alarms related to Optical power control
Span Loss Change
（
Minor
）
：
Span
可以理解为两个站点功率监控点之间的总衰耗。
当
之间的衰耗值变化范围超出允许的门限时（默
认设置为０．５ｄＢ），就会出现此告警。
处理之前需要确认一下告警的产生
是否暂时的。这种情况多出现于调试阶段，经常会关闭和开启某个
OTU
单元的激光器导致站点之
间的衰耗值出现变化。类似的此种情况在恢复后告警自
动消失。如果是由于光缆衰耗割接等引起的一些不可恢复性的衰耗，就需要将
放大器的<
/p>
GAIN
增益调整到新的数值以适应新的链路状态。具体的做法只
需打开
Gain
窗口，
Adopt
然后
Apply
就可以了。
Out of Tracking Limitation
< br>（
Major
）
：放大器的自动
跟踪功率变化有个范围，默认为
0.5~3dB,
一当超出这个范围，就会有告警，同时还会伴随
Span
Loss Change
。由于此时功率变化的范围比较大，必须要认真检查是否线路的
衰
耗或者板卡等有故障。例如光纤插拔之后没有复原到位，或者增加或减少了波道的输入
。如果是由于光缆割接引起的光缆衰耗的增加
和减少，意味着没有办法回到系统初始的状
态，整个时候同样也可以改变放大器的
Gain
来消除告警。<
/p>
Out Of SetCapability
< br>（
Major
）
：放大器的增益
是有限的，同时自动跟踪功率变化也有一个限度。放大器其实是通过调节自身之前的
可调
衰耗值来调节在线路中的增益的。当线路衰耗的变化无法使得放大器调整到合适的增益以满足要求的输出功率的时
候，就会有此
告警。此时需要建议客户能否将线路的衰耗尽量恢复到初始值。如果不行，
只能将放大器的既定输出更改到合适的值。保证放大器能
够在正常范围内工作。
PWR_CTL_OUT_OF_TRACKING_LIMITATION
Required correction is greater than
Tracking Limit and had been suppressed
PWR_CTL_SPAN_LOSS_CHANGE
Required correction is greater than Low
Alarm Threshold and had been added
PWR_CTL_OUT_OF_SET_CAPABILITY
Required correction is beyond the gain
capability of the card. The set correction is less
than the required.
PWR_CTL_OUTPUT_PWR_INCORRECT
Required correction is beyond the gain
capability of the equipment. The set correction is
less than the required.
PWR_CTL_GAIN_BLOCK_INPUT_OVERLOAD
Gain input Overload

when LCAS
is supported indicates that one or more of the
