Wide Temp range Switch? Any out there?

[RU482]

I'm working on a project where the customer wants to have a ~24 port switch (some optical 1G ports, but mostly copper) and they want it to be able to operate in a -30C to +65C ambient.

The use case is outdoor protected/sealed, in a wide range of geographic areas.

Anyone by chance know of a manufacturer that sells such a beast?

Not particularly cost sensitive

Siemens RuggedCom is what you want. Plenty of options for configurations of power, ports, density, etc.

They aren't cheap, but they work really well.

Will this switch be completely stand alone or is there other equipment that will be going with it? Will it be in some kind of cabinet? For telecom equipment there is typically enough equipment in a road side cabinet that it actually keeps itself reasonably warm. Still get lot of low temp alarms in -40's but you can remedy that by shoveling snow over them. Very low tech but it works. 😛 Surprisingly I don't think I recall seeing them get colder than -5 or so. I have seen them hit +50 and over in summer though during heat waves. Typical enclosures will have vents that can be open/closed as well. Ours arn't automated so the techs go out and do it but I imagine you can get some cabinets where it's automated based on temp.

Example of such cabinet:

Even if it's just the switch you'll need some kind of power protection as well and room for batteries anyway so you'll probably want something like that.

We have cisco equipment here, 2950s, 2248s, 5548s and such and they run fine from -10ish to 45is celsius of course. Those never get really below that, but we do have some small cisco poe switchs that probly see in the -25-30 range a few times a year and they're holding up fine so far
