2. C-75 Overview C-75 is a 3x3 802.11a/b/g/n/ac access point. This chapter provides an overview of the C-75 and describes front and the rear panels. The front panel of the C-75 has 5 LEDs that indicate the working of the device. Figure 2-1 Front Panel of C-75 The following table indicates the device states based on the LEDs.
Solid Orange Slow Blink On/Off Off Off Off Any Any Off Off The AP is unable to connect to the server. The AP is not powered on or it is in the process of starting up. Note: LAN2 is ON if the link is up, and is OFF if the link is down. The 2.4 GHz and 5 GHz LEDs blink when there is activity on the respective radio(s).
The rear panel of the C-75 has an Ethernet port labeled LAN1, that enables you to connect the device a wired LAN through a switch or a hub and provides the power for the device by using the 802.3af standard. Figure 2-2 Rear Panel of C-75 Table 2-2 Rear Panel Port Settings for C-75 Port Description Connector Type Speed/Protocol DC IN Enables you to connect to and power on device using 12 V DC power with 2.5 ampere.
Figure 2-3. Right side of C-75 The Reset Pin Hole and the USB port are on the right side of the device as shown in the figure above. The Reset Pin Hole resets the C-75 device to factory defaults. To reset the device, power cycle the device (remove the power cable once and connect it back again) and while plugging the power cable back into the power source, press and hold down the Reset Pin Hole for 45 seconds until the power, LAN1, 2.4 GHz LEDs go green.
3. Installing the C-75 Clients can connect to your corporate network in wireless mode through the C-75 AP(s). The C-75 must be plugged into your corporate network to perform the above-mentioned operation. Important: To prevent disconnection or tampering by unauthorized personnel, it is extremely important to install the device such that it is difficult to unplug the device from the network or from the power outlet.
Wall/ Ceiling Mounting Use the mounting bracket to install the C-75 on the ceiling. To mount the device: 1. Attach the mounting bracket to the wall or ceiling by using the mounting hardware kit. 2. Insert the provided short screws into the bottom cover of the C-75 device. 3. Leave enough of the screws exposed to ensure that the unit can be attached to the mounting bracket. 4.
Power On C-75 A C-75 device can be powered on by 802.3af Class 0 Power Over Ethernet (PoE) of Nominal input voltage 48V DC. You can connect the device to the network using PoE or a power adapter. Connect C-75 to the Network To connect C-75 to the network, perform the following steps. 1. Ensure that a DHCP server is already available on the network to enable network configuration of the C75.
2. Add the DNS entry wifi-security-server on all DNS servers. This entry should point to the IP address of the server. 3. Ensure that DHCP is running on the subnet to which the device will be connected. Important: If DHCP is not enabled on a subnet, the device cannot connect to that subnet with zero-configuration. If the DNS entry is not present on the DNS servers or you do not have the DHCP server running on the subnet, you must manually configure the device.
Figure 3-4. Power Up C-75 To connect C-75 to the network, perform the following steps: 1. Ensure that a DHCP server is available on the network to provide network configuration to the C-75. 2. Connect one end of the network interface cable to the Ethernet port at the rear of the C-75. 3. Connect the other end of the network interface cable to an Ethernet jack on the desired subnet. Wait until the device is ready (approx. 10 mins). Figure 3-5. Connect C-75 to network 4. Check the status LEDs on the device.
5. Log on to the server through SSH and run the get sensor list command. You would see a list of all AirTight devices that are recognized by the server. AirTight Cloud Services users can go to the Devices tab and check whether the device is visible under the Devices tab. The device is configured and ready to go operational. Note: If the zero configuration is not successful, the device must be configured manually. Refer to Manually Configuring C-75 for details.
4. Manually Configuring C-75 Important: If the installation in the previous chapter was successful, stop! You do not need to configure the device manually. Introduction Manual configuration of C-75 is typically required in the following cases: Devices cannot connect to the server through zero-configuration. The DNS entry for the server has been changed to an entry other than wifi-security-server or a DNS server is not present in the network. This is applicable for multi-server installations.
Figure 4-1 The set server discovery Command Note: If IP address/ host name based discovery is being used and more than one server is present on the network, then you must enter the IP address of the appropriate server. Configure Network Settings Configure a static IP address in absence of a DHCP server 1. Connect a crossover cable from the computer to the Ethernet port of C-75. 2. Configure the LAN IP address on the computer in the subnet 192.168.1.0/24. 3. SSH to IP address: 192.168.1.
To configure the communication key or passphrase kindly refer to Appendix A: AP-Server Mutual Authentication for further details.
5. C-75 Config Shell Commands The following tables detail the C-75 config shell commands.
Command Description set erase Sets the erase character to ^H. set interface Sets network interface properties such as auto negotiation, speed, and duplex settings. set ip config Runs through the current VLAN and IP config wizard. set server discovery Sets the server discovery information. set vlan config Configures list of VLANs and their network settings, to be monitored by ND. set ipv6 config Sets IPv6 network settings. set communication key Sets the AP-server shared secret.
Table 5-3. Miscellaneous commands Other Commands Command Description exit Exits the config shell session help Displays help for all commands help set Displays help for ‘set’ commands help get Displays help for ‘get’ commands help other Displays help for ‘other’ commands passwd Changes the config shell password ping Pings a host. Usage: ping For example, ping 192.168.1.
6. C-75 Troubleshooting Following are the troubleshooting guidelines for C-75. Symptoms Wi-Fi: any Ethernet: fast blink Power: solid orange Diagnosis Solution The device did not receive a valid IP address via the DHCP. Ensure that the DHCP server is on and available on the VLAN/subnet to which the device is connected. If the device still fails to get a valid IP address, you can reboot it to see if the problem is resolved. The Ethernet cable is loose.
Appendix A: Access Point (AP)-Server Mutual Authentication The AP-server communication begins with a mutual authentication step in which the AP and server authenticate each other using a shared secret. The AP-server communication takes place only if this authentication succeeds. After the authentication succeeds, a session key is generated. All communication between the AP and server from this point on is encrypted using the session key.
