Power Off the Chassis

Before you remove power from the chassis, you must place the CMM in standby mode. This action removes power from all the chassis components. You can still perform Oracle ILOM commands from the CMM.

You must remove power from the system to service the following components:

• Midplane

• Internal power cables

• Fan boards

1. Log in to the Oracle ILOM CLI on the CMM.
2. Power off the chassis to standby power.

   Type:

   stop /CH

   This command powers off the server modules without a graceful shutdown of the host operating systems.

   ---

   Caution - Using the -f option could result in data loss unless the host operating systems have already been shut down at the server module level.

   ---

   For instructions on powering on the system, see Returning the Modular System to Operation.

3. Disconnect all four power cords from the back of the chassis to fully power off the chassis.

   The following figure shows the numbering of the AC connectors on the chassis.
