The following table shows the pin-number assignments for
the connector used by the keyboard port.
Auxiliary-device (pointing device) port:
The
system board has one auxiliary-device port that supports a
mouse or other pointing device. (See “Input/output
connectors and expansion slots” on page 91 for the
location of the connector.)

The following table shows the pin-number assignments for
the connector used by the auxiliary-device port.
SCSI ports:
The server comes with a LVD SCSI
controller on the system board, which provides two
independent SCSI channels. A 16-bit (wide) SCSI cable
connects the hot-swap backplane to one channel of the
integrated LVD SCSI controller. Another SCSI cable
connects the other channel of the controller to the SCSI
connector on the rear of the server.
To attach an external SCSI device to the server, connect
an external SCSI cable from the SCSI device to the SCSI
connector on the back of the server. Ensure that the last
device on the external SCSI cable is terminated.
