NOTE Using Your Personal Workstation Connecting SCSI Accessories While SE SCSI devices will work when attached to connector 1 or 2, this will limit all devices to single-ended mode. For example, this would result in the Ultra 160/m hard disk drive performance being limited from 160 MB/second to 40 MB/second. Therefore, it is recommended that you connect only LVD SCSI devices to connectors 1 and 2. Connecting an External SCSI Accessory The intended use of the external SCSI connector is to connect Low-Voltage Differential SCSI devices to your Personal Workstation. An external SCSI device is connected as follows: 1. Assign an unused SCSI address to the accessory. SCSI addresses range from 0 to 15 for wide 16-bit SCSI devices. The SCSI address 0 is reserved for the first SCSI hard disk drive and SCSI address 7 is reserved for the SCSI controller (the default for narrow and wide SCSI devices). Refer to the manual provided with the SCSI accessory for instructions on selecting a SCSI address. You do not need to set a SCSI address for Plug-and-Play SCSI devices (SCSI devices that support the SCAM protocol). Chapter 1 45
