Just a quick note on this firmware release; I had an S48-APOE on my desk for testing that I applied this firmware update to, and it seemed to cause the fans to really start running hard after it was applied. Rebooting the switch from the controller didn’t affect the fans but power cycling the unit by pulling the power and plugging it back in seems to have calmed it down. The switch seemed to be working properly otherwise.

Might have just been a weird glitch but I wanted to make sure to report it here just in case. No other issues so far!
