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 SmartSwitch device. Ensure that the SmartSwitch device has a valid IP address
before saving changes to the COM port application. If the SmartSwitch device does not
have a valid IP address and the changes are saved, refer to your SmartSwitch device
installation 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.
