The Chassis Controller Status page is displayed. For more information, see the Online Help. Viewing Information and Health Status of All Servers To view the health status of all the servers, do one of the following: ● Click Chassis Overview. The Chassis Health page displays a graphical overview of all the servers installed in the chassis. Server health status is indicated by the overlay of the server subgraphic. For more information about the chassis health, see the Online Help.
NOTE: The CMC monitors the temperature sensors in the chassis and automatically adjust the fan speed as needed. However, you can override to maintain a minimum fan speed by the racadm fanoffset command. When overriden using this command, the CMC will always run the fan to the selected speed even though the chassis does not require the fans to run at that speed. CMC generates an alert and increases the fan speeds when the following events occur: ● CMC ambient temperature threshold is exceeded.
When enabled, ECM will only increase the cooling capacity to the server slots within the chassis. It is also important to note that ECM is not designed to provide increased cooling to the servers at all times. Even with ECM enabled, the higher blower speeds will only be seen when the increased cooling is needed. Examples of this situation include high levels of server utilization or stress, and high ambient temperatures. By default, ECM is off.
The Temperature Sensors Status page displays the status and readings of the temperature probes on the entire chassis (chassis and servers). For more information, see Online Help. NOTE: The temperature probes value cannot be edited. Any change beyond the threshold generates an alert that causes the fan speed to vary. For example, if the CMC ambient temperature probe exceeds the threshold, the speed of the fans on the chassis increases.
6 Configuring CMC Chassis Management Controller enables you to configure properties, set up users, and alerts to perform remote management tasks. Before you begin configuring the CMC, you must first configure the CMC network settings to allow CMC to be managed remotely. This initial configuration assigns the TCP/IP networking parameters that enable access to the CMC. For more information, see Setting Up Initial Access to CMC. You can configure CMC using Web interface or RACADM.

13 Managing Fabrics The chassis supports a fabric type, which is Fabric A. Fabric A is used by the single I/O Module, and is always connected to the on-board Ethernet adapters of the servers. The chassis has only one I/O module (IOM), where the IOM is a pass-through or switch module. The I/O Module is classified as group A. Chassis IOM uses a discrete data path called Fabric, and it is named A. The Fabric A supports only Ethernet.
Configuring Network Settings for IOM Using CMC Web Interface To configure the network settings for I/O Module: 1. In the left pane, click Chassis Overview, click I/O Module Overview, and then click Setup. Alternatively, to configure the network settings of the only available I/O module that is A, click A Gigabit Ethernet, and then click Setup. On the Configure I/O Module Network Settings page, type appropriate data, and then click Apply. 2.
14 Managing and Monitoring Power The PowerEdge VRTX chassis is the most power-efficient modular server enclosure. It is designed to include highly efficient power supplies and fans, has an optimized layout for the air to flow more easily through the system, and contains power-optimized components throughout the enclosure.
Redundancy Policies Redundancy policy is a configurable set of properties that determine how CMC manages power to the chassis. The following redundancy policies are configurable with or without dynamic PSU engagement: ● Grid redundancy ● Power supply redundancy Grid Redundancy Policy The purpose of the Grid redundancy policy is to enable a modular enclosure system to operate in a mode in which it can tolerate AC power failures.
To operate remaining PSUs at their maximum efficiency, use the following power redundancy modes: ● PSU Redundancy mode with DPSE provides power efficiency. At least two supplies are online, with one PSU required to power the configuration, and one to provide redundancy in case of a PSU failure. PSU Redundancy mode offers protection against the failure of any one PSU, but offers no protection in the event of an AC grid loss.
Power Supply Redundancy When power supply redundancy is enabled, a PSU in the chassis is kept as a spare, ensuring that the failure of any one PSU does not cause the servers or chassis to turn off. Power supply redundancy mode requires minimum two PSUs. Additional PSUs, if present, are utilized to improve power efficiency of the system if DPSE is enabled. Subsequent failures after loss of redundancy may cause the servers in the chassis to turn off.
● I/O module turned off ● Storage adapters, PCIe cards, physical disk drive, and main board turned off ● Transition of the chassis to a turned-off state You can reconfigure the System Input Power Cap when the chassis is either turned on or turned off. Server Slot Power Priority Settings CMC allows you to set a power priority for each of the four server slots in an enclosure. The priority settings are 1 (highest) through 9 (lowest).
For example, to set the priority level to 1 for the server in slot 4, type the following command: racadm config -g cfgServerInfo -o cfgServerPriority -i 4 1 Viewing Power Consumption Status CMC provides the actual input power consumption for the entire system. Viewing Power Consumption Status Using CMC Web Interface In the left pane, click Chassis Overview > Power > Power Monitoring.
Redundancy Status and Overall Power Health The redundancy status is a factor in determining the overall power health. When the power redundancy policy is set, for example, to Grid Redundancy and the redundancy status indicates that the system is operating with redundancy, the overall power health is typically OK. If the PSU installed on a chassis fails owing to some reason, the overall power health status of the chassis is displayed as Non-Critical.
If the subsequent power capacity or the user power capacity is greater than the server allocations, servers have degraded performance or, in an extrement case, servers may be turned off. Both conditions are in reverse-priority order; that is, the low-priority servers are turned off first. The following table provides the firmware response to a PSU turnoff, or removal as it applies to various PSU redundancy configurations. Table 38.

Remote Logging Power consumption can be reported to a remote syslog server. Total chassis power consumption, minimum, maximum, and average power consumption over a collection period can be logged. For more information about enabling this feature and configuring the collection or logging interval, see Managing and Monitoring Power. External Power Management CMC power management is optionally controlled by the OpenManage Power Center (OMPC). For more information, see the OMPC User’s Guide.
Configuring Power Budget and Redundancy Using RACADM NOTE: To perform power management actions, you must have the Chassis Configuration Administrator privilege. To enable and set the redundancy policy: 1. Open a serial/Telnet/SSH text console to CMC and log in. 2. Set properties as needed: ● To select a redundancy policy, type: racadm config -g cfgChassisPower -o cfgChassisRedundancyPolicy where is 1 (Grid Redundancy), and 2 (Power Supply Redundancy). The default value is 2.
● To determine if the power remote logging feature is enabled, enter the following command: racadm getconfig -g cfgRemoteHosts -o cfgRhostsSyslogPowerLoggingEnabled ● To determine the power remote logging interval, enter the following command: racadm getconfig -g cfgRemoteHosts -o cfgRhostsSyslogPowerLoggingInterval The power remote logging feature is dependent on previously configured remote syslog hosts having been .

17 Troubleshooting and Recovery This section explains how to perform tasks related to recovering and troubleshooting problems on the remote system using the CMC web interface. ● Viewing chassis information. ● Viewing the event logs. ● Gathering configuration information, error status, and error logs. ● Using the diagnostic console. ● Managing power on a remote system. ● Managing Lifecycle Controller jobs on a remote system. ● Reset components. ● Troubleshooting Network Time Protocol (NTP) problems.
Gathering Configuration Information, Chassis Status, and Logs Using RACDUMP The racdump subcommand provides a single command to get comprehensive chassis status, configuration state information, and the historic event logs.
First Steps to Troubleshoot a Remote System The following questions are commonly used to troubleshoot high-level issues in the managed system: ● Is the system turned on or turned off? ● If turned on, is the operating system functioning, not responding, or stopped functioning? ● If turned off, did the power turn off unexpectedly? Power Troubleshooting The following information helps you to troubleshoot power supply and power-related issues: ● Problem: Configured the Power Redundancy Policy to Grid Redundanc
○ Resolution: This can occur if the System Input Power Cap has been configured to a value that results in an increased power need by fans having to be made up by reduction in the power allocation to the servers. User can increase the System Input Power Cap to a higher value that allow for additional power allocation to the fans without an impact on server performance. Troubleshooting Alerts Use the CMC log and the trace log to troubleshoot CMC alerts.
Viewing Hardware Logs Using RACADM To view the hardware log using RACADM, open a serial/Telnet/SSH text console to CMC, log in, and type: racadm getsel To clear the hardware log, type: racadm clrsel Viewing Chassis Log CMC generates a log of the chassis-related events. CMC provides alert capabilities through System Event Log (SEL), SNMP, and Email interfaces. SPERC is inserted while one or more PowerEdge serves are powered on.
Resetting Components You can reset the active CMC, or virtually reseat servers making them to behave as if they were removed and reinserted. If the chassis has a standby CMC, resetting the active CMC causes a failover and the standby CMC becomes active. NOTE: To reset components, you must have Debug Command Administrator privilege. To reset the components using the CMC Web interface, 1. In the left pane, click Chassis Overview > Troubleshooting > Reset Components. The Reset Components page is displayed. 2.
If you attempt to configure a Windows-based NTP server, it may help to increase the MaxDist parameter for ntpd. Before changing this parameter, understand all the implications, since the default setting must be large enough to work with most NTP servers.
