50c *ambient* though (and even here in Sydney we've hit 46c), in outdoor enclosures you can easily end up being 20c+ higher, even with ventilation. A bunch of friends of mine have worked for service providers here that used to run networking kit in such enclosures. _______________________________________________ time-nuts mailing list -- [email protected] -- To unsubscribe send an email to [email protected] To unsubscribe, go to and follow the instructions there.
