Serial port LEDs
•
Printer port LED
•
WAN port LED
During the self-test, the LED for each port will cycle through:
1. off
2. green
3. orange
4. off
When the self-test completes, the LEDs will be either off or green. Off indicates a port
that is not in use. Green indicates a port that is in use. The green LED will blink when
data is transmitted or received. It will blink 5 times per second when data is
continuously transmitted or received.
If any of the LEDs turn orange, an error condition was detected. A serial port LED will turn
orange for one blink, then return to green, if a parity, framing, or overrun error is
encountered. Also, a blinking orange or blinking green indicator on the status LED signals
an error. For a description of the error codes, see LED Displays, page 31.
