Chapter 5. Installing and replacing components
This chapter provides instructions to help you install or remove customer
replaceable units (CRUs), such as hot-swap drives, fans, RAID controllers, and
power supplies.
For more field-replaceable unit (FRU) and Option part number information, see the

Handling static-sensitive devices
Attention: Static electricity can damage electronic devices and your system. To
avoid damage, keep static-sensitive devices in their static-protective packages until
you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
v Limit your movement. Movement can cause static electricity to build up around
you.
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed printed circuitry.
v Do not leave the device where others can handle and possibly damage the
device.
v While the device is still in its static-protective package, touch it to an unpainted
metal part of the storage server for at least two seconds. This drains static
electricity from the package and from your body.
v Remove the device from its package and install it directly into your storage
server without setting it down. If it is necessary to set the device down, place it in
its static-protective package. Do not place the device on your storage server
cover or any metal surface.
v Take additional care when handling devices during cold weather because heating
reduces indoor humidity and increases static electricity.
Working with hot-swap drives
Drives are devices that the system uses to store and retrieve data. This section
explains how you can increase the storage-server capacity by adding more drives
or replacing existing drives with ones containing a larger capacity.
Figure 39 on page 46 shows the location of the hot-swap drive bays that are
accessible from the front of the storage server. To maintain proper cooling within the
storage server, always keep a filler panel in each drive bay that does not contain a
drive CRU.
