I noticed something didn't seem right with the system though... See if you can spot what I assume was an assembly error at the factory: Need a better hint? You can imagine how well that worked...

I think it was one to suck in outside air and the other to evacuate air circulating over the power components.

Considering how hot everything was getting no, I don't think it was set up correctly. All the fans were doing was recirculating the same hot air across the power supply. I called Hoosier's and they confirmed both fans should be blowing out, which is how I set up my system. The cabinet is much cooler to the touch now, and I can only assume the boards inside are as well. -J Last edited by compu_85; 08/06/14 12:29 AM. Jason Perkins Network Engineer

I remember this because I had about 5 I had to go out and flip the fan on.They ran hot but they worked so no problem as they were only in service for a few months before I got the bulletin.

Also having the bin file may come in handy Jim Hoey SST Communications 597 West Montauk Highway Lindenhurst, New York 11757 631 956-0100 www.sstcom.com Business telephone systems on Long Island and New York City like Comdial, Vertical, Avaya, Panasonic
