Installing a computer wall mount
For information about how to install a computer wall mount, see the documentation that came with your
computer wall mount.
Note:
When installing a computer wall mount, make sure that you leave at least a 60 mm (2.36 inches) space
between the wall and your computer for easy access to the connectors on the rear I/O assembly.
Completing the FRU installation
After replacing FRUs, you need to install any removed parts, replace the computer cover, and reconnect any
cables, including telephone cords 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 for the computer to initialize.
Installing a computer cover
To install a computer cover, do the following:
1. Replace the two rubber tabs you had previously removed.
2. Replace the cover so that the slots on the top edge of the computer cover align with the tabs on the
computer.
