Identifying Compatible SCSI Cables

Make all SCSI bus connections to the A7173A adapter with shielded, 68-pin cables (multimode, LVD or SE). The connectors on the cables are keyed for proper mating.

Connecting Internal Devices

The A7173A adapter has two internal 68 pin HD connectors, one for each SCSI channel. If you purchased your A7173A adapter as a factory-integrated controller (ordered on product option 0D1), any internal SCSI devices will be connected at the factory. If an internal SCSI device has been installed on one of the A7173A adapter’s SCSI channels, do not connect any devices to the external port for that channel.

Connecting External Devices

The A7173A adapter has two external 68 pin VHDCI connectors, one for each SCSI channel. External SCSI devices, may have 68 pin HD or VHDCI connectors. No SCSI cables are shipped with the A7173A adapter.

NOTE: Auto termination is factory enabled on the A7173A adapter. External terminators can

be ordered from HP, if necessary (order SCSI LVD/SE terminator: HP product number C2370A).

To connect external SCSI devices to the A7173A adapter:

1.Plug the 68-pin VHDCI connector on one end of a SCSI cable into an external connector on the A7173A adapter. Make sure the external connector you attach the SCSI cable to corresponds to the channel you want to connect the external device to.

2.Plug the 68-pin HD or VHDCI connector on the other end of the cable into the SCSI connector on the external SCSI device.

3.If you need to connect more than one external SCSI device to the adapter, “daisy chain” them together with shielded external SCSI cables.

When you have finished connecting the external devices, go to, “Setting the SCSI Parameters” (page 23).
