What is snmp540LedStatus?
A 2-octet bitwise snapshot of the unit's front-panel LED states, covering signals like No Signal, Send/Receive Data, Carrier, Terminal Ready, and diagnostic-test indicators. An admin polls this to remotely see the same status the front-panel LEDs would show someone standing in front of the unit.
