Corrective Action
Check the cable connections between the ZyAIR, the power injector and your computer
or switch. Use a cross-over Ethernet cable to connect the power injector to a computer.
Use a straight through Ethernet cable to connect the power injector to a switch or router.
Ping the ZyAIR. Make sure your computer's Ethernet card is installed and functioning
properly.
In the computer, click Start, (All) Programs, Accessories and then Command
Prompt. In the Command Prompt window, type "ping" followed by the ZyAIR's IP
address (192.168.1.2 is the default) and then press [ENTER]. The ZyAIR should reply.
You must connect to the ZyAIR's current IP address and your computer's IP address
must be in the same subnet as the ZyAIR's IP address.
If you don't know the ZyAIR's IP address, you can check the IP address in the System
Management Terminal (SMT). Use the included console cable to connect the ZyAIR's
console port to a computer running a terminal emulation program set to VT100
terminal emulation, no parity, 8 data bits, 1 stop bit, no flow control and 9600 bps
port speed.
If the ZyAIR is set to get an IP address via DHCP, you can check the DHCP server
to see which IP address it assigned to the ZyAIR.
If you've forgotten the ZyAIR's password, refer to the Resetting the ZyAIR section in the
User's Guide.
Make sure the ZyAIR is connected to the network.
Make sure that your computer's IP address is in the same subnet as the ZyAIR's IP
address. If you are using a wireless client:
• Make sure the wireless adapter is working properly.
• Check that both the ZyAIR and wireless client(s) are using the same SSID, channel
and WEP keys (if WEP encryption is activated).
