Birch UPS


Had the job last august or so to install a LAN upgrade at Birch. They overlooked the power requirements for the new Switches and Routers. Which normally means Uninterruptable Power Supplies. For something like this, with a pair of DS3 feeds supporting a few dozen VoIP users, the UPSs are Liebert 2000's with an extra 48v backup battery. About 400 pounds. They finally noticed that they dropped the ball and I'm finally finishing the job.

The UPS I'm mounting in the patch rack, inbetween the router and switch racks. The supplied shelf is mounted on the rear of the rack (left picture) so that the UPS will be not sticking out in front and will have the weight mostly centered on the shelf. No problem, 'cept that they slide a little. The supplied brackets would hold the UPS off center on the shelf, so I had to make my own brackets. Had usable brackets that were to hold the Ungermann-Bass Access One (yeah! Look up how old THAT is!) in an older 23" rack (actually a List-15 Data Cabinet.)

Pete Talaro, relaxing in paradise, was The Man when it came to making the shelves and brackets we need to do the job to L.A. Harbor OCS standards. The first backet took a few hours, including time spent working/closing tickets and destroying a couple of attempts. The last two brackets only took about 15 minutes to drill and mount -- once I figured out how. But the resutls are GOOD! (see right.) The UPSs and their batteries are rock solid. Which is a good thing -- Birch is rather close to the Newport-Inglewood Fault.
