It monitors two independent -48V power supplies of the subrack and detects overvoltage (-72V) and Undervoltage (-38.4V).
|
|
It provides the centralized backup function of + 3.3V power supply for each board of the subrack (secondary power supply of each board: 1: N protection), and the backup 3.3V power is 80W.
|
|
Overvoltage (3.8V) and undervoltage (3.1V) detection for 3.3V backup voltage.
|
|
Audible alarm
|
Support audible alarm and alarm removal function.
|
|
Network port connection status detection
|
R2AUX supports network port connection status detection.
|
|
Note: The COM port is for internal debugging only and cannot be used for normal device monitoring. Otherwise, the Ethernet communication between boards may be abnormal.
