1. Remove the two screws that secure the board to the card cage.
Set the screws aside for later use.
2. Pull the curved ends of injector/ejector levers outward to release the
board from the backplane connectors.
See Figure 7-29.
3. Gently pull the board out of the card cage.
4. Place the board on the ESD mat or in an antistatic bag.
To reinstall a system board, proceed as follows:
Note – To select a card cage slot for the system board, refer to Appendix E,
"General Rules for System Configuration."
1. Open the protective packaging and take out the system board.
2. Carefully insert the board in the proper slot in the card cage.
The component side of the board must face to the right.
Caution – Do not allow components on either side of the board to scrape
!
against other boards. DO NOT FORCE any board into a slot. If the board
binds, remove it and inspect the card cage slot for any obvious obstructions.
Also inspect both the board and the backplane for bent pins or other damage.
3. Ensure that the injector/ejector levers are in the outward position as you
slide the board toward the backplane connectors.
See Figure 7-29. The board will not seat fully unless the levers are in this
starting position.
4. Use the injector/ejector levers to seat the board.
Swing the injector/ejector levers into the locked position. Do not press on
the board to seat it—doing so will damage the connector pins.
5. Install two 2-56 Allen screws to secure the board to the card cage.
Connect any applicable interface cables to the system board back panel.
