29 Chapter 1 Getting to Know Your ZyAIR
1.2.1.4 ZyAIR LED
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.
1.2.1.5 Bridge/Repeater LED
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.
1.2.1.6 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. 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.

1.2.2 Firmware Features
1.2.2.1 Dual WLAN Interface
The ZyAIR can operate with two WLAN cards. One of the cards is built-in. Another card can
be added using the extension slot on the side panel of the ZyAIR.
With two WLAN cards, the ZyAIR can be set up with two different wireless configurations,
for example, an
Access Point with one card and an AP+Bridge with the other card.
