Interpreting the Indicator LEDs
Note Mini PCI cards do not have LEDs.
The client adapter shows messages and error conditions through its two LEDs:
• Link Integrity/Power LED (green)—This LED lights 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 indicate an error condition.
Table 10-1 interprets the LED messages during normal operation. Table 10-2 interprets the LED error
condition messages.
