User or Management Interface
The access unit must first be directly connected to a PC or async (or other

or you can completely configure the unit. Refer to the User's Guide for configuration
information.
1. Connect a PC or async terminal to the access unit's COM port.

3. Edit the Communications Port options.
4. Edit the Node IP Address option if management will be via a Telnet session, through
a LAN adapter, router, or terminal server.
