Troubleshooting Steps
1. AC must be present. Check that
PDU is plugged in.
2. Ensure there is a working
power supply. The LED on the
supply should be lit.
3. Check for an EFI shell prompt
(CTRL B) at console).
1. Ensure there is a working
power supply. The LED on the
supply should be lit.
2. Verify that standby voltage is
present. Check that the STBY
LED on the system board is lit.
3. Verify that the baseboard
management controller is
functioning. Check the
heartbeat (BMC) LED on the
system board is lit.
4. Check server event log (SEL).
Look for event log detail = Low
Voltage DC power. This
indicates a failure of one of the
CPU power pods.
1. Check that the console is
properly connected and can
communicate with the BMC.
Press (CTRL B) to access the iLO
MP login prompt.
2. Check SEL.
Look for entries related to:
• Processors
• Processor Support Modules
(Also known as power pods).
• Memory
3. Check for red LED on the iLO
MP card if installed. If red, the
problem is with the iLO MP.
4. Reduce to minimum
configuration and troubleshoot
from there.
1. Check console messages. Did
server hang?
2. Check SELs for possible
problem indication.
3. Run ODE diagnostics.
