Syntax Conventions
• The NXC-8160 wireless switch may be referred to as the “NXC-8160”, the “WLAN
controller” or the “system” in this User’s Guide.
• Product labels, screen names, field labels and field choices are all in bold font.
• A key stroke is denoted by square brackets and uppercase text, for example, [ENTER]
means the “enter” or “return” key on your keyboard.
• “Enter” means for you to type one or more characters and then press the [ENTER] key.

Maintenance > Log > Log Setting means you first click Maintenance in the navigation
panel, then the Log sub menu and finally the Log Setting tab to get to that screen.
• Units of measurement may denote the “metric” value or the “scientific” value. For
example, “k” for kilo may denote “1000” or “1024”, “M” for mega may denote “1000000”
or “1048576” and so on.
• “e.g.,” is a shorthand for “for instance”, and “i.e.,” means “that is” or “in other words”.

Introduction
Getting to Know Your NXC-8160 (23)
Introducing the Web Configurator (27)
21
22
CHAPTER 1
Getting to Know Your NXC-8160
This chapter introduces the main features and applications of the NXC-8160.
1.1 NXC-8160 Overview
The NXC-8160 is a WLAN controller that allows you to connect the NWA-8500 access points
(APs) to extend your wireless network. The NXC-8160 centralizes the management of all of
the connected APs. You can maintain the APs through the NXC-8160; thus eliminating the
need to connect to and configure each AP individually. The AP acts as an antenna of the NXC-
8160.
If you have more than one NXC-8160 in your network, you can manage the other NXC8160(s) through a NXC-8160. You can also set one NXC-8160 as the main WLAN controller,
and the other as the backup when the primary is not active or cannot work properly.
The NXC-8160 provides secure wireless connectivity to your wired network. The NWA-8500
supports two radios (wireless transmissions of signals) simultaneously which can be of the
same or different IEEE 802.11 mode. That means both IEEE 802.11b/g and IEEE 802.11a
compatible clients can wirelessly access the wired network behind the NXC-8160 through a
connected access point.
" Only use firmware for your NXC-8160’s specific model.
See Chapter 11 on page 81 for a complete list of features.
1.2 Application for the NXC-8160
Here are some examples of what you can do with your NXC-8160.
1.2.1 Wireless Internet Access
You can connect a cable or DSL modem/router to the NXC-8160 for broadband Internet
access via an Ethernet port on the modem/router. Both IEEE 802.11a or IEEE 802.11 b/g
wirless clients can access the network behind the NXC-8160 through the access point(s)
connected to the NXC-8160.
NXC-8160 User’s Guide

Chapter 1 Getting to Know Your NXC-8160
Figure 1 Wireless Internet Access
1.2.2 Backup NXC-8160
To ensure wireless Internet access availability, deploy one NXC-8160 as the main WLAN
controller and the other NXC-8160 as the backup. Both NXC-8160s should be in the same
network and have the same number of connected access points and use the same wireless
settings (such as SSID, channel, IEEE 802.11 mode and security). If the main NXC-8160 fails,
wireless clients can still access the Internet or wired network by connecting to the backup
NXC-8160.

Chapter 1 Getting to Know Your NXC-8160
1.3 Ways to Manage the NXC-8160
Use any of the following methods to manage the NXC-8160.
• Web Configurator. This is recommended for everyday management of the NXC-8160
using a (supported) web browser.
• Command Line Interface. Line commands are mostly used for troubleshooting by service
engineers.
• SNMP. The device can be monitored by an SNMP manager. See the SNMP chapter in this
User’s Guide.
1.4 Good Habits for Managing the NXC-8160
Do the following things regularly to make the NXC-8160 more secure and to manage the
NXC-8160 more effectively.
• Change the password. Use a password that’s not easy to guess and that consists of
different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
" If you forgot the password, you cannot restore the defaults and need to contact
your vendor or customer support.
• Back up the configuration (and make sure you know how to restore it). Restoring an
earlier working configuration may be useful if the device becomes unstable or even
crashes. If you backed up an earlier configuration file, you would not have to totally reconfigure the NXC-8160. You could simply restore your last configuration.

CHAPTER 2
Introducing the Web
Configurator
This chapter describes how to access the NXC-8160 web configurator and provides an
overview of its screens.
2.1 Web Configurator Overview
The web configurator is an HTML-based management interface that allows easy NXC-8160
setup and management via Internet browser. Use Internet Explorer 6.0 and later or Netscape
