I'm looking to buy several small wall mounted UPS's to power a telco's metro ethernet switches. (Yes, they should have provided some kind of protection, but won't).

The closest suitable UPS I've found is this:

Can anyone suggest a better alternative?

I want something sturdy, preferably metal, that can screw to a wall and be worry free for years at a time.

Any UPS will have batteries, probably sealed lead-acid for a small UPS. That is likely to negate "worry free for years at a time", especially if wall-mounted in an unconditioned demarc/MPOE closet as opposed to a temperature-controlled data center. At a minimum, plan on an annual visit to do routine maintenance and load test the batteries. You'll be lucky to get more than three years of service out of them. A typical Chatsworth, etc. 19-inch rack shelf available in various depths can be flipped around and screwed to a wall to support many of the stand-alone UPSes. -- Jay Hennigan - CCIE #7880 - Network Engineering - jay@impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV
