MS225 switch upgrade - SFP uplink port disconnected

We have a plethora of MS 225 switches and I am upgrading to the 14.3.3.1 firmware.

 

I did a single switch last night and noticed the SFP link to another MS225 (that was not upgraded) was disconnected. I had to cycle the port to reestablish a connection

 

Is this due to different firmware on the switches, and have others noticed this issue.

Kind of a big deal

I have never heard about this issue.Are these switches stacked?

The MS225 not stacked

 

I am aware switches in a stack like the MS350 MS410 need the firmware upgraded at the same time.

UPDATE

 

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

@AxL1971 Are the switches reporting the firmware version you are expecting?
