CAUTION
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
Appendix C for
instructions on clearing NVRAM in order to reestablish COM
port communications.

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