GX440 (ES440) Serial Port Reverse Telnet

The Seirra Wireless Airlink Series has the ability to user the serial port connector as a tenet interface to the console port on network equipment. Here is information on how to set that up for a Cisco device console port.

Build the appropriate cable connection using an existing cisco console cable or making an adapter. 

• Use a Male-to-Male Null Modem adapter to connect the blue cisco console cable to the serial port 
• Build an adapter with a DB9m to RJ45 adapter.
  

Configure the GX440 (ES440) serial port settings.
