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.
