3. Pull the ends of both extraction levers outward simultaneously to unseat the
board from the centerplane receptacles.
6.3.2 Installing an Interface Board
1. Carefully insert the board in the proper slot in the card cage, ensuring that the
board does not slip out of the top and bottom card guides.
The component side of the board must face to the right.
2. Ensure that both extraction levers are in the outward position as you slide the
board toward the centerplane connectors.
The board will not seat fully unless the levers are in this starting position.
Caution – DO NOT FORCE any board into a slot; this can cause damage to the
board and system. The board should insert and seat smoothly. If it binds, remove the
board and inspect the card cage slot for any obvious obstructions. Also inspect both
the board and the centerplane for bent pins or other damage.
3. Use the extraction levers to seat the board.
Simultaneously swing both levers into the locked position. Do not press on board to
seat it; doing so will damage the connector pins.
4. Secure the board to the chassis using the two captive screws.
5. Reonnect any fiber optic cables to the board front panel.
6.3.3 Removing a GBIC
Note – It is not necessary to remove the interface board from the card cage to
remove and replace GBICs. A GBIC may be removed and replaced "live" (without
removing power from the system or board). However, the necessary software
precautions must be taken whenever the I/O path to a particular disk is to be
interrupted; halt all I/O activity to the disk affected by the replacement of a GBIC.
To remove a GBIC, first remove the fiber optic cable as shown in
compress the two locking tabs while pulling the GBIC straight out as depicted in
