Re: [WISPA] Dual Power Supply, how to?
Just a quick follow up. A quick search of the internet shows up a lot of devices. (APC makes a few different types). These are either called Dual AC Automatic Transfer Switch. Or depending on your voltage needs, you could modify an Dual AC power supply module for Computer Or find a AC to DC rack mount powersupplies used in Telco's .

Re: [WISPA] Dual Power Supply, how to?
Not necessarily - your goal is to keep it powered 100% of the time. What part seems to go bad for you most of the time? The power supply, PoE, DC jack, power company/UPS unit? If the power supply on the board goes bad you're SOL, sorry. You'll have to find another product. If the PoE or DC jack goes back, you need to get both of them powered. If you have the power company and UPS go bad find a second source of power (generator?).

Re: [WISPA] Dual Power Supply, how to?
I would agree, it is very easy to go overboard and over engineer to the n'th degree, however if you do that you will find that you would be introducing more elements which would cause a negative effect. E.g. Heat and power consumption... Coming for the wired world, where only now folks have started to pay attention to power comsumption and heat generation as being a bad thing.. I consistently amazed to see some very 'powerful' wireless equipment working with a 'wall wart'... It takes a bit for it to sync indue to the low power consumption that is all what is needed.. Moral of the story: Very easy to get carried away and over engineer, but doing it within reasonable limits is the right thing to do. ... Just me two cents.. BTW: I have one of the APC redundant power switches, purchased it, thinking it would be a good thing to use... But never put it to use... Don't need it in a Data center ! -:) Faisal Imtiaz Computer Office Solutions Inc. /SnappyDSL.net Ph: (305) 663-5518 x 232 -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Josh Luthman Sent: Friday, October 24, 2008 10:42 AM To: WISPA General List Subject: Re: [WISPA] Dual Power Supply, how to?

Re: [WISPA] Dual Power Supply, how to?
We currently use DC power supplies, but non-redundant http://www.solaheviduty.com/products/powersupplies/sdp.htm. We use terminal strips to distribute the power. For us to change, we just replace the power supplies with this... http://www.solaheviduty.com/products/powersupplies/sdnpred.htm. That has the rectifiers and diodes in place with LED status indicators to show the status of the power. Then you can put them in parallel and put 2 UPSs in place for failure and surge suppression.
