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 switch module. Ensure that the switch module has a valid IP address before saving
changes to the COM port application. If the switch module does not have a valid IP
address and the changes are saved, refer to your switch module hardware/user’s guide
for instructions on clearing NVRAM 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.
