Upgraded 30 MS 225 switches last night and 2 of the switches had the issue. I power cycled the port and this not resolved the issue. Both switches were upgraded at the same time so running the same firmware.
Now, came back this morning and did the same power cycled the ports and now connected.
This is the connection status of the 2 switches port 49
As you can see the timeframe when the links were not connected
