Hey all, wondering if you could help me.

A few months ago I was out of town and apparently the fans on my switch started going crazy. I told my roommate to unplug it and I would deal with it when I get home.

Now the switch seems to be working fine except I get no activity lights on the 10g SFP+ ports when i plug my fiber transciever in. The other end is connected to my desktop over 100m of OM3 Fiber.

It’s detecting the Transciever for sure, because I see this in the console when I replug it:

Port 1/3/1 optics removed

Port 1/3/1 optics inserted, wait for Phy port initialization…

​

I’m not a network guy and my switch knowledge is very limited. Not sure where to go from here. I only have the one fiber cable, otherwise I would try testing them by plugging into my servers (which are currently connected with a QSFP breakout on the back).

Should I order an LC fiber patch cable to test with or is there something I can test/reset in the console?
