Sun Enterprise 6500/5500/4500 Systems Reference Manual

Inserting a System Board

  1. Carefully insert the board (component side down if in front; component side up if in the rear) in the proper slot in the card cage, ensuring that the board does not slip out of the left and right card guides (Figure 5-7).

    Figure 5-7 Board Replacement


  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.

    See Figure 5-4 and Figure 5-5. The board will not seat fully unless the levers are in this starting position and both quarter-turn access slots are unlocked.

    Caution - 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 #1 screwdriver into each quarter-turn access slot and then turning to the locked position.

    See Figure 5-4.

  5. Connect the Disk board to a SCSI Host Adapter (on-board or SBus card).

    The Disk board kit includes an 80-cm fast-wide SCSI cable. If the Disk board is installed on the opposite side of the card cage from the SCSI Host Adapter, you must use a 2-meter cable, part number 530-1885 (sold separately).

  6. If the Disk board is the last (or only) board in the SCSI chain, terminate the SCSI out connector on the disk board.

    The Disk board kit includes a fast-wide SCSI terminator, part number 150-2267.

  7. Replace or connect all other necessary cables to the fronts of the boards.

  8. Once the Disk board has been installed, a message similar to the following will be displayed on the monitor (if the system is powered on):

    Example depicts screen output when a new Disk board has been hot-plugged into slot 6 of an operating Enterprise system:

    NOTICE: Disk Board Hotplugged into Slot 6
    NOTICE: Board 6 is ready to remove

    This screen output indicates that the board has been detected by the system and is in the low power mode. Additionally, any subsequent prtdiag(1M) output would include information for board slot 6. Again, note that the system will not use the new board until the system is rebooted.

  9. Reboot the system now or schedule a later time to reboot when system disruption will be minimized.
