Chapter 4. Customer replacement units

This chapter provides basic instructions for installing hardware options in the server.
These instructions are intended for users who are experienced with setting up IBM
server hardware.

Installation guidelines

v Have a small flat-blade screwdriver available.
v You do not have to turn off the server to install or replace hot-swap drives or
v Blue on a component indicates touch points, where you can grip the component
v Orange on a component or orange label on or near a component indicates that
v When you need to access the inside of the server to install options, you might

System reliability guidelines

To help ensure proper cooling and system reliability, make sure that:
v Each of the drive bays has a drive or a filler panel and electromagnetic
v There is adequate space around the server to allow the server cooling system to
v You have followed the cabling instructions that come with optional adapters.
v You have replaced a failed fan as soon as possible.
v You have replaced a hot-swap drive within 2 minutes of its removal.
v You do not remove the air baffle when the server has power or is running.

the component can be hot-swapped, which means that if the server and
operating system support hot-swap capability, you can remove or install the
component while the server is running. (Orange can also indicate touch points on
hot-swap components.) See the instructions for removing and installing a specific
hot-swap component for any additional procedures that you might have to

and rear of the server. Do not place objects in front of the fans. For proper
cooling and airflow, replace the server cover before turning on the server.
Operating the server for extended periods of time (more than 30 minutes) with
the server cover removed might damage server components.
