Hardware Features
On the rear-panel serial (console) port, Pin 7 can be configured with a jumper located on the appliance
motherboard. This jumper allows you to set Pin 7 to either Data Set Ready (DSR) or Data Carrier Detect
(DCD) as might be required when using a serial port concentrator. The default jumper configuration
selects the DSR signal, which conforms to the Cisco serial port standard.
