and then press <Enter>. Sample prompts:
recover1[self test] CMC 1 self test failure
recover2[Bad FW images] CMC2 has corrupted images
• If the prompt indicates a self test failure, there are no serviceable
components on CMC. CMC is bad and must returned to Dell.
• If the prompt indicates
Bad FW Images , then follow the steps in
"Recovering the Firmware Image" on page 412 to fix the problem.
Recovering the Firmware Image
CMC enters recover mode when a normal CMC OS boot is not possible. In
recover mode, a small subset of commands are available that allow you to
reprogram the flash devices by uploading the firmware update file,
firmimg.cmc. This is the same firmware image file used for normal firmware
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
recover ping 192.168.0.100
recover fwupdate -g -a 192.168.0.100
NOTE: Connect the network cable to the left most RJ45
NOTE: In recover mode, you cannot ping CMC normally because there is no active
network stack. The recover ping <TFTP server IP> command allows you to ping to
the TFTP server to verify the LAN connection. You may need to use the recover
reset command after setniccfg on some systems.
