Cisco Systems 2140 Manual De Usuario

The configuration/setup utility program is located in the Cisco ADE 2130 and 2140 Series appliance 
ROM and can be accessed through the serial (console) port.

The Cisco ADE 2130 and 2140 Series appliance has an RJ-45 serial port connector located on the back 
of the appliance. This connector is shared with the RJ-45 serial port connector located on the front panel.

When one RJ-45 serial port connector is in use, the other is disabled. For example, if the rear-panel RJ-45 
serial port connector is in use, the front-panel RJ-45 serial port connector is disabled and vice versa.

 shows the pin number assignments for the RJ-45 serial (console) port connector on the back 

or front of the appliance. These pin number assignments conform to industry standards.

The serial (console) RJ-45 port pinout differs slightly between the front- and rear-panel ports, 
specifically in relation to Pin 6 and Pin 7.

On the front-panel serial (console) port, Pin 6 is used as a serial port selection input. Grounding the 
signal on Pin 6 disables the rear-panel serial (console) port so that the front-panel port is active. This 
feature allows you to plug into and use the front-panel port without regard to whether anything is 
connected to the rear-panel port.
