2. Getting Started
This chapter explains how to access the WAC-2004A for the first time. There are three ways to access the
controller: (1) Web Console, (2) Telnet Console, or (3) Serial Console. The Web and Telnet Consoles are
suitable for remote management as the controller can be accessed over an existing network. The Serial
Console can be used if you do not have the WAC-2004A’s IP address; however it requires using a RS-232
serial cable to connect WAC-2004A to your PC’s COM port.
In addition, the Web Console provides a more complete collection of functions for status monitoring and
controller administration; where the Telnet and Serial Consoles only provide basic administration functions.
The following topics are covered in this chapter:
