To access the control console, you can use a local computer (a computer that connects to the Network 
Management Card or other device through the serial port).

1. Select a serial port at the local computer, and disable any service that uses that port.

2. Use the configuration cable to connect the selected port to the serial port (J2) on the controller 

board. The controller board is in the right compartment of the electrical panel.

Electrical Hazard: Potentially dangerous and lethal voltages exist within the 
electrical cabinet. Do not touch components on the electrical panel other than the serial 
port.

3. Run a terminal program (such as HyperTerminal
