be sure to wait a brief period to allow the server’s internal components to cool.
warning always shut down your server before opening it to avoid damaging its internal components or the components you want to install. do not open the server or attempt to install items inside it while it is turned on. after shutting down your server, the internal components can be very hot. let the computer cool down before continuing.
2 if the cable-management arm is not in use for all cables, unplug all cables from the back panel except the power cord. (if necessary, also remove the firewire cable from the front panel.)
3 touch the metal enclosure to discharge any static electricity.
4 unplug the power cord.
important always do this before you touch any parts, or install any components, inside the computer. to avoid generating static electricity, do not walk around the room until you have finished installing the expansion card, memory, or internal storage device and have closed the computer.
warning the power supply in your computer is a high-voltage component and should not be opened for any reason, even when the computer is off. if the power supply needs service, contact your apple-authorized dealer or service provider.
5 loosen the thumbscrews at the front of the server’s cover.
6 grasp the thumbscrews and use them to slide the server forward.
the server’s cover remains in place. the enclosure and components slide forward until the interior is in view.
if you need to remove the server from the rack, press the release latches on each side of the server’s interior, then carefully slide it forward and lift it out of the cover.
7 when you’ve completed your work inside the server, carefully slide it closed and tighten the front thumbscrews to secure it in the rack.
