Component Service Categories
The server components and assemblies that can be replaced in the field fall into three
categories:
-
Hot-service, replaceable by customer
-
Cold-service, replaceable by customer
-
Cold-service, replaceable by authorized service personnel
Cold service procedures require that you shut the server down and unplug the power
cables that connect the power supplies to the power source.
Although hot service procedures can be performed while the server is running, you
should usually bring it to standby mode as the first step in the replacement procedure.
Refer to Power Off the Server (Server Power Button - Graceful) for instructions.
