The Front Panel

Dual-Band Wireless A + G Access Point

The Front Panel

The Access Point's LEDs, where information about network activity is displayed, are located on the front panel.

Power

Green. The 

Power

 LED lights up when the Access Point is powered on.

Wireless-A WLAN 

Green. When the 

WLAN

 LED is blinking, the Wireless-A network is operating.

Wireless-G WLAN 

Green. When the 

WLAN

 LED is blinking, the Wireless-G network is operating.
