Ethernet Operations, Administration, and Maintenance (OAM) is a guarantee to provide
high-quality carrier-class network. It monitors link status change, makes evaluation of
service quality provided by the link, so as to provide great convenience for network
maintenance staff to locate network failures. ZXR10 5250 supports three OAM protocols:

2.11 Off-power alarm
When the power supply is off-power, the device sends alarm message to the designated
server, notifying the server that the device stops working because the power supply is off.
Power supply failure is the major failure of the access device. This function can help OAM
staff to make quick decision on device failure and speed up the processing and failure
recovery.
