							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 the computer. 
2. 
 
 Replace the covers that were removed and secure them with the thumb screws. 
3. 
 
 Reconnect the external cables and power cords to the computer. See “Rear 
connectors” on page 84. 
4. 
 
 If you have replaced the system board, you must update (flash) the BIOS. See 
“Flash update procedures” on page 207. 
5. 
 
 Some FRU replacements require the configuration to be updated. See Chapter 6, 
“Using the Setup Utility,” on page 51.

							Chapter 9. Replacing FRUs (Types 7390, 7391, 7392, 7396, 
7397, and 7398) 
 
Important 
Before you replace any FRU, read Chapter 2, “Safety information,” on page 3. 
These precautions and guidelines will help you work safely.
 FRU replacements are to be done by trained service technicians only. 
This chapter does not contain a remove and replace procedure for all FRUs. Only 
the major FRUs are documented. 
Note:   The computer might look slightly different than the illustrations in this 
chapter.
