Troubleshoot Server Module Power Problems

If the server module does not power on to either a full power or standby power state, the issue might be related to Sun Blade 6000 Chassis power limitations. Power limitations are managed by the CMM Oracle Integrated Lights Out Management (ILOM). Every time a server module attempts to power on, it queries the CMM Oracle ILOM to ensure that sufficient power is available from the chassis power supply units (PSUs). If the PSUs cannot supply enough power, the CMM Oracle ILOM prevents the server module from receiving power (standby and full), and the server module front panel OK/Power indicator blinks and does not display solid.

The chassis power supplies can only supply enough power for certain configurations of server modules and storage modules. Review the power supply and the slot configurations (the number of server modules and storage modules) of your chassis, and refer to the Sun Blade X4-2B Product Notes document for the server module and the Sun Blade 6000 Chassis for configuration information.

Use this procedure to troubleshoot server module power on issues If the server module fails to power on to a standby or full power state:

1. Log in to the CMM ILOM.
2. Review the system event log (SEL) messages.
   
3. Confirm that the server has permission to power on.

   If the chassis cannot supply adequate power to the server module, A message is generated in the SEL.

   For more information about SEL messages and power management, refer to the http://www.oracle.com/goto/x86AdminDiag/docs.

4. Ensure that the system chassis has the proper number of power supplies to support powering on all the chassis components currently installed.

   For more information about the Oracle ILOM system event log or monitoring power consumption, refer to the Oracle Integrated Lights Out Manager (ILOM) 3.1 Documentation Collection.

5. Verify that the Oracle ILOM CMM power management settings for PSUs is configured to default settings, to avoid power loss.
