Console Port
The console port is connected to the configuration terminal using an RJ-45 
connector. You can use the console port for system debugging, configuration, 
maintenance, management, and loading application files. 
The console port can also be connected to a modem for functions such as remote 
system debugging, configuration, maintenance, and management. You can 
configure the baud rate on the console port. 
Table 8 lists console port specifications.
AUX (Modem) Port
The AUX port uses an RJ-45 connector and serves as a backup port for the console 
port to connect a background terminal or a modem for remote system debugging, 
configuration, maintenance, and management. Table 9 lists AUX port 
specifications. 
Module LEDs 
The module LEDs show the status of the I/O modules, as described in Table 10.
