SCSI Connection 4-15
SCSI Connection
The FCR200 supports Fast/Ultra Wide SCSI. The FCR200 is
factory configured to support either a Single-Ended or
Differential SCSI bus. Four 68-pin D-shell connectors are
located on the rear panel of the unit, allowing the unit to be
attached in the middle or at the end of a SCSI bus. If the
FCR200 is located at one end of the SCSI bus, an external
terminator should be installed. Two terminators are provided
with the FCR200.
The FCR200 supplies termination power (TERMPWR) on each
SCSI bus. A self-resetting fuse is used that will reset after the
fault is cleared.
To connect the FCR200 to a SCSI bus:
1 Power off your SCSI devices.
2 Connect a SCSI cable to one of the SCSI connectors
on the back of the router. If necessary, use a narrow-
to-wide adapter.
3 Connect the other end of the SCSI cable to the next
SCSI device on the bus.
4 If the FCR200 is at the end of the SCSI bus, place the
terminator provided with the router on the
FCR200’s other SCSI connector on the same bus. If
the router is not at the end of the bus, attach a
second SCSI cable to the other SCSI connector. Use
a narrow-to-wide adapter, if necessary. Connect
this cable to the next device on the bus.
Single-Ended SCSI support is indicated by
this symbol on the rear of the FCR200.
Differential SCSI support is indicated by
this symbol on the rear of the FCR200.
