e
Operating as Both a SCSI and Fibre ChannelDevice
The router is both a SCSI and Fibre Channel deviceoperating 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
fromhosts on the Fibre Channel network to target devices on the SCSI bus. The
PSFR-CP41 uses a singleSCSI ID. The default ID is 7 and can be changed
when configuring the PSFR-CP41.

The Fibre Channel Side

Ina Fibre Channel loop, the PSFR-CP41 is identified bya single Arbitrated Loop
PhysicalAddress (AL_PA) or a fabric assigned Source ID.Once the address is
acquired, anyhost on the Fibre Channel loop can access the devices on the
SCSI bustransparently over a FC connection.

Mapping Devices

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