server from the electrical outlet. If your server includes two power supplies,
ensure that both power cords are disconnected from the electrical outlet.
Refer to “Powering Off the Server and Removing the Cover” on page 4-2.
It is not necessary to remove the cover for this procedure.

on each side of the bezel, then swinging the bezel top downward (see

3. Open the CPU card door, which is located under the hard drive bays, to access the
CPU card. Press in the two buttons on the door and swing it downward so that it
is open 180 degrees from the closed position (see
FIGURE 4-16).
