To remove an adapter on the 5U server model with hot-swap power supplies,
complete the following steps. For 4U server models with non-hot-swap power
supplies, please see the above sub-section.
1. Read the safety information in “Safety” on page vii and “Installation
guidelines” on page 35.
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 38).
4. Carefully turn the server on its side so that it is lying flat, with the system
board facing up. Do not allow the server to fall over.
Attention: Do not allow the server to fall over.
5. Disconnect any cables from the adapter or any cables that impede access to the
adapter.
6. Rotate the rear adapter-retention bracket to the open (unlocked) position.
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.
8. If you are not replacing the adapter, install an expansion-slot cover in the
expansion-slot opening.
9. If you are instructed to return the adapter, follow all packaging instructions,
and use any packaging materials for shipping that are supplied to you.
