CAUTION

Do NOT disable or alter the settings of the COM port while operating the current Local Management connection through a terminal. Altering the COM port settings disconnects the Local Management terminal from the port, and ends the Local Management session. If the module was previously assigned a valid IP address, reenter Local Management by establishing a Telnet connection to the module. If the module does not have a valid IP address and the COM port has been disabled or the settings changed, reset NVRAM on the module (refer to Section B.2) to reestablish COM port communications.

2.Press the SPACE bar to choose either ENABLED or DISABLED. The COM port must be ENABLED if it will be used for Local Management or UPS applications. Select DISABLED if you wish to disable the COM port for additional module security.

If the COM port is reconfigured without a valid IP address set

	fully understood.
