FRU Removal and Replacement 8-45
Removing the PCI Backplane
CAUTION: When removing the PCI backplane, be careful not to flex the board.
Flexing the board may damage the BGA component connections.
1.
Remove the 12 screws ➊ that secure the PCI backplane to the chassis.
CAUTION: Do not remove the four additional nonwashered screws
➋.
Removing them inactivates the built-in mechanism for
extracting the PCI backplane from the system.
2.
Use the ejector lever ➌ in the fan area to separate the PCI backplane from
the system motherboard, then lift the backplane out of the chassis.
NOTE: When installing a new PCI backplane, align the backplane on the guide
pins ➍, and press the board firmly until it is seated. Seating the PCI
backplane requires considerable pressure. When seating the PCI
backplane in a cabinet, a second person should brace the chassis to
ensure that no excessive stress is placed on the rails.
