Owner's Manual

If the prompt indicates a self test failure, there are no serviceable components on CMC. Then, replace the CMC

card.

If the prompt indicates Bad Firmware Images, then recover the firmware image:

a. At the recover prompt, type recover and then press <Enter>. The recover reason and available sub-

commands are displayed.

b. Run the following commands to reprogram the flash devices by uploading the firmware update file

firmimg.cmc:

recover getniccfg

recover setniccfg <IP address> <Subnet address> <Gateway address>

recover ping <

IP address>

recover fwupdate -g -a <IP address>

NOTE: This is the same firmware image file that is used for normal firmware updates.

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.

The recovery process displays its current activity and boots to the CMC OS upon completion. 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: Make sure CMC has the latest revision firmware. To check the CMC version, from Telnet/SSH use the

racadm getversion command or on the CMC Web interface, go to Chassis Overview → Update.

To get the latest CMC firmware visit the Dell Support site at Support → Drivers & Downloads → Enterprise IT

→ Servers, Storage & Networking → Poweredge → Poweredge M1000E → Chassis System Management →

Dell firmware.

Power Supply Unit Not Detected

1. Make sure that all the Power Supply Units (PSUs) are firmly connected to the chassis and status for each PSU is

either online or standby. Check and replace the AC or DC cord if needed. Check to confirm the power distribution

unit providing power to the PSU is operating normally.

2. Make sure that all the PSUs are operating at the same voltage. Use external tools to check and correct the voltages

for the PSUs.

3. If the problem persists, perform one of the following:

– If you are able to access or ping the CMC IP address, log in to CMC though the Web interface or RACADM

(Telnet/SSH, Remote, or Serial RACADM) interface.

– If you log in to CMC through the Web interface, go to Chassis Overview → Troubleshooting → Reset

components and click Reset/failover CMC.

– If you log in to CMC through RACADM (Telnet/SSH/Serial), run the racadm cmcchangeover command. This

command is applicable only if the M1000e chassis has two CMCs, one active and the other standby. If there

is only one CMC in the M1000e chassis, run the racadm racreset command.

– If you log in using remote RACADM and if the chassis has two CMCs (one active and the other standby),

run the following command:

racadm -r<CMC IP address>-u<username>-p<password>cmcchangeover

It takes around five minutes for the CMC to reboot. Log in to CMC through the Web interface or RACADM

(Telnet/SSH/Serial) using the IP address and view the active errors in the CMC logs.
