Opening the Xserve
Loosen the thumbscrews at the back of the top cover and slide the cover back and up to remove
it. If you have difficulty removing the cover, check the enclosure lock on the front panel.
Warning: Even after you shut down the Xserve, its internal components can be very hot. Let
it cool before you open it.

wear an antistatic wrist strap, if possible, while you work inside the Xserve.
Unscrew the two
captive thumbscrews.
Slide the cover back and lift it off.
