Module: MOXA-NP6000-MIB

OID (symbolic): MOXA-NP6000-MIB::alarmDSRchange

Description: A change in the DSR (Data Set Ready) signal indicates that the data communication equipment is powered off. For example, if the DSR signal changes to low, it indicates that the data communication equipment is powered down. When the DSR signal changes to low, the NPort 6000 series device server will immediately raise a d-out alarm.

What is alarmDSRchange?

When enabled, the NPort raises a digital-output alarm whenever the serial DSR signal changes state, e.g. going low to indicate attached equipment lost power; the hardware-alarm counterpart to mailDSRchange/trapDSRchange.
