HP xw6000 manual Using the Multi-Mode Scsi Cable

SCSI Devices

■68-pin SCSI controllers require a 53 inch maximum length-twisted pair, LVD cable with built-in terminator, maximum of 5 drives with a minimum driving spacing of 5.25 inches.

■Every SCSI chain or circuit must be terminated (closed) at both ends. Some system boards have both ends of the SCSI cable connected to, and terminated by, the system board. Termination can be accomplished in one of several ways:

❏Use a cable with a built-in terminator.

❏Use a cable with a terminating resistor plug in the last connector.

❏Connect a SCSI device with its termination enabled into the last connector.

❏Connect an external SCSI device with its termination enabled to the external SCSI connector on the rear panel of the computer.

■Turn on all external SCSI devices before turning on the power to the computer. This enables the SCSI controller to recognize the external devices.

5.2Using the Multi-Mode SCSI Cable

Some products ship standard with a multi-mode SCSI cable having a terminator 1 on one end. This cable supports both low voltage differential (LVD) and single ended (SE) devices. One end of the cable connects to the internal LVD/SE connector on the system board, with the remaining connectors used on the hard drives.
