Hi, Running a bunch of CentOS servers on 2U supermicro equipment, usually with 8 drives on Adaptec SmartRAID V or LSI Megaraid. In designing a rack in a data center, the question arises as to how to measure the amperage the server uses, prior to investing in power drops that actually do that for you, even remotely, for about $260.00-300USD per unit. This number is the important one these days in determining rack/datacenter design. So the geek question is, "what do you use, from radio shack, or elsewhere, t...

Guess who's here to do an Asterisk demo this week without the power supply for his SPA-841. I have an ATA186 with me. Both phones use a 5v supply. Does anyone know whether the supplies are interchangeable? Thanks in advance; sorry for the noise. B.

However it seems the 'phase shift' usually refers to lag between Amperage and Voltage waves, while this issue is (if I get it correctly) about two separate ATS inputs fluctuating on their own different clock-offsets. Should be same freq (50 or 60) though, or likely assumed so - which might not be guaranteed in real life either ;) On the other hand, if the freqs differ,...

Hi all, here is another one, related to ATS (automatic transfer switch) this time. in order to track "dephasing" between input sources (1 and 2), I'd like to add a new variable: "input.phase.shift" Details and implementation can be found on: https://github.com/networkupstools/nut/pull/433 Comments and feedback warmly welcome. cheers, Arno -- Eaton Data Center

I posted a thread here... http://forums.opensolaris.com/thread.jspa?threadID=596 I am trying to finish building a system and I kind of need to pick working NIC and onboard SATA chipsets (video is not a big deal - I can get a silent PCIe card for that, I already know one which works great) I need 8 onboard SATA. I would prefer Intel CPU. At least one gigabit port. That''s about it. I
