AN-X2-GENI (AN-X-GENI/B)
May 2013
Troubleshooting
LEDs
The AN-X2-GENI has LEDs that indicate the state of the Ethernet connection, the
overall module state and the connection to the Genius I/O network.
Ethernet LEDs
There are two LEDs that indicate the state of the Ethernet connection.
The upper, yellow LED, labelled 100, is on if the link is running at 100 Mbits/second and
is off otherwise.
The lower green Link/Act LED is off if the link is inactive and is on if the link is active.
If activity is detected, the link blinks at 30 ms intervals and continues blinking as long as
activity is present.
If the AN-X2 is not connected to Ethernet, the 10/100 LED is on.
MS and NS LEDs: Startup
The SYS or MS LED is used by the AN-X operating system and software to indicate the
state of operations and errors. Errors or status indication in boot mode cause the LED to
flash yellow. Otherwise, the LED flashes red.
The SYS or MS LED should be used in conjunction with the logs to locate the cause of
problems.
In the following, red 3 means three red flashes followed by a pause, and so on.
