Troubleshooting Non-responsive CMC
If you cannot log in to CMC using any of the interfaces (the web interface, Telnet, SSH, remote RACADM, or serial), you can verify
the CMC functionality observing the LEDs on CMC, obtaining recovery information using the DB-9 serial port, or recovering the
CMC rmware image.
Observing LEDs to Isolate the Problem
The CMC has an LED which changes color to indicate:

Color Description
Blue Normal operation
Blue, blinking ID (0.5 second on, 0.5 second o)
Amber Chassis fault summary
Amber, blinking Chassis fault with concurrent ID
Obtain Recovery Information from DB-9 Serial Port
If the CMC LED is amber, recovery information is available from the DB-9 serial port located on the front of CMC.
To obtain recovery information:
1. Install a NULL modem cable between a CMC system and a client system.
2. Open a terminal emulator of your choice (such as HyperTerminal or Minicom). Enter the following specication when prompted:
8 bits, no parity, no ow control, baud rate 115200.
A core memory failure displays an error message every 5 seconds.
3. Press the <Enter> key.
If a recovery prompt appears, additional information is available. The prompt indicates the CMC slot number and failure type.
To display failure reason and syntax for a few commands, type recover, and then press <Enter>.
Sample prompts:
recover1[self test] CMC self test failure
recover1[Bad FW images] CMC has corrupted images
• If the prompt indicates a self test failure, there are no serviceable components on CMC. CMC is bad and must be returned
to Dell.
• If the prompt indicates Bad FW Images, complete tasks in Recovering Firmware Image1.
Recovering Firmware Image
CMC enters recover mode when a normal CMC operating boot is not possible. In recover mode, a small subset of commands are
available that allow you to reprogram the ash devices by uploading the rmware update le, fx2_cmc.bin. This is the same rmware
image le used for normal rmware updates. The recovery process displays its current activity and boots to the CMC OS upon
completion.
When you type recover and then press <Enter> at the recovery prompt, the recover reason and available sub-commands display. An
example recover sequence may be:
recover getniccfg
recover setniccfg 192.168.0.120 255.255.255.0
192.168.0.1
