2. Turn off the server and all attached devices; then, disconnect all power cords
and external cables.
3. Unlock and remove the side cover (see “Removing the side cover” on page 43).
4. Disconnect any cables from the adapter or any cables that impede access to
the adapter.
5. Rotate the rear adapter retention bracket to the open (unlocked) position. If you
are removing a full-length adapter, open the front adapter-retention bracket also.
6. If necessary, remove the expansion-slot screw at the rear of the adapter.

adapter from the server.
Attention: Expansion-slot covers must be installed in all empty slots. This
maintains the electronic emissions standards of the computer and ensures
proper ventilation of computer components.
