1-4 Getting to Know Your ZyAIR
The ZyAIR may be prone to RF (Radio Frequency) interference from other 2.4 GHz
devices such as microwave ovens, wireless phones, Bluetooth enabled devices,
and other wireless LANs.
Antennas
The ZyAIR is equipped with two reverse SMA connectors and two detachable omni-directional 2dBi
antennas to provide a clear radio signal between the wireless stations and the access points. Refer to the
Antennas appendix for more information.
The following table shows the ZyAIR’s coverage (in meters) using the included antennas. The distance
may differ depending on the network environment.

4-Port Switch
A combination of switch and Internet gateway makes your ZyAIR a cost-effective and viable network
solution. You can connect up to four computers to the LAN ports on the ZyAIR without the cost of a hub.
To connect more than four Ethernet devices, attach a hub or switch.
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.
Reset Button
Use the reset button to restore the ZyAIR back to its factory defaults.

subscriber accounts on the ZyAIR and print out the account information on-site without using a computer.
The statement printer is also known as an “account generator” or “exclusive printer”.
