Operation
5.3 Light emitting diodes
There are three Light Emitting Diodes (LED) on the front of the Rosemount 2460 System Hub for status
and error information.
When the system hub is starting up, all LEDs, (Power, Status, and Error) are lit in order to verify that they
work.
In normal operation the Power On and Status LEDs verify that the system hub is up and running.
