My current task is to install asterisk utilising a TDM400P in a Dell Poweredge 1750. This box doesn’t have the usual molex style power connectors required to plug into the TDM400P. One of the connectors on the motherboard has 12V, GND and 3.3V available which I can splice to provide the needed power.
What are the power requirements for the digium TDM400P through the power connector? Does it only require the +12V (and GND) connected, or does it also require the 5V supply?
Thanks for any help.
