• Problem: The least priority servers lost power after a PSU failure.
– Resolution: This is expected behavior if the enclosure power policy was configured to No Redundancy.
To avoid a future power supply failure causing servers to power off, ensure that the chassis has at least
four power supplies and is configured for the Power Supply Redundancy policy to prevent PSU failure
from impacting server operation.
• Problem: Overall server performance decreases when the ambient temperature increases in the data center.
– Resolution: This can occur if the System Input Power Cap has been configured to a value that results in
an increased power need by fans having to be made up by reduction in the power allocation to the
servers. User can increase the System Input Power Cap to a higher value that allow for additional power
allocation to the fans without an impact on server performance.

Troubleshooting Alerts

Use the CMC log and the trace log to troubleshoot CMC alerts. The success or failure of each e-mail and/or SNMP trap
delivery attempt is logged into the CMC log. Additional information describing the particular error is logged in the trace
log. However, since SNMP does not confirm delivery of traps, use a network analyzer or a tool such as Microsoft's
snmputil to trace the packets on the managed system.

Viewing Hardware Log
CMC generates a hardware log of events that occur on the chassis. You can view the hardware log using the Web
interface and remote RACADM.
NOTE: To clear the hardware log, you must have Clear Logs Administrator privilege.
NOTE: You can configure CMC to send e-mail or SNMP traps when specific events occur. For information on
configuring CMC to send alerts, see
