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
