255.255.255.0. You don’t need to do anything 
more if you want to use the default, but these 
parameters can be changed using the RS-232 port 
or Telnet. The ATTO FibreBridge should first be 
configured for the network using the RS-232 port 
to establish the correct IP address. 
To set up the IP Address using the RS-232 port 
and the menu system: 
1 Connect a DB-9 serial cable to the ATTO 
FibreBridge serial port and establish a link.
2 Enter the menu system by typing MENU at 
the prompt
3 At the Main Menu, select FibreBridge 
Configuration
4 At the FibreBridge Configuration Menu, 
select Network Configuration
5 At the Network Configuration Menu, select 
IP Address
6 Enter the desired IP Address
To set the IP Subnet Mask: 
1 At the Main Menu, select FibreBridge 
Configuration

Access the ATTO FibreBridge using Telnet or FTP over Ethernet
To access the ATTO FibreBridge via Ethernet:
1 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 will auto detect the Ethernet 
speed if configured to do so.
2 Access using any standard Telnet program. 
To connect via Telnet:
1 Supply the IP address to the Telnet program. 
The local echo should be set to on if the 
Telnet software supports it. Use Vt100 for 
communication. 
2 Verify that the bridge can be accessed on 
the local Ethernet by using the Ping utility. 
On most systems, type ping <IP Address>. If 
the FibreBridge does not respond, it may 
not be connected correctly to the network, 
or is somehow unreachable by the 
computer from which it is being pinged. 
Check network connections and security as 
well as the ATTO FibreBridge.
To set up and configure FTP:
1 Ensure that the FTP program is in binary 
mode. Access the ATTO FibreBridge at the 
IP address that was previously set (or the 
default).
2 Log into the ATTO FibreBridge. The 
username the bridge will accept is sysadmin. 
Enter userid as the password.
