Chapter 1 Getting to Know Your ZyAIR

The blue ZyAIR LED (also known as the Breathing LED) is on when the ZyAIR is on and 
blinks (or breaths) when data is being transmitted to/from its wireless stations. You may use 
the web configurator to turn this LED off even when the ZyAIR is on and data is being 
transmitted/received.

A Bridge/Repeater link LED turns steady on green when your ZyAIR acts as a bridge, 
establishing up to six wireless links with other APs. 

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. An injector or PoE device (not 
included) is also needed to supply the Ethernet cable with power. This feature allows increased 
flexibility in the locating of your ZyAIR. You only need to connect the external power adaptor 
if you are not using PoE. If you simultaneously use both PoE and the external power adaptor, 
the ZyAIR will draw power from the PoE connection only. Refer to the appendix for more 
information about PoE.

Wi-Fi Protected Access (WPA)  is a subset of the IEEE 802.11i security specification draft. 
Key differences between WPA and WEP are user authentication and improved data 
encryption.

Layer-2 isolation is used to prevent wireless clients associated with your ZyAIR from 
communicating with other wireless clients, AP’s, computers or routers in a network.
