Re: [asterisk-users] Electric usage of a tdm400p
Erick, It looks like the 2.5 laptop drive requires 5 watts to spin up. Adding that to the 15 watts for the Digium card, leaves about 40 watts available for the MB. It's unlikely that the system will be producing ring voltages when the drive is spinning up. It depends on how conservative you may be with real-time power management, e.g. spinning drives down when not in use, etc. I did not easily find too many ITX MB power requirements, but the one I did find, required 45 watts (peak). In the worst case, ringing 5 RENs on each Digium port and spinning up the disk, you would be overtaxing the power supply. I doubt you will have 5 RENs on each port and all ringing, but you could. In ages past, hard drives were the most vulnerable to poor power regulation, but that may have changed. With the higher cost of 2.5 drives, I would not take any chances. Beefing up the power supply would also eliminate the need for manually managing power should you need a CDROM or more power hungry drive in the future. It's also one less concern when troubleshooting the system. As Moj has pointed out, problems can occur when working close to the edge. I, too, have experienced similar problems when power was limited and have had to, temporarily, resort to a bigger power supply to get a system installed. Then fell back to a smaller one in operation. Good luck. Bob... On Wed, 2006-10-18 at 08:49 -0800, Mojo with Horan Company, LLC wrote: I set up a similar system on an VIA Epia 5000, and I had issues when I included the CDROM in the mix.

I presume you could install the OS with the CDROM drive installed and the molex power connector REMOVED from the TDM card, then when the OS was installed and you had network connectivity, power down, remove the CDROM, add the power supply for the TDM card, then install zaptel etc. Or just try it and tell us what happens, low power won't break it in my experience. Your cdrom drive might have a lower power consumption than mine.

Erick, Per http://en.wikipedia.org/wiki/Ring_(telephone) in the US the ring voltage is around 90VAC (20 Hz) with a current of 30 milliamperes (REN ~5). This translates to 2.7 watts. Assuming a DC/DC converter efficiency of 38% (probably low), you would need about 3.7 watts, per FXS module. About 15 watts, total.

Re: [asterisk-users] Electric usage of a tdm400p
Further, I should have mentioned my resolution. As Bob mentioned, upgrade the power supply now to give you options and peace of mind in the future. I am using a picoPSU-120 in the aforementioned itx box, for example, http://www.mini-box.com/s.nl/it.A/id.417/.f?category=13 and have been quite happy with it :) Moj Bob Chiodini wrote: Erick, It looks like the 2.5 laptop drive requires 5 watts to spin up.
