6224F sfp problem
Hello, I am trying to add a 6224f to a stack that was running with 3 other switches. Switch 1 was a 6224F, Switch 2 was a 6248p, Switch 3 was a 6248. I added the new 6224f and set it up as stack member 2. All switches are running the latest firmware and boot code.
For some reason none of the SFP ports on the recently added 6224f are working properly. If I try to connect a device to the switch the port light never comes on. The SFP and the cable are good though. The 4 copper ports on the switch do not exhibit this behavior.
Strangely if I do a loopback and connect a patch cable between two ports on the switch the link light does come on.
So, the cables are good, the sfps are good and the ports are good but they only work when looping back to ports on the same switch.
Any ideas?
Thanks
Hi Daniel,
The connection that I was trying to make is good. I had a bunch of LAGs that were running on one switch that I was trying to split between two of them. They were both functional on the first switch but the port would not come up at all when I tried to move it to the problematic 6224f. I also checked the ports with a Fluke Linkrunner with an SFP module in it.
I checked the logs, they just showed the transceivers being inserted and taken out as I was testing different ports. No errors, just informational stuff. All of the ports seem to recognize when they have a transceiver in them, they just don't send any data.

Hi Daniel,
I removed the switch from the stack, I think is is most likely defective and out of warranty. I formatted and restored the file system, reinstalled the firmware, updated boot code again and it didn't help. The SFPs still only worked when looped on the switch. The issues were the same when it was part of the stack or solo.
