4.6.3.3 Powered-On or Powered-Off System
1. Carefully insert the board (component side to the right) in the proper slot in the
card cage, ensuring that the board does not slip out of the top and bottom card
guides.
All empty slots must have a filler panel installed.
2. Ensure that both extraction levers are in the insert position (arrow pointing
outward), and that the quarter-turn access slots are unlocked (arrow indicates
unlocked position) as you slide the board toward the centerplane receptacles.
The board will not seat fully unless the levers are in this starting position and the
access slots are unlocked. See
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. Push the board into the card cage, then simultaneously press both extraction
levers to seat the board on the centerplane.
Pushing both levers simultaneously avoids twisting the board and bending the
connector pins, and mates the board centerplane connector to the matching
receptacle on the centerplane. Do not press on board front panel to seat it—doing so
will damage the connector pins.
4. Mechanically lock the board to the system chassis by inserting a Phillips No. 1
screwdriver into each quarter-turn access slot and then turning to the locked
position. See
5. Replace or connect all necessary cables to the front of the board.
Note – The I/O+ board in slot 1 controls the internal media tray devices.
Therefore, the external SCSI connector on the I/O+ board in slot 1 of a system
must be terminated with a SCSI terminator. See
6. Terminate the board SCSI out connector if required. See "Note" above.
