Introducing the PSFR-CP41Operating as Both a SCSI and Fibre Channel De
Operating as Both a SCSI and Fibre Channel
Device
The router is both a SCSI and Fibre Channel device operating on a SCSI bus
and Fibre Channel network simultaneously.

The SCSI Side

On the SCSI bus, the PSFR-CP41 acts as a SCSI initiator passing requests
from hosts on the Fibre Channel network to target devices on the SCSI bus. The
PSFR-CP41 uses a single SCSI ID. The default ID is 7 and can be changed
when configuring the PSFR-CP41.

The Fibre Channel Side

In a Fibre Channel loop, the PSFR-CP41 is identified by a single Arbitrated Loop
Physical Address (AL_PA) or a fabric assigned Source ID. Once the address is
acquired, any host on the Fibre Channel loop can access the devices on the
SCSI bus transparently over a FC connection.

Mapping Devices

To allow Fibre Channel and SCSI devices to address each other, the PSFR-
CP41 creates a table that maps device identifiers between Fibre Channel and
SCSI. During PSFR-CP41 configuration, you can choose the mapping method
and, in certain cases, customize the device mappings. See Chapter "Under-
standing the PSFR-CP41 Configuration" for more information about address
modes and their configurations.
