Drive filler

you complete cold-servicing, ensure that all fillers are in place before connecting the server to
power.

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)” on page 53 for instructions.
