SCSI-Fibre Channel Router Installation and User Guide

1. Introduction
The SCSI-Fibre Channel Router (SCSI-FC Router) is a simple to maintain stand-alone SCSI extender.
By converting SCSI to Fibre Channel, it can provide lengths of 30m (98 ft) to 10 km (6.2 miles)
depending on the fiber optic cable used.
Figure 1-1. SCSI-FC Router
To the host, the SCSI-FC Router is transparent and the device on the Fibre Channel loop appears as a SCSI
device. Since the SCSI-FC Router appears to the host as a parallel SCSI device, its usage and installation are
very simple. The SCSI-FC Router attaches directly to the SCSI host adapter. The SCSI-FC Router is supplied
in a self-contained 3"(H) x 4.25"(W) x 11"(D) enclosure that can either be installed on a desktop or four-
abreast in the 19" rackmountable Hub Enclosure. For more information concerning the SCSI-FC Router Hub
Enclosure, refer to the
Hub Enclosure Installation Guide.

1.2. SCSI-FC
Router
Defined
There are two SCSI-FC Routers in a single Fibre Channel loop. To prevent confusion, the following
diagram defines the various SCSI-FC Routers by their positions within the loop. The SCSI-FC
Router directly attached to the host or the server is the ’host router’ and the SCSI-FC Router directly
connected to the SCSI devices (disk or tape drives) is the ’device router’.
