" Railroading" – SYS and NET LEDs
AN-X2 alternates (railroads) flashing the SYS and NET LEDs to indicate its state.
It railroads the LEDs yellow while it is copying new maintenance or production firmware
files from the microSD card to flash memory.
It railroads the LEDs green for 20 to 30 seconds as it starts production mode.
NET LED – Network Status
The NET LED shows the status of remote I/O communication.
Color

Flashing Red/Off

Startup LED Sequence

At startup, the LED sequence is:
•

Fatal Errors

AN-X2 monitors its operation for " impossible" conditions and generates a fatal error if it
detects one. It generates a fatal error code on the SYS LED by flashing 8 bits followed by
a pause. The least significant bit is first, with green for 1 and red for 0.
If a fatal error occurs, record the SYS LED sequence and contact technical support.
Meaning
A frame receive error has been received in the last second (CRC
error, abort, or timeout), stays red for 1 second after the error
occurs
One or more racks is in error
At least one rack which is being scanned is in error
All racks are being scanned with no errors
fast yellow flash as maintenance boot code performs memory tests, other
startup diagnostics.
fast yellow flash as maintenance firmware runs
railroad yellow if firmware files are being updated
yellow error code if an error occurred in configuration
railroad green as production firmware starts
SYS and NET LEDs green if everything is running and the AN-X2 is active
on the network
