hcxOc3FaultStatusLed

Module: COM21-HCXOC3-MIB

OID (symbolic): COM21-HCXOC3-MIB::hcxOc3FaultStatusLed

OID (numeric): 1.3.6.1.4.1.1141.2.91.1.1.9

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: The Oc3 Fault Status LED is a read-only attribute which describes the condition of the Oc3 Fault Status light emitting diode located on the Oc3 board. A value of on(1) indicates that an fault condition has been detected (for which a trap will have been issued) and the LED is illuminated. Will be off if no card present.

What is hcxOc3FaultStatusLed?

This read-only on/off value mirrors the physical OC-3 Fault Status LED, lighting on(1) when a fault has been detected and a corresponding trap issued, and reporting off if no card is present. It gives an administrator a remote view of the OC-3 card's fault indicator matching what a technician would see at the chassis. For example, an operator receiving a fault trap for the optical trunk could confirm it against this LED status before dispatching a technician.
