Author Topic: Dolby DSS-200 power supplies Stephan Shelley Jedi Master Film Handler Posts: 854 From: castro valley, CA, usa Registered: Nov 2014 posted 02-05-2015 05:28 PM                     How are others DSS-200s's power supplies holding up? I have lost 3 in 4 months. 2 in one server at different times and just now 1 in a different server. This last one made a big pop when it powered up.  |  IP: Logged Marcel Birgelen Film God Posts: 3357 From: Maastricht, Limburg, Netherlands Registered: Feb 2012 posted 02-05-2015 05:48 PM                     There have been a few bad batches of those particular Supermicro PSUs with caps failing after a while, especially the older generation. Often, when the first one fails, the other will swiftly follow. Maybe they were a victim of the Capacitor plague. But in general, the newer ones seem to be pretty stable actually.  |  IP: Logged Stephan Shelley Jedi Master Film Handler Posts: 854 From: castro valley, CA, usa Registered: Nov 2014 posted 02-05-2015 06:16 PM                     The two servers are a few months past being a year old. They were new when they came to us but how long before that they were manufacturer I am not sure. Power supply was made by Ablecom. guess they supplied Super Micro. Says it is made in China.  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 02-05-2015 06:35 PM                        We have two DSS200s, with 2009 and 2011 manufacturing dates. As far as I'm aware, both still have both the power supply units that shipped from the factory.  |  IP: Logged Marcel Birgelen Film God Posts: 3357 From: Maastricht, Limburg, Netherlands Registered: Feb 2012 posted 02-05-2015 06:40 PM                     quote: Stephan Shelley Power supply was made by Ablecom. guess they supplied Super Micro. Ablecom is the "OEM" brand name of Supermicro. You will notice their logos rather look alike . They are made in China and/or Taiwan, but then again, what's not made there nowadays? It seems you had a bit of a bad luck there. Obviously you could check for common factors, like the same brand of UPS being used on all of those. I've seen rare cases where UPS and equipment PSUs just didn't like each other, probably because of the bad quality of the output power of the UPS and/or the rather non-resilient design of the PSU.  |  IP: Logged Stephan Shelley Jedi Master Film Handler Posts: 854 From: castro valley, CA, usa Registered: Nov 2014 posted 02-05-2015 06:57 PM                     No UPS here. And we have a DSS/DSP 100 powered by the same power panel as the one that just went that has been running for almost 7 years. All get the breakers turned off at night.  |  IP: Logged Marcel Birgelen Film God Posts: 3357 From: Maastricht, Limburg, Netherlands Registered: Feb 2012 posted 02-05-2015 07:06 PM                     The breaker aspect is an interesting one. Mind you, those things are actually server power supplies, they're designed to run 24/7 and switching them on and off regularly might even cause more wear than just letting them run, even in stand-by mode. Another thing they don't like is dust and oil, they were never designed to operate in a rugged environment, but rather in a typical IT room environment. If they get clogged up, they tend to overheat and just blow out once in a while.  |  IP: Logged Matthew Ortado Film Handler Posts: 20 From: Halethorpe, MD, USA Registered: Jan 2010 posted 02-05-2015 07:15 PM                     We have had one or two that have failed out of over (200) DSS200 systems.  |  IP: Logged David J Hilsgen Expert Film Handler Posts: 192 From: SAUK RAPIDS,MN .

We do use a UPS and rarely power the server down  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

I don't have the models committed to memory though. Watchout on some of these suppliers, I've received used being passed off as new.  |  IP: Logged David J Hilsgen Expert Film Handler Posts: 192 From: SAUK RAPIDS,MN .

Knock on wood no problems with power supplies yet. Can not say the same for our CP750s, have lost a few of them.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 01-18-2016 05:45 AM                     I had boatloads of CP-650 supplies fail form the plague.

Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 01-18-2016 06:00 AM                     I'd say that of the 200 or so DSS200s we have out there...maybe 5 of them have had any form of power supply issue. The power supplies require no wiring. They just slide out as a self-contained brick.  |  IP: Logged
