Removing an adapter
To remove an adapter, complete the following steps.
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 95.
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
100).
4. Disconnect any cables to the adapter or any cables that impede access to the
adapter.
5. Open the rear adapter-retention bracket retention clip and rotate the retention
brackets to the open (unlocked) position. If you are removing a full-length
adapter, open the front adapter-retention bracket also.
6. Remove the expansion-slot screw at the rear of the adapter (if screws were
used).
7. Carefully grasp the adapter by its top edge or upper corners, and pull the
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.
