Appendix A Cabling; Scsi Port Connections; Fibre Channel Connections; Serial Port Connections - ATTO Technology FibreBridge 2370E Installation And Operation Manual

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.
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 communicates 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.

Cabling

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.
Cable length Cable type
Up to 175 multi mode fiber
meters optic
Up to 500 multimode fiber
meters optic
Up to 13 unequalized
meters copper

Serial port connections

The ATTO FibreBridge supports remote service
operations over the RS-232 serial port using
standard terminal emulation software available
with most systems.
Connect a DB-9 crossover serial cable (null
modem) between the ATTO FibreBridge serial
port and one of the computer's serial COM ports.
A gender changer or DB-9 to DB-25 converter
may be needed depending on the cables being
used.

Ethernet connections

The 10/100 BaseT Ethernet port provides remote
monitoring and management using the ATTO
ExpressNAV interface.
When you connect an Ethernet cable between the
FibreBridge and a 10/100Base-T connection, you
may need a crossover cable connecting directly to
a computer. The ATTO FibreBridge auto detects
the Ethernet speed by default.
