电源适配器2

电源适配器不匹配会带来哪些宽带问题?
What broadband problems will the power adapter mismatch bring?
故障现象:
Failure phenomenon:
在光纤入户中,出现了直播电视可以正常收看,但是宽带和互动节目不能正常使用。
In the optical fiber into the home, there is live TV can be normal watching, but broadband and interactive programs can not be used normally.
处理过程:
Process:
高清机顶盒、ONU和路由器面板上的电源指示灯均正常亮起。观察到ONU光纤E信号灯不正常(无信号该灯为红灯),光纤C信号灯正常。使用光功率计测试宽带信号,信号指标正常。
The power indicators on the HD set top box, ONU and router panel are all on the normal side. It is observed that the ONU fiber E signal lamp is abnormal (no signal is red light) and the C signal lamp is normal. Using optical power meter to test broadband signal, the signal index is normal.
查看所有设备的电源发现ONU电源适配器和金钱猫路由器电源适配器对换接了。由于瑞斯康达标称电压和电流是12V,1A,金钱猫路由器电源适配的标称电压和电流施9V,0.6A,由于电压不够导致ONU不能正常工作的原因(onu的面板指示灯会亮起,也可正常解调出来射频信号,但无法解调出宽带的信号)。将两个电源适配器对换过来互动和宽带可以正常使用了。
View the power of all devices found ONU power adapter and money cat router adapter. Because the voltage and current of the RRC is 12V, 1A, the nominal voltage and current of the power of the money cat routers apply 9V, 0.6A, because the voltage is not enough to cause the ONU to work properly (the ONU's panel indicator lights up, and the RF signal can be demodulated normally, but the broadband signal can not be demodulated). The two power adapters can be switched to interact and broadband can be used normally.
