Remove a Power Supply
-
Identify which power supply requires replacement; either PS0 [1] or PSU1 [2].
A lit amber Service Required LED on a power supply indicates that a failure was detected. You can also use the Oracle ILOM show faulty command at the Oracle ILOM prompt (->) to identify a power supply failure.
Alternatively, to list all known faults in the server, log into the Oracle Solaris OS and issue the fmadm faulty command, or log into the Oracle ILOM service processor from the Oracle ILOM Fault Management Shell and issue the fmadm faulty command.
Note - The fans of a failed power supply might still be spinning when the system is powered on. The fans will stop spinning when you disconnect the power cords. - Gain access to the rear of the server where the faulty power supply is located.
-
Disconnect both cable management arm (CMA) left-side connectors and move the
CMA out of the way.
For instructions for disconnecting the CMA left-side connectors, see Remove the Cable Management Arm in Oracle Exadata Storage Server X6-2 High Capacity Installation Guide.
Caution - When disconnecting the CMA left-side connectors, be sure to use your arm to support the CMA so that it does not hang down under its own weight and stress the right-side connectors; otherwise, the CMA might be damaged. You must continue to support the CMA until you have reconnected both of the left-side connectors.
- Disconnect the power cord from the faulty power supply.
-
Grasp the power supply handle and push the power supply latch to the left [1].
-
Pull the power supply out of the chassis [2].
Caution - Whenever you remove a power supply, you should replace it with another power supply; otherwise, the server might overheat due to improper airflow.
