If the fault is caused by incorrect configuration or networking environment, change the configuration or networking environment. However, when I plug Single mode fibre in Multimode module both side of switch link come up. Port not UP Taking 10G SFP+/XFP optical module as an example, when the optical port of the optical module can not be UP when interconnecting with other devices, it can be troubleshooted from the following five.

Solution To resolve the issue: Execute the display power command to check whether the power module is in faulty or absent state. For configuration recovery, regularly back up the configuration to a remote server. The following uses the Moduletek QSFP-40G-LR4 module connected to an H3C S6820 switch as an example to introduce how to read information of the connected optical module on an H3C switch. How to use WA4320X optical port and electrical port at the same time WA4320X supports poe power supply, but the outdoor AP often encounters the problem that the installation location is far from the access switch, so it will use the electrical port poe power supply and the optical port to transmit.

To measure the current, select the DC/AC current function with the appropriate range. Finally, connect the multimeter in series with the circuit and observe the current . Current measurements are easy to make, but they are done in a slightly different. There are a number of methods you can use to measure current, but the simplest way to measure direct current (DC) is by using a digital multimeter A gap is made in the circuit and is connected to a digital multimeter (DMM) so that it becomes part of the circuit itself.
