Maintenance
Using the RS-232 Management Port
Use the RS-232 management port only when you must manually change the IP address and
subnet mask. Also, use the port if you do not remember the administrative IP address you
entered on your modem.
The Megabit Modem 400F and 500L do not have an RS-232 port.
