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 module.
Ensure that the module has a valid IP address before saving
changes to the COM port application. If the module 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.
