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.
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.

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.

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.
