Wireless Technologies under Top Issues.
Interpreting the Indicator LEDs
The client adapter shows messages and error conditions through its two LEDs:
• Link Integrity/Power LED (green)— This LED is on when the client adapter is receiving power and
blinks slowly when the adapter is linked with the network.
• Link Activity LED (amber)—This LED blinks quickly when the client adapter is receiving or
transmitting data and blinks in a repeating pattern to show an error condition.
Table 5-1 interprets the LED operating messages.
