Replacement Instructions

Follow the instructions in this sheet carefully. Failure to follow these instructions could

damage your equipment and void its warranty.

Online instructions covering customer-installable parts are available at

Important:

Due to the weight of the Xserve RAID unit, two people are necessary for

moving it out of or into a rack. Do not attempt to lift or move the system without help from

another person.

Tools Required

The only tools required for this procedure are a Phillips screwdriver and either a flat-blade

screwdriver or needlenose pliers.

Opening Xserve RAID

To open Xserve RAID, you must first shut down the system and remove the unit from its

rack.

1. Alert users that the Xserve RAID drives will be unavailable for a period of time.

2. If the unit is in the locked position (the yellow security LED on the front panel is on),

use the Allen key that came with the system to unlock it.

3. Shut down the system.

Warning: After you shut down Xserve RAID, internal components can be very

hot. Let the unit cool down a few minutes before continuing.

4. Unplug all external cables except the power cords.

5. Touch the Xserve RAID metal case to discharge static electricity.

Important:

Always ground yourself by touching the case before you touch any parts

or install any components inside the unit. To avoid static electricity building back up in

your body, do not walk around the room until you have completed your work and

closed the unit.

6. Unplug the power cords.
