Closing the cover and connecting the cables
After replacing a FRU, you need to install any removed parts, close the cover, and
reconnect cables, including telephone lines and power cords. Also, depending on
the FRU that is installed, you might need to confirm the updated information in
the IBM Setup Utility program.

To close the cover and connect cables to the computer:

1. Ensure that all components have been reassembled correctly and that no tools
or loose screws are left inside the computer.
2. Clear any cables that might impede the replacement of the cover.
3. Make sure that the drive locks are both in the locked position. Otherwise, you
cannot close the cover.
4. Close the cover.
5. If a cover lock is installed, lock the cover.
6. If the computer is being placed in the vertical position, attach the floor stand.

Attention: To prevent overheating and possible component damage, always

attach the floor stand when placing the computer in the vertical position.
7. Reconnect the external cables and power cords to the computer. See “Locating
connectors on the rear of the computer” on page 24.
8. If you have replaced the system board, you must update (flash) the BIOS. See
“Flash update procedures” on page 148.
9. To update the configuration, see “Starting the IBM Setup Utility program” on

page 19.
