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. 

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.  

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.
