Chapter 3. Replacing the FAStT900 Storage Server
components
The FAStT900 Storage Server contains two RAID controllers, a cooling system that
contain four fans, mini hubs, SFP modules, and a power system. This chapter
includes detailed instructions on how to replace these components.
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 package 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 system unit 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 system unit
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 system unit cover or
on a metal table.
v Take additional care when handling devices during cold weather because heating
reduces indoor humidity and increases static electricity.
FAStT900 Storage Server controller
The FAStT900 Storage Server supports RAID technology. The FAStT900 Storage
Server contains two RAID controllers.
Each controller comes in a removable, portable unit, called a controller CRU, as
shown in Figure 34 on page 39. Each controller CRU slides into one of two
controller slots on the front of the FAStT900 Storage Server and attaches to hosts
through Fibre Channel connections. Two handles lock the controller in place. Each
controller slot has a controller slot designation that identifies the physical location of
the controller in the chassis: controller slot A (top) or controller slot B (bottom). Each
controller CRU has ten indicator lights: one power, one fault, and eight status
indicator lights, as shown in Figure 33 on page 38.
