[CALUG] Ethernet switch below freezing

Off hand, the only thing I could really think of that might be a problem
would be condensation forming on the electronics if it were that cold.
Maybe a chance of some soldier joints pulling free from metal
contracting in the cold, but I really doubt that, given any metal isn't
going to contract that much in cold vs room temp.

If you want to help keep it from getting too cold, put the switch in a
not well ventilated box so that it can keep itself warm.  Just make sure
it can be converted to well ventilated for the summer given 40C/104F can
be quickly reached in a garage in the summer (I'd be tempted to include
a fan on the box).
