5 SEC Yellow Secondary Ethernet: LAN2. Activity
Green Secondary Ethernet: LAN2. Link
6 BEAT Yellow Heartbeat, normally 1 Hz 50% duty cycle
7 STAT Green Remains lit when controller is on

If the BEAT LED stays on constantly, does not light, or blinks very fast, have your ABCS Distributor contact the FSC or your appropriate technical support group.

Important: The 1 Hz, 90/10 percent on/off BEAT flash at startup also occurs during other critical operations, such as a firmware upgrade to the controller or any attached modules. To be safe, do not remove power from the controller while its BEAT LED flashes with a 90/10 percent on/off duty cycle. Wait for the normal 50/50 percent flash to return before you remove power.
