FibreBridge 4500
Serial port
The 10-pin serial port connector provides support for 
remote monitoring and management through a 
command line interface, menu system or graphical 
interface (ATTO BridgeTools).
In order to use the RS-232 port, you must ensure there 
is enough clearance above the face plate for the ribbon 
cable: do not place another card in the adjacent slot of 
the CPCI rack. Connect the 10 pin to DB9 converter 
cable to header P3 (in the same corner of the board as 
the RJ45 connector)
LED indicators
Fault
FC 0 Activity, FC 1 Activity, FC 2 Activity: 
each 
LED blinks to show activity on the Fibre Channel port 
(numbered 0, 1 and 2). During very high activity, the 
LEDs appear to be steadily lit.
SCSI 0 Activity, SCSI 1 Activity, SCSI 2 Activity, 
SCSI 3 Activity: 
each SCSI bus has its own LED to 
show activity on that bus (numbered 0, 1, 2, 3). 
Ready: 
should light after the FibreBridge has passed 
its internal self diagnostic test, indicating the 
FibreBridge is ready to operate. Fault: indicates if 
there is a problem with the FibreBridge. If the fault 
LED blinks in a consistent pattern, contact ATTO 
Technology Technical Support.
Installing the FibreBridge 4500C
The ATTO FibreBridge 4500C offers a variety 
of ways to connect into a SAN. 
1 Mount the FibreBridge 4500C into a 
standard CPCI rack mount system or, for 
custom placement, use the mounting holes. 
2 Connect the SCSI devices to the 
FibreBridge. (See Chapter 2.3)
3 Connect the FibreBridge to your SAN: 
attach short wave optical cables into the 
Fibre Channel ports on the FibreBridge. 
(See Chapter 2.4)
4 Connect to the management (services) port 
via the RS-232 serial port, Ethernet, or in-
band SCSI over Fibre Channel. (See 
Chapter 4)
5 Use ATTO BridgeTools™, a graphical 
interface utility enclosed with your 
FibreBridge, or Command Line Interface to 
map your devices to the appropriate 
FibreBridge Fibre Channel ports (See 
Chapter 3.1 and Chapter 4.1.8) 
6 Boot the computers on the SAN and set up 
the configuration for the devices connected 
to the FibreBridge.
