Remove the Motherboard
9.
Remove the power supply cover (panel 1).
You must guide two slots on the PS backplane cover around two pins on the inside of the power
supply cage.
a.
Lift the cover up a little to clear the first part of the slots.
b.
Pull the cover a little towards the front of the chassis.
c.
Push the tooth at the bottom of the cover to clear the edge of the power
supply cage.
d.
Lift the cover out of the chassis.
Notice the two cables that are now exposed. Be prepared to move those cables out of the
way when you lift the motherboard.
10.
Remove the four bus bar screws that secure the motherboard to the PS
backplane.
See “Remove the PS Backplane” on page 163.
11.
Position the drive end of the cables off to the side using the tab on the top of the
plastic power supply cover.
