- Frequently Asked Questions
○ Resolution A: This configuration requires at least one power supply in side 1 (the left two slots) and one power supply in side 2
(the right two slots) to be present and functional in the modular enclosure. Additionally the capacity of each side must be enough
to support the total power allocations for the chassis to maintain Grid redundancy. (For full Grid Redundancy operation, make
sure that a full PSU configuration of four power supplies is available.)
○ Resolution B: Check if all power supplies are properly connected to the two AC grids; power supplies in side 1 must be connected
to one AC grid, those in side 2 must be connected to the other AC grid, and both AC grids must be working. Grid Redundancy is
lost when one of the AC grids is not functioning.
• Problem: The PSU state is displayed as Failed (No AC), even when an AC cord is connected and the power distribution unit is
producing good AC output.
○ Resolution A: Check and replace the AC cord. Check and confirm that the power distribution unit providing power to the power
supply is operating as expected. If the failure still persists, call Dell customer service for replacement of the power supply.
○ Resolution B: Check that the PSU is connected to the same voltage as the other PSUs. If CMC detects a PSU operating at a
different voltage, the PSU is turned off and marked Failed.
• Problem: Dynamic Power Supply Engagement is enabled, but none of the power supplies display in the Standby state.
○ Resolution A: There is insufficient surplus power. One or more power supplies are moved into the Standby state only when the
surplus power available in the enclosure exceeds the capacity of at least one power supply.
○ Resolution B: Dynamic Power Supply Engagement cannot be fully supported with the power supply units present in the
enclosure. To check if this is the case, use the web interface to turn Dynamic Power Supply Engagement off, and then on again. A
message is displayed if Dynamic Power Supply Engagement cannot be fully supported.
• Problem: Inserted a new server into the enclosure with sufficient power supplies, but the server does not power on.
○ Resolution A: Check for the system input power cap setting—it might be configured too low to allow any additional servers to be
powered up.
○ Resolution B: Check for the maximum power conservation setting. If this is set, then this issue occurs. For more details, see the
power configuration settings.
○ Resolution C: Check for the server slot power priority of the slot associated with the newly-inserted server, and then ensure it is
not lesser than any other server slot power priority.
• Problem: Available power keeps changing, even when the modular enclosure configuration has not changed.
○ Resolution: CMC has dynamic fan power management that reduces server allocations briefly if the enclosure is operating near
the peak user configured power cap; it causes the fans to be allocated power by reducing server performance to keep the input
power draw below System Input Power Cap. This is normal behavior.
• Problem: <number>W is reported as the Surplus for Peak Performance.
○ Resolution: The enclosure has <number>W of surplus power available in the current configuration, and the System Input Power
Cap can be safely reduced by this amount being reported without impacting server performance.
• Problem: A subset of servers lost power after an AC Grid failure, even when the chassis was operating in the Grid Redundancy
configuration with four power supplies.
○ Resolution: This can occur if the power supplies are improperly connected to the redundant AC grids at the time the AC grid
failure occurs. The Grid Redundancy policy requires that the left two power supplies be connected to one AC grid, and right two
power supplies be connected to other AC grid. If two PSUs are improperly connected, such as PSU 2 and PSU 3 are connected to
the wrong AC grids, an AC grid failure cause loss of power to the least priority servers.
• Problem: The least priority servers lost power after a PSU failure.
○ Resolution: To avoid a future power supply failure causing servers to power off, make sure that the chassis has at least three
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 email 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.
