2.3 Connecting to Host

The subsystem supports the Ultra 320 SCSI LVD interface which provides fast 320MB/S data transfer rates using a 16-bit SCSI bus. Installation of the disk array is very similar to the installation of a standard SCSI drive. The SCSI connector accepts the standard 68-pin LVD SCSI connector used on most LVD SCSI devices. Refer to your system and/or SCSI host adapter manual for additional installation procedures that may apply to your system or host adapter.

1.The package comes with two external SCSI cables. For every pair of host channel SCSI connector at the rear of the subsystem, attach one end of the external SCSI cable to one of the SCSI connectors and the other end to the host adapter’s external SCSI connector. (The host adapter is installed in your Host subsystem.)

2.Connect the other host system using the other external SCSI cable if you want to configure subsystem into multi-host attachment.

Note:

!1. When one or more SCSI devices are connected, the total length of all cables (internal or external) must not exceed 3 meters (9.8 ft.) to ensure reliable operation.

2. For safety reasons, make sure the Disk Array and Host Com- puter are turned off when you plug-in the SCSI cable.
