We have a variety of these switches deployed as well as the 50 port model. After upgrading to version 1.0.0.19 the thermal thresholds had a massive jump from 50 Celcius range to the 90 Celcius range. This is obviously something that couldn't go unnoticed as I upgraded these units. There is a bug report opened (CSCva66629) with Cisco and wanted to know if someone else has seen this change.
