If its temp controlled then how about humidity controlled? I would ground the rack and the chassis.

However in real critical sites of severe cold we have had great success with the 2524m. However, none of this means anything if your temperature is controlled. I would call HP and have them send you a replacement. They are really good about it. 800-474-6836 Thank You, Cameron Kilton Broadband Department Assistant Systems Administrator Midcoast Internet Solutions http://www.midcoast.com/ [EMAIL PROTECTED] (207)594-8277 ext. 108 ------------------------------------------ High speed internet access on Islands?

We have 40 or so switches like this, and it only seems to happen at 2 or 3 locations (the most remote ones, of course). Travis Larry Yunker wrote: Travis, Is the switch in a temperature / humidity controlled environment or is it sitting outside in a relatively uncontrolled NEMA enclosure? I've seen a lot of switches die during cold weather when run in NEMA boxes. Keeping the box above freezing seems to resolve the issue in most cases.

This is during the middle of winter, when there is no lightning or any other static electricity. We simply move to a different port on the switch and everything is fine. We have protected PoE injectors (Pacific Wireless) with grounded power cords. We are using HP Procurve switches. We usually have a 3ft patch cord between the injector and switch. Is there any particular brand of managed switch that handles this type of issue better than any others?
