The following table shows the pin-number assignments for the connector used by the keyboard port. Table 5. Keyboard port pin-number assignments Pin Signal 1 Keyboard data 2 Mouse data 3 Ground 4 +5 V dc 5 Keyboard clock 6 Mouse clock 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.) 6 5 4 3 2 1 The following table shows the pin-number assignments for the connector used by the auxiliary-device port. Table 6. Auxiliary-device port pin-number assignments Pin Signal 1 Data 2 Not connected 3 Ground 4 +5 V dc 5 Clock 6 Not connected 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. 150 Netfinity Server HMM
