https://community.extremenetworks.com/t5/extremeswitching-other/high-temperature-environments-up-to-55o/m-p/10474#M1502 I don't know of any Extreme XOS based switches that meet this requirement. Others can certainly correct me. Depending on your specific requirements and exposure that may be a couple EOS based (formerly Enterasys) switches - the D-series and I-series.
