Resolving a power problem

Learn how to identify the service action that is needed to resolve a power problem.
Procedure
1. Is the identify LED on the front of the system flashing red slowly at 0.25 Hz? For more information
about LEDs, see LEDs on the 9006-12P system or LEDs on the 5104-22C, 9006-22C, or 9006-22P
system.
If
Yes:
No:
2. Perform the following actions, one at a time until the problem is resolved:
a. Ensure that all of the power cords are fully seated in the power supplies.
b. Ensure that the power supply is fully seated in the system.
c. Ensure that the power supply fan is not blocked.
d. Ensure that all of the power cords are fully seated in the power distribution units (PDUs) or wall
outlets.
e. If the power cords are plugged into PDUs, ensure that the PDUs are turned on.
f. Replace the power cords.
g. Replace the power supplies.
• If your system is a 5104-22C or 9006-22C, go to "5104-22C or 9006-22C locations" on page
63 to identify the physical location and the removal and replacement procedure.
• If your system is a 9006-12P, go to "9006-12P locations" on page 75 to identify the physical
location and the removal and replacement procedure.
• If your system is a 9006-22P, go to "9006-22P locations" on page 91 to identify the physical
location and the removal and replacement procedure.
This ends the procedure.

Resolving a system firmware boot failure

Learn how to identify the service action that is needed to resolve a failure while booting your system
firmware.
Procedure
1. Does the baseboard management controller (BMC) respond to commands and are you able to access
the BMC web interface?
Note: To determine whether the BMC responds to commands, run the following ipmitool command:
ipmitool -I lanplus -U <username> -P <password> -H <bmc ip or bmc hostname> chassis status
If
Yes:
No:
2. Complete the following actions, one at a time, until the problem is resolved:
a. Reset the BMC remotely by entering the following command:
Then
Continue with the next step.
No service action is required. This ends the procedure.
Then
Continue with step "3" on page 6.
Continue with the next step.
