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 on page 5-7.

5.Replace or connect all necessary cables to the front of the board.

6.Terminate the SCSI out connector if necessary.

The SCSI out connector on Disk boards in a system, which are not daisy chained to an additional device, must be terminated with a SCSI terminator. See Figure 5-3 on page 5-4.

Note – The last or only Disk board in a system must have the SCSI out connector terminated with a fast-wide SCSI terminator, part number 150-2267.

7.Once the 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.

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