I have had success with the opposite approach using equipment rated from
-40 C to +85 C (+185 F), no fans, sealed NEMA4 or NEMA12 Hoffman
enclosures, cooling by equipment heat sinks. Ethernet switches and optics
rated -40 C to +85 C
This configuration has worked with the same equipment for at least 6 years
in an environment where summer ambient temperatures reach 120-130 F, and
winter ambient 0 F. Hoffman makes a 72" high NEMA12 enclosure with a
swing-out 19" telco rack.
