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.
