr properties.
To verify if a user exists, open a Telnet/SSH text console to the CMC, log in, and type: racadm getconfig -u or type the following command once for each index of 1–16: racadm getconfig -g cfgUserAdmin -i NOTE: You can also type racadm getconfig -f to view or edit the myfile.cfg file, which includes all CMC configuration parameters. Several parameters and object IDs are displayed with their current values.
Example The following example describes how to add a new user named "John" with a "123456" password and LOGIN privilege to the CMC. NOTE: See Table B-1 for a list of valid bit mask values for specific user privileges. The default privilege value is 0, which indicates the user has no privileges enabled.
The following example illustrates the command syntax that can be used to delete a CMC user: racadm config -g cfgUserAdmin -o cfgUserAdminUserName -i "" A null string of double quote characters ("") instructs the CMC to remove the user configuration at the specified index and reset the user configuration to the original factory defaults. Configuring SNMP and E-mail Alerting You can configure the CMC to send SNMP event traps and/or e-mail alerts when certain events occur on the chassis.
2 Modify the configuration file using a plain-text editor (optional). Any formatting in the configuration file may corrupt the RACADM database. 3 Use the newly created configuration file to modify a target CMC. At the command prompt, type: racadm config -f myfile.cfg 4 Reset the target CMC that was configured. At the command prompt, type: racadm reset The getconfig -f myfile.cfg subcommand (step 1) requests the CMC configuration for the primary CMC and generates the myfile.cfg file.
correctness, and all errors display. Write commands are not transmitted to the CMC if an error is found in the .cfg file. You must correct all errors before any configuration can take place. To check for errors before you create the configuration file, use the -c option with the config subcommand. With the -c option, config only verifies syntax and does not write to the CMC. Use the following guidelines when you create a .
Parsing Rules • Lines that start with a hash character (#) are treated as comments. A comment line must start in column one. A "#" character in any other column is treated as a # character. Some modem parameters may include # characters in their strings. An escape character is not required. You may want to generate a .cfg from a racadm getconfig -f .cfg command, and then perform a racadm config -f .cfg command to a different CMC, without adding escape characters.
[cfgLanNetworking] -{group name} cfgNicIpAddress=143.154.133.121 {object value} • The .cfg parser ignores an index object entry. You cannot specify which index is used. If the index already exists, it is either used or the new entry is created in the first available index for that group. The racadm getconfig -f .cfg command places a comment in front of index objects, allowing you to see the included comments.
Modifying the CMC IP Address When you modify the CMC IP address in the configuration file, remove all unnecessary = entries. Only the actual variable group’s label with [ and ] remains, including the two = entries pertaining to the IP address change. Example: # # Object Group "cfgLanNetworking" # [cfgLanNetworking] cfgNicIpAddress=10.35.10.110 cfgNicGateway=10.35.10.
Troubleshooting Table 4-3 lists common problems related to remote RACADM. Table 4-3. Using the Serial and RACADM Commands: Frequently Asked Questions Question Answer After performing a CMC reset (using the You must wait until the CMC completes RACADM racreset subcommand), I issue the reset before issuing another a command and the following message is command.
Using the CMC Web Interface The CMC provides a Web interface that enables you to configure the CMC properties and users, perform remote management tasks, and troubleshoot a remote (managed) system for problems. For everyday chassis management, use the CMC Web interface. This chapter provides information about how to perform common chassis management tasks using the CMC Web interface.
Logging In NOTE: To log in to the CMC, you must have a CMC account with Log In to CMC privilege. NOTE: The default CMC user name is root, and the password is calvin. The root account is the default administrative account that ships with the CMC. For added security, Dell strongly recommends that you change the default password of the root account during initial setup. NOTE: The CMC does not support extended ASCII characters, such as ß, å, é, ü, or other characters used primarily in non-English languages.
Configuring Basic CMC Settings Setting the Chassis Name You can set the name used to identify the chassis on the network. (The default name is "Dell Rack System.") For example, an SNMP query on the chassis name will return the name you configure. To set the chassis name: 1 Log in to the CMC Web interface. The Component Health page displays. 2 Click the Setup tab. The General Chassis Settings page displays. 3 Type the new name in the Chassis Name field, and then click Apply.
Viewing Power Budget Status The Power Budget Status page displays the power budget status for the chassis, servers, and chassis power supply units (PSUs).

Viewing the Health Status of IOMs The I/O Modules Status page provides overviews of all IOMs associated with the chassis. For instructions on viewing IOM health through the Web interface or RACADM, see "Monitoring IOM Health" on page 232. Viewing the Health Status of the Fans NOTE: During updates of CMC or iDRAC firmware on a server, some or all of the fan units in the chassis will spin at 100%. This is normal.
Table 5-4. Item Fans Health Status Information (continued) Description Severe Indicates at least one Failure alert has been issued. Severe status represents a system failure on the IOM, and corrective action must be taken immediately to prevent overheating and system shutdown. Unknown Displayed when the chassis is first powered on. In the event of a communication failure between the CMC and the fan unit, the CMC cannot obtain or display health status for the fan unit.
To view the health status of the PSUs: 1 Log in to the CMC Web interface. 2 Select Power Supplies in the system tree. The Power Supply Status page displays. Table 5-5 provides descriptions of the information provided on the Power Supply Status page. Table 5-5. Power Supply Health Status Information Item Description Present Indicates whether the power supply is present (Yes or No). Health OK Indicates that the PSU is present and communicating with the CMC. Indicates that the health of the PSU is OK.
Viewing Status of the Temperature Sensors The Temperature Sensors Information page displays the status and readings of the temperature probes on the entire chassis (chassis, servers, IOMs, and iKVM). NOTE: The temperature probes value cannot be edited. Any change beyond the threshold will generate an alert that will cause the fan speed to vary. For example, if the CMC ambient temperature probe exceeds threshold, the speed of the fans on the chassis will increase.
Configuring CMC Network Properties Setting Up Initial Access to the CMC NOTE: You must have Chassis Configuration Administrator privilege to set up CMC network settings. 1 Log in to the Web interface. 2 Select Chassis in the system tree. The Component Health page appears. 3 Click the Network/Security tab.

If this option is checked: • The CMC communicates with and is accessible over the computer network. • The Web interface, CLI (remote RACADM), WSMAN, Telnet, and SSH associated with the CMC are available. If this option is not checked: • The CMC NIC cannot communicate over the network.
Table 5-7. Network Settings (continued) Setting Description Use DHCP (For CMC NIC IP Address) Enables the CMC to request and obtain an IP address from the Dynamic Host Configuration Protocol (DHCP) server automatically. Default: Checked (enabled) If this option is checked, the CMC retrieves IP configuration (IP address, mask, and gateway) automatically from a DHCP server on your network. The CMC will always have a unique IP address allotted over your network.
Table 5-7. Network Settings (continued) Setting Description Use DHCP to Obtain DNS Server Addresses Obtains the primary and secondary DNS server addresses from the DHCP server instead of the static settings. Default: Checked (enabled). NOTE: If Use DHCP (For NIC IP Address) is enabled, then enable the Use DHCP to Obtain DNS Server Addresses property. If this option is checked, the CMC retrieves its DNS IP address automatically from a DHCP server on your network.
Table 5-7. Network Settings (continued) Setting Description DNS CMC Name Displays the CMC name only when Register CMC on DNS is selected. The default CMC name is CMC_service_tag, where service tag is the service tag number of the chassis. Example: CMC-00002 Use DHCP for DNS Domain Name Uses the default DNS domain name. This check box is active only when Use DHCP (For NIC IP Address) is selected. Default: Disabled DNS Domain Name The default DNS Domain Name is a blank character.
Table 5-7. Network Settings (continued) Setting Description Duplex Mode Set the duplex mode to full or half to match your network environment. Implications: If Auto Negotiation is turned On for one device but not the other, then the device using auto negotiation can determine the network speed of the other device, but not the duplex mode. In this case, duplex mode defaults to the half duplex setting during auto negotiation. such a duplex mismatch will result in a slow network connection.
Table 5-8. Network Security Page Settings (continued) Settings Description IP Range Mask Defines a specific range of IP addresses that can access the CMC, a process called IP range checking. IP range checking allows access to the CMC only from clients or management stations whose IP addresses are within the userspecified range. All other logins are denied. For example: IP range mask: 255.255.255.0 (11111111.11111111.11111111.00000000) IP range address:192.168.0.255 (11000000.10101000.00000000.
Adding and Configuring CMC Users To manage your system with the CMC and maintain system security, create unique users with specific administrative permissions (or role-based authority). For additional security, you can also configure alerts that are e-mailed to specific users when a specific system event occurs. User Types There are two types of users: CMC users and iDRAC users. CMC users are also known as "chassis users." Since iDRAC resides on the server, iDRAC users are also known as "server users.
Table 5-9. User Types Privilege Description CMC Login User Users who have the CMC Login User privilege can log in to CMC. A user with only the login privilege can view all of the CMC data but cannot add or modify data or execute commands. It is possible for a user to have other privileges without the login privilege. This feature is useful when a user is temporarily disallowed to login. When that user’s login privilege is restored, the user retains all the other privileges previously granted.
Table 5-9. User Types (continued) Privilege Description User Configuration Administrator Users who have the User Configuration Administrator privilege can: • Add a new user • Delete an existing user • Change a user's password • Change a user's privileges • Enable or disable a user's login privilege but retain the user's name and other privileges in the database. Clear Logs Administrator CMC users who have the Clear Administrator privilege can clear the hardware log and CMC log.
Table 5-9. User Types (continued) Privilege Description Server Administrator The Server Administrator privilege is a blanket privilege granting a CMC user all rights to perform any operation on any servers present in the chassis. When a user with CMC Server Administrator privilege issues an action to be performed on a server, the CMC firmware sends the command to the targeted server without checking the user's privileges on the server.

The CMC Web server includes a Dell self-signed SSL digital certificate (Server ID). To ensure high security over the Internet, replace the Web server SSL certificate by submitting a request to the CMC to generate a new Certificate Signing Request (CSR). Certificate Signing Request (CSR) A CSR is a digital request to a certificate authority (referred to as a CA in the Web interface) for a secure server certificate.
Generating a New Certificate Signing Request To ensure security, Dell strongly recommends that you obtain and upload a secure server certificate to the CMC. Secure server certificates ensure the identity of a remote system and that information exchanged with the remote system cannot be viewed or changed by others. Without a secure server certificate, the CMC is vulnerable to access from unauthorized users. Table 5-2.
certificate you receive from the certificate authority. After you receive the server certificate from the certificate authority, you must then upload it to the CMC. NOTE: For the CMC to accept the server certificate returned by the certificate authority, authentication information contained in the new certificate must match the information that was stored on the CMC when the CSR was generated. NOTICE: When a new CSR is generated, it overwrites any previous CSR on the CMC.

Using the CMC Web Interface
Using the CMC With Microsoft Active Directory A directory service maintains a common database of all information needed for controlling network users, computers, printers, and so on. If your company uses the Microsoft® Active Directory® service software, you can configure the software to provide access to the CMC. This allows you to add and control CMC user privileges to your existing users in your Active Directory software.
Extended Schema Overview There are two ways to enable Extended Schema Active Directory: • Using the CMC Web interface. For instructions, see "Configuring the CMC With Extended Schema Active Directory and the Web Interface" on page 161. • Using the RACADM CLI tool. For instructions, see "Configuring the CMC With Extended Schema Active Directory and RACADM" on page 163. Active Directory Schema Extensions The Active Directory data is a distributed database of Attributes and Classes.
The Association property links together users or groups with a specific set of privileges to one or more RAC devices. This model provides an Administrator maximum flexibility over the different combinations of users, RAC privileges, and RAC devices on the network without adding too much complexity.
Figure 6-1. Typical Setup for Active Directory Objects Association Object User(s) Group(s) Privilege Object RAC Device Object(s) RAC Privilege Object The Association Object allows for as many or as few users and/or groups as well as RAC Device Objects. However, the Association Object only includes one Privilege Object per Association Object. The Association Object connects the "Users" who have "Privileges" on the RACs (CMCs).
Figure 6-2. Setting Up Active Directory Objects in a Single Domain AO1 Group1 User1 User2 AO2 Priv1 User3 Priv2 RAC1 RAC2 To configure the objects for the single domain scenario: 1 Create two Association Objects. 2 Create two RAC Device Objects, RAC1 and RAC2, to represent the two CMCs. 3 Create two Privilege Objects, Priv1 and Priv2, in which Priv1 has all privileges (administrator) and Priv2 has login privilege. 4 Group user1 and user2 into Group1.
Domain1, and user2 and user 3 are in Domain2. In this scenario, configure user1 and user 2 with administrator privileges to both CMCs and configure user3 with login privileges to the RAC2 card.

Power Management Overview The M1000e chassis ships with either three power supply units (PSUs) or six, the maximum. If your chassis has three PSUs, you can add up to three more. The PSUs supply power to the chassis and all the modules in the chassis: CMC, IOM, iKVM, fans, front panel LCD and servers. The CMC manages the power budget for all the chassis modules.
Figure 7-1. Chassis With Six-PSU Configuration PSUs Dynamic PSU Engagement Dynamic PSU engagement is a configurable option that enables the CMC to conserve power by powering-off unused PSUs and keeping them in standby mode in case more power is required. This saves power by increasing the utilization of the PSUs that remain active so that they are used more efficiently.
• The redundancy policy • The capabilities and maximum efficiency point of the PSU configuration Table 7-1. Power Allocation in Compute vs.
Table 7-2. Default Redundancy Configuration PSU Configuration Default Redundancy Policy Default Dynamic PSU Engagement Setting Six PSUs AC Redundancy Disabled Three PSUs No Redundancy Disabled AC Redundancy For AC Redundancy mode to operate at optimal power, you must have six PSUs in your chassis. You can set your chassis to operate in AC Redundancy mode with fewer than six PSUs, but it will operate in a degraded state. In AC Redundancy mode, all six PSUs will be active.
No Redundancy Power from up to three PSUs is used to power on the entire chassis, including the servers, IOMs, iKVM, front panel LCD, fans, and primary CMC. NOTICE: The No Redundancy mode uses only three PSUs at a time, without backup. Failure of one of the three PSUs being used could cause servers to lose power and data. Power Conservation and Power Budget Changes The CMC can perform power conservation when the user-configured maximum power limit is reached. Power conservation is disabled by default.

No Redundancy Power Grid #1 Power Supply #1 Power Supply #2 Power Supply #3 Blank Slot #4 Blank Slot #5 Blank Slot #6 Chassis DC Power Bus Single Power Grid: No protection against grid or power supply failure New Server Engagement Policy When a new server is powered on, the CMC may need to decrease power to lower priority servers to allow more power for the new server if adding the new server exceeds the power available for the system.
Table 7-3 describes the actions taken by the CMC when a new server is powered on in the scenario described above. Table 7-3.
PSU Power-downs and Removals With a No Redundancy Policy The CMC may begin conserving power when you power-down or gracefully extract a PSU. The CMC decreases power to the lower priority servers until power consumption is supported by the remaining PSUs in the chassis. If you power-down or remove more than one PSU, the CMC evaluates power needs again when the second PSU is removed to determine the firmware response.
Using the Web Interface To view the health status of the PSUs: 1 Log in to the CMC Web interface. 2 Select Power Supplies in the system tree. The Power Supply Status page displays. Table 7-5 provides descriptions of the information provided on the Power Supply Status page. Table 7-5.

The timestamp is displayed in the format hh:mm:ss MM/DD/YYYY, where hh is hours (0–24), mm is minutes (00–60), ss is seconds (00–60), MM is the month (1–12), DD is the day, 1–31, and YYYY is the year.
Table 7-8. System Power Policy Configuration Item Description System Max AC Displays the user-defined maximum power consumption limit for Power Limit the entire system (chassis, CMCs, servers, I/O modules, PSUs, iKVM, and fans). The CMC enforces this limit by throttling (if enabled) or by powering off lower priority servers (if throttling is not enabled). System AC Displays the maximum amount of power, in watts, beyond which Power Warning the CMC takes action to reduce power consumption.
Table 7-8. System Power Policy Configuration (continued) Item Description Redundancy Policy Indicates the current redundancy configuration: AC Redundancy, Power Supply Redundancy, and No Redundancy. AC Redundancy — Power input is load-balanced across all PSUs. Three of the PSUs are connected to one AC grid and the other three are connected to another grid. When the system is running optimally in AC Redundancy mode, power is load-balanced across all active supplies.
Table 7-9. Power Budgeting Item Description System DC Max Power Capacity Displays the Maximum DC power, in watts, the available PSUs can supply to the system. DC Redundancy Reserve Indicates the amount of redundant power (in watts) in reserve that can be utilized in the event of an AC grid or PSU failure. When the chassis is configured to operate in AC Redundancy mode, the DC Redundancy Reserve is the amount of reserve power that can be utilized in the event of an AC grid failure.
Table 7-10. Server Modules Item Description Slot # Displays the location of the server module. The Slot # is a sequential number (1–16) that identifies the server module by its location within the chassis. Name Displays the server name. The server name can be redefined by the user.

Using the iKVM Module Overview The local access KVM module for your Dell™ M1000e server chassis is called the Avocent® Integrated KVM Switch Module, or iKVM. The iKVM is an analog keyboard, video, and mouse switch that plugs into your chassis. It is an optional, hot-pluggable module to the chassis that provides local keyboard, mouse, and video access to the servers in the chassis, and to the active CMC’s command line.
The CMC identifies a slot by assigning it a unique name. To change slot names using the CMC Web interface, see "Editing Slot Names" on page 91. To change a slot name using RACADM, see "setslotname" on page 315. Video The iKVM video connections support video display resolutions ranging from 640 x 480 at 60 Hz up to 1280 x 1024 at 60 Hz. Plug and Play The iKVM supports Display Data Channel (DDC) Plug and Play, which automates video monitor configuration, and is compliant with the VESA DDC2B standard.
For example, if you have iKVM connections in the front panel and ACI, the front panel connection remains active while the ACI connection is disabled. If you have ACI and rear connections, the ACI connection takes precedence. Tiering Through the ACI Connection The iKVM allows tiered connections with servers and the iKVM’s CMC command line console, either locally through a Remote Console Switch port or remotely through the Dell RCS® software.

I/O Fabric Management The chassis can hold up to six I/O modules (IOMs), each of which can be pass-through or switch modules. The IOMs are classified into three groups: A, B, and C. Each group has two slots: Slot 1 and Slot 2. The slots are designated with letters, from left to right, across the back of the chassis: A1 | B1 | C1 | C2 | B2 | A2. Each server has slots for two mezzanine cards (MCs) to connect to the IOMs. The MC and the corresponding IOM must have the same fabric.
Figure 9-1 shows the location of IOMs in the chassis. The location of each IOM in the chassis is indicated by its group number (A, B, or C) and slot number (1 or 2). On the chassis, the IOM slot names are marked A1, A2, B1, B2, C1, or C2. Figure 9-1. Rear View of a Chassis, Showing the Location of the IOMs Slots A1, B1, C1 Slots C2, B2, A2 The CMC creates entries in both the hardware log and CMC logs for invalid hardware configurations.
NOTE: Fabric verification for server MCs is performed only when the chassis is powered on. When the chassis is on standby power, the iDRACs on the server modules remain powered off and thus are unable to report the server's MC fabric type. The MC fabric type may not be reported in the CMC user interface until the iDRAC on the server is powered on.
For information about the CMC and hardware logs, see "Viewing the Event Logs" on page 251. Fresh Power-up Scenario When the chassis is plugged in and powered up, the I/O modules have priority over the servers. The first IOM in each group is allowed to power up before the others. At this time, no verification of their fabric types is performed. If there is no IOM on the first slot of a group, the module on the second slot of that group powers up.
Table 9-1 provides descriptions of the information provided on the I/O Modules Status page. Table 9-1. I/O Modules Health Status Information Item Description Present Indicates whether the IOM is Present or Absent. Health OK Indicates that the IOM is present and communicating with the CMC.
