SCSI Connection Examples

This is an example of how SCSI devices can be connected to your server.

•Two 9GB Ultra2-SCSI hard disks in the 3.5” cage can be connected to the Ultra2 connector on the motherboard for 18GB of main storage.

•One Ultra-SCSI tape drive in the 5.25” cage is connected to the 50 pin narrow connector on the motherboard for routine backups.

•The Wide-SCSI connector on the motherboard can be extended (using an optional SCSI cable with external bracket) to the chassis slot opening for connection of an external 4GB Ultra-Wide Hard disk drive and a Wide-SCSI CD recorder for archives.

You must terminate the SCSI cable even if no devices are connected. Either place a terminator here or remove the SCSI cable from the motherboard. This holds true for each unused SCSI cable.
