[asterisk-users] FXS, Power and Sangoma

[Tim Nelson]

That does indeed sound a bit odd. I've run 12-48 FXS ports from a single molex connector with Sangoma hardware. Try testing your power supply with a multimeter to ensure its putting out the proper voltage. I would not trust the extnernal AC adapters as I've found they typically have voltage that is too low...

Hi
   I've a Sangoma A200D with 2FXO and 2FXS.  When using it with only  
the FXO module, it's all good.  But when I put in the FXS module and  
connect the power, logs tells me not enough power.

So I disconnect other power devices in the box (Dell Optiplex GX270)  
such as the Zip drive and CDROMs, but no luck.  Then I took an  
external power supply with molex connector (http://www.coolerguys.com/840556029977.html 
  or http://www.cablesonline.com/mo4inpotoacp.html) and tried that  
with still the same thing.

How much power does this card need?  The AC adapter puts out up to 2  
Amps.  Sangoma support is only telling me to get a bigger power supply  
and don't use the AC adapter.  Has anyone else seen this issue?  Could  
something else be wrong?
  thanks
    Todd
