another person.
Tools Required
The only tool required for this procedure is a Phillips screwdriver.
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.
