Hi, two weeks before I installed switch JG540 (model in subject).
This morning , when i arrive at the office, some switch ports were not working, I unplug the switch and plug back and watch that connection lights are switch off , just the power light is on(green intermitent). I wait and repeat the process several times but nothing. Then I try to disconnect giga port that is connected to another switch and then all the lights switch on , next I connect giga port and all ok again, all lights on and all pc's connected to LAN . It is a very rare thing.
Do you think it can be any explanation?. Thank you!
