Preface
Congratulations on your purchase of the ZyAIR G-5100 Outdoor 802.11g Business Access
Point/Bridge/Repeater.
The ZyAIR is an Access Point (AP) through which wireless stations can communicate and/or
access a wired network. The ZyAIR can also function as a wireless network bridge/repeater
and establish wireless links with other APs.
The ZyAIR also supports both AP and bridge connections at the same time.
Your ZyAIR is easy to install and configure.
Note: Register your product online to receive e-mail notices of firmware upgrades and
information at www.zyxel.com
American products.
About This User's Guide
for global products, or at www.us.zyxel.com for North
This User’s Guide is designed to guide you through the configuration of your ZyAIR using the
web configurator or the System Management Terminal (SMT). The web configurator parts of
this guide contain background information on features configurable by web configurator. The
SMT parts of this guide contain background information solely on features not configurable
by web configurator
Note: Use the web configurator, System Management Terminal (SMT) or command
interpreter interface to configure your ZyAIR. Not all features can be configured
through all interfaces.

Getting to Know Your ZyAIR
This chapter introduces the main features and applications of the ZyAIR.
1.1 Introducing the ZyAIR
The ZyAIR G-5100 is an enterprise level, outdoor IEEE 802.11g compliant business access
point, bridge and repeater with excellent wireless performance. Wireless Distribution System
(WDS) support provides flexibility in building an extended wireless network with bridge and
repeater applications. IEEE 802.1x, Wi-Fi Protected Access, WEP data encryption and MAC
address filtering offer highly secured wireless connectivity.
Rugged die-cast, watertight construction, built-in lightening protection, and grounding make
the ZyAIR perfect for outdoors applications.
ZyAIR G-5100 User’s Guide
CHAPTER 1
It is easy to install and configure the ZyAIR. The web-based configurator allows remote
configuration and management of your ZyAIR. The Power over Ethernet (PoE) feature means
that power can be delivered to the ZyAIR over an Ethernet line. This allows you to mount the
ZyAIR in areas where there are no nearby power sources.
1.2 ZyAIR Features
The following sections describe the features of the ZyAIR
10/100M Auto-negotiating Ethernet/Fast Ethernet Interface
This auto-negotiating feature allows the ZyAIR to detect the speed of incoming transmissions
and adjust appropriately without manual intervention. It allows data transfer of either 10 Mbps
or 100 Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.
Power over Ethernet (PoE)
Power over Ethernet (PoE) is the ability to provide power to your ZyAIR via an 8-pin CAT 5
Ethernet cable, eliminating the need for a nearby power source. The ZyAIR G-5100 includes a
special high current power injector that allows the ZyAIR to be located farther away. This
feature allows increased flexibility in the locating of your ZyAIR.

Figure 1 PoE Installation Example
Wi-Fi Protected Access
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. Key differences
between WPA and WEP are user authentication and improved data encryption.
WDS Functionality
A Distribution System (DS) is a wired connection between two or more APs, while a Wireless
Distribution System (WDS) is a wireless connection. Your ZyAIR supports WDS, providing a
cost-effective solution for wireless network expansion. The ZyAIR supports up to five
wireless links with other APs.
