Connecting an External SCSI Bus

You can use the wide (68-pin) or narrow (50-pin) SCSI connector on the main logic board to connect

external SCSI devices to the server.

NOTE

The External Onboard SCSI field in the BIOS Setup must be set to Enabled.

To connect an external SCSI bus, follow these instructions:

1) Connect the 68-pin or 50-pin cable connector to the corresponding connector on the main logic

board.

2) Decide which SCSI knockout is needed. The top SCSI knockout is for a narrow 50-pin connector.

3) The bottom SCSI knockout is for a wide 68-pin connector (see Figure 3 - 31).

4) Using a screwdriver, gently pry away one of the external SCSI knockouts located at the rear of the

server.

5) Screw the external SCSI connector to the rear panel with the screws provided.

6) Connect the external device making sure the SCSI bus is properly terminated.

7) When using a wide external SCSI connector, set the wide SCSI jumper (J22) on the main logic board

to Enabled.

8) Run the SCU and any other SCSI utilities to configure the server.
