Protection Board

In this user interface, you can set parameters for protection boards. The parameters are laser status, automatic laser shutdown, maximum or minimum attenuation rate and path use status.

Parameters

Field	Value	Description
Optical Interface/Channel	Equipment that supports the master and slave shelf management: NE name-shelf ID(shelf name)-slot number-board name-port number(port name) Equipment that does not support the master and slave shelf management: NE name-slot number-board name-port number(port name)	Displays the optical interface.
Optical Interface Name	For example: RI1/TO1	Displays the default names. Do not modify this field.
Threshold of Input Power Loss (dBm)	Values of parameters vary with different boards and products. For details, click the links in the Description column.	Sets the threshold of the optical power loss. When the input optical power is below this value, the loss of input signals occurs.
Initial Variance Value Between Primary and Secondary Input Power (dB)	-10.0 to 10.0	Sets the initial variance value between primary and secondary input power.
Variance Threshold Between Primary and Secondary Input Power (dB)	3.0 to 8.0	Sets the variance threshold between primary and secondary input power.
