ATTO Technology Inc. FibreBridge Installation and Operation Manual
1.1 Cabling
ATTO FibreBridge SCSI ports connect SCSI storage devices into the Fibre Channel Storage Area
Network (SAN). Use an Ethernet connection to use the ATTO ExpressNAV interface (not available for
the FibreBridge 1180).
Make sure all cables are anchored securely at both
ends with the proper connectors.
SCSI port connections
The FibreBridge supports a wide variety of SCSI
storage devices including stand-alone drives,
removable drives, JBODs, tape, CD and DVD
drives, changers, libraries and magneto optical
drives.
Each SCSI port is totally independent from the
other SCSI port. Each bus may support up to 15
devices and each SCSI bus auto-negotiates the
appropriate sync rates with the connected devices.
If slower devices are mixed with faster devices,
the bus will communicate at the rate of the slowest
device.
Connect slower devices to one SCSI port and
faster devices to the other port.
Connect a SCSI connector from the SCSI device
to a SCSI port on the FibreBridge.
Check the type of cable, cable length limit and
number of devices recommended for each port.
Keep cable lengths as short as possible to ensure
the highest signal quality and performance. These
cable lengths include the wiring inside the
devices.
Fibre Channel connections
Fibre Channel technology offers a variety of
cabling options. The type of cable required varies
depending upon the application, environment and
distance.
The type of connector depends on the FibreBridge
model.
