I have a pair of 7150-C08p switches.
We installed a 1GbE optical gbic in 1/2/1 on each switch and patched them together...
We are not getting any link.
I am trying to determine if this is a:
Switch config issue?
GBIC compatibility issue?
The switches see the gbic installed, but it is down:

Is there anything from a switch config standpoint that I can check? These switches have not had any explicit configs done to them... they are pretty much right out of the box...
I have ordered a couple different GBICs just in case the ones we have are incorrect.
Our fiber environment is single mode with regular LC connectors.
Solved! Go to Solution.
No special considerations here. That port should be fixed 1Gb, so no need for speed settings or anything like that. I would assume this is a media (optic, fiber, etc.) issue, but tough to say without doing process of elimination. If needed, please feel free to open a case (see my signature) and we can try to help,
lol - ok - so I convinced myself that I wasn't going to totally break the fiber cable trying to get the LC connectors out of the clip... I flipped the cables on one side, plugged in to the gbic and got a link light. So... seems that was the issue.
Appreciate everyone's help... and patience with me being such a freshie with fiber 🙂 lol
The first thing I would do -- put switches side by side, and connect by 2m patch. If no link, swap pairs on one end. If still not working, replace both SFP with known working.
Than I would check if it works with 2 different vendor switches (I mean test same cable + SFPs with different switches).
Only if this way I could determine that all components work with different swicthes, I would open support case.
But it is probably as simple as cable problem, try troubleshooting physical level in the beginning... FO cable fault laser tester helps a lot to be sure you have proper cable connections.
Thanks for the reply. The output shows:
ICX7150-C08P Switch>show media validation
Port Supported Vendor Type
1/2/1 No OEM Type : 1G M-LX(SFP)
...so maybe the GBIC is not compatible? Not sure if "supported" as shown above refers to the ability to get support from Ruckus related to this GBIC (not Ruckus branded) or if the GBIC will not function at all...
I have the same output on my switches. If it is not Ruckus branded it says supported as No. the only ruckus branded modules I have are the stacking cables and everything is working with 3rd party sfp modules.
I normally make the flip on the back side of the fiber patch panel. You can also do it on the patch cable as mentioned previously by taking the clip off changing the pairs and putting the clip back on.
