1 Introducing the ZyAIR
The ZyAIR G-3000 is a wireless access point with two WLAN interfaces that are compliant with both
IEEE802.11g and IEEE802.11b standards. It is suitable for wireless connections to the wired network in
small office environments and businesses. The key features of the ZyAIR are the dual WLAN interface,
internal RADIUS server, PoE (Power over Ethernet), wireless security, and WDS (Wireless Distribution
System). See your User’s Guide for more details on all ZyAIR features. To view a product’s

LABEL DESCRIPTION
CONSOLE Only connect this port if you want to configure the ZyAIR using the SMT (System
Management Terminal) via console port; see your User’s Guide for details.
Connect PS/2 end of the console cable to the console port of the ZyAIR and the other
end to a serial port (COM1, COM2 or other COM port) on your computer. Your computer
should have a terminal emulation communications program (such as HyperTerminal) set
to VT100 terminal emulation, no parity, 8 data bits, 1 stop bit, no flow control and 9600
bps port speed.
ETHERNET Use an Ethernet cable to connect a computer (with an Ethernet card) or switch to the
ETHERNET port. The port is auto-negotiating (can connect at 10 or 100Mbps) and auto-
crossover (automatically adjusts to the type of Ethernet cable you use (straight-through
or crossover)).
RESET You only need to use this button if you’ve forgotten the ZyAIR’s password. It returns the
ZyAIR to the factory defaults (password is 1234 and LAN IP address 192.168.1.2). Refer
to the User’s Guide.
POWER
12VDC
Connect the end of the included power adaptor to this power socket. 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.
Use only the included power adaptor.
EXTENSION
CARD SLOT
This slot allows you to add an IEEE802.11g or IEEE802.11b WLAN card adaptor. You
must have a WLAN card inserted before you can configure it.
The ZyAIR also contains a built-in wireless card.
2.2 The LED Display
When the power is connected the PWR, ZyAIR,SYS,WLAN LEDs turn on in that order. The ETHN
LED turns on, if the ETHERNET port is properly connected. See the ZyAIR Front Panel LED Description
table for more information.
