Chapter 10. Installing and replacing components

This chapter provides instructions for installing and replacing hardware components
in the storage subsystem.

Installation guidelines

Before you begin installing options, read the following information:
v Read the safety information beginning on page iii and the guidelines in "Handling
v Make sure that you have an adequate number of properly grounded electrical
v Back up all important data before you make changes to disk drives.
v Have a small flat-blade screwdriver available.
v You do not have to turn off the storage subsystem to install or replace a hard
v Blue on a component indicates touch points, where you can grip the component
v Orange on a component or an orange label on or near a component indicates
v For a list of supported options for the storage subsystem, see

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 If the storage subsystem has redundant power, each of the power-supply bays
v There is adequate space around the storage subsystem to allow the storage
v You have replaced a failed power supply within 10 minutes of removal.
v You have replaced a hot-swap drive within 2 minutes of removal.

Handling static-sensitive devices

Attention:
To avoid damage, keep static-sensitive devices in their static-protective packages
until you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the
following precautions:
v Limit your movement. Movement can cause static electricity to build up around

that the component can be hot-swapped, which means that you can remove or
install the component while the storage subsystem is running. (Orange can also
indicate touch points on hot-swap components.) See the instructions for removing
or installing a specific hot-swap component for any additional procedures that
you might have to perform before you remove or install the component.
