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 2M46-04R was previously assigned a valid IP address, reenter Local Management by establishing a Telnet connection to the device. If the device does not have a valid IP address and the COM port has been disabled or the settings changed, reset NVRAM on the

2M46-04R (refer to Appendix C) to reestablish COM port communications.

2.Press the SPACE bar to choose either ENABLED or DISABLED. ENABLED allows the COM port to be connected to the terminal and used for a particular application. DISABLED disables the COM port connection to the terminal.

!	If the COM port is configured without a valid IP address, the
	screen shown in Figure 5-11displays.
CAUTION	Do not continue unless the outcome of the action is fully
	understood. If the Warning screen displays, continue on to
	step 3, otherwise, proceed to step 4.
