The ATTO FibreBridge 2300E is a 2-Gigabit Fibre Channel to SCSI bridge which can be embedded in
a variety of enclosures for midrange high performance, cost effective solutions in enterprise
environments.
The the 2-Gigabit FibreBridge 2300E includes
one Fibre Channel port and two SCSI ports and
conforms to the width of the standard 3.5-inch
drive form factor. ATTO Technology FibreBridge
software executes from the Intel 80303, an
integrated I960JT processor and PCI-PCI bridge.
• 128 MB SDRAM, capable of 800 MB/sec.
• Qlogic ISP2300 Fibre Channel controller with a
copper or optical SFP module interface.
• LSI 53C1010 SCSI controller provides interface
with two Ultra 3 SCSI buses.
• Ethernet interface is a 10/100Base T
implemented with an Intel 82559ER Ethernet
controller accessible from the RJ45 connector.
Board dimensions
Width: 3.9 inches wide (9.91 cm)
Length: 7.995 inches long (20.31 cm)
Cooling and airflow
Operating Temperature: 5-40° C

Power
The drive power connector (18 watts) allows the
FibreBridge 2300E to draw power from a
standard 12/5V drive.
Fibre Channel port
The single 2-Gigabit Fibre Channel port can
connect the FibreBridge to either a Fabric or
Arbitrated Loop.

SCSI ports
The two SCSI ports on the FibreBridge 2300
connect storage devices into the Fibre Channel
Storage Area Network (SAN). Each port is totally
independent from the other.
The ports are Ultra 3 LVD/SE SCSI busses with
68-pin "P" interface: 160 MB/sec. max
throughput, downward compatible with all forms
of single-ended SCSI.
Ethernet port
The 10/100 Base T Ethernet port assessable from
the RJ45 connector supports SNMP- and Telnet-
based monitoring and management through a
command line interface, menu system or ATTO
ExpressNAV.
Serial interface
The 10-pin serial connector provides remote
monitoring and management through a command
line interface or the menu system
