Getting to Know Your ZyAIR
1-3
Bridge/Repeater
A Bridge/Repeater link LED turns steady on green when your ZyAIR acts as a bridge, establishing a wireless
link to another AP. It turns steady on orange when your ZyAIR acts as a repeater, establishing wireless links
to two or more APs.
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.
