When the COM port is configured to perform the UPS 
application, all future Local Management connections must be 
made by establishing a Telnet connection to the device. Ensure 
that the device has a valid IP address before saving changes to 
the COM port application. If the device does not have a valid IP 
address and the changes are saved, refer to

instructions on clearing NVRAM in order to reestablish COM 
port communications.

Clearing NVRAM results in the loss of all user-entered 
parameters. Do not proceed unless the following procedure is 
completely understood.
