h3c s5110-28p-pwr交换机光模块插到25号口,光纤也插上了,只是灯不亮,查看状态,显示如下:
请问该怎么办

最佳答案
您好,请知:
1、请确系光模块是否被设备读取以及光衰的情况,可参考如下命令:
[H3C]display transceiver manuinfo interface //查看光模块生产厂家信息
[H3C]dis transceiver interface GigabitEthernet 1/0/1 //查看光模块的信息
[H3C]dis transceiver diagnosis interface GigabitEthernet 1/0/1 //查看光口的收发情况
[H3C]dis transceiver alarm interface GigabitEthernet 1/0/1 //查看光口的告警信息
2、尝试更换光纤及光纤收发试一下。
3、尝试强制设置光口的速率及双工模式
4、尝试关闭接口的STP
5、确认设备的具体距离有多远,看光模块的距离是否可达。

对端也是S5110-28P-PWR ,接的25号接口,插的光模块
对端也是S5110-28P-PWR ,接的25号接口,插的光模块
光模块是1310的还是850的?两端光模块是否一致?单纤还是双纤?传输距离有多远?
