Completing the FRU replacement.
After replacing FRUs, you need to install any removed parts, replace the cover, and
reconnect any cables, including telephone lines and power cords. Also, depending
on the FRU that is replaced, you might need to confirm the updated information in
the Setup Utility program.

Note: When the power cord is first plugged in, the computer might appear to turn

on for a few seconds and then turn off. This is a normal sequence to enable
the computer to initialize.
1. Ensure that all components have been reassembled correctly and that no tools
or loose screws are left inside your computer.
2. Make sure the cables are correctly routed and are retained by the cable clips.
3. Lower the drive bay assembly.
4. Close the cover.
5. If your 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.
6. Reconnect the external cables and power cords to the computer. See “Locating
connectors on the front” on page 89 and “Locating the connectors on the rear”
on page 90.
7. If you have replaced the system board, you must update (flash) the BIOS. See
“Flash update procedures” on page 150.
8. Some FRU replacements rquire the configuration to be updated. See Chapter 6,
