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
conrm the updated information in the Setup Utility program.
Note: When the power cord is rst 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. Replace the cover.
3. Reconnect the external cables and power cords to the computer. See "Rear connectors" on page 67.
4. If you have replaced the system board, you must update (ash) the BIOS. See "Flash update procedures"
on page 467.
5. Some FRU replacements require the conguration to be updated. See Chapter 6 "Using the Setup
Utility" on page 39.
