1-2 Getting to Know Your ZyAIR
ZyAIR LED
The blue ZyAIR LED (also known as the Breathing LED) is on (dimmed) when the ZyAIR is on and blinks
brightly 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.
802.11g Wireless LAN Standard
ZyAIR products containing the letter “G” in the model name, such as ZyAIR G-1000, ZyAIR G-2000,
support the 802.11g wireless standard.
802.11g will be fully compatible with the 802.11b standard. This means an 802.11b radio card can interface
directly with an 802.11g access point (and vice versa) at 11 Mbps or lower depending on range. 802.11g has
several intermediate rate steps between the maximum and minimum data rates. The 802.11g data rate and
modulation are as follows:
802.11g
Data Rate (Mbps) Data Rate (Mbps)
1 ~ 54 1 ~ 54
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.
Wireless LAN MAC Address Filtering
Your ZyAIR checks the MAC address of the wireless station against a list of allowed or denied MAC
addresses.
IEEE 802.1x Network Security
The ZyAIR supports the IEEE 802.1x standard to enhance user authentication. Use the built-in user profile
database to authenticate up to 32 users using MD5 encryption. Use an EAP-compatible RADIUS (RFC2138,
2139 - Remote Authentication Dial In User Service) server to authenticate a limitless number of users using
EAP (Extensible Authentication Protocol). EAP is an authentication protocol that supports multiple types of
authentication.
Brute-Force Password Guessing Protection
The ZyAIR has a special protection mechanism to discourage brute-force password guessing attacks on the
ZyAIR’s management interfaces. You can specify a wait-time that must expire before entering a fourth
password after three incorrect passwords have been entered. Please see the appendix for details about this
feature.
