Has anyone figured out how to power a Digium TDM 400P card in a Dell 1750 server? I opened the server and noticed that there is no access to 4 pin power to power the card. Is there some sort of adapter that I need to power the Digium card in a Dell Server? I see that the 1750 is listed on the Wiki. How have others powered the TDM400P in a Dell 1750? http://www.voip-info.org/tiki-print.php?page=Asterisk+hardware Thanks Keith -------------- next part -------------- An HTML attachment was scrubbed...

Yes, in most cases this would work. Unfortunately, this won't work as there are no 4 pin outputs from the Dell power supply to attach the splitter. Dell rack mount servers don't use 4pin power at all. The hard disks are hot swap scsi so they don't use 4 pin power. Also the power supplies are hot swap so the connection from the power supply to the motherboard is hardwired. I see that the 1750 is mentioned on the Wiki but haven't seen if there is some way that I am missing to get this to work with digium cards. Just curious as Dell rack mount servers are fairly commonplace and would be surprised if I am the first one to hit this problem. I called Dell and they said that there is no way to obtain 4 pin power from their servers. I am hoping that someone came up with a way to build a custom wiring harness that would allow for this. ------------- Have you no way to use one of those power "splitters"?

If you don't have any fxs modules, the connector is not required. If you do have fxs modules, find another lead that supplies regulated 12 volts and tap into it. (Shouldn't be hard as the MB connector has the 12 volt going to it somewhere.) Only that single conductor is needed; ground is handled through the pci edge connector.
Ok, makes sense. I obviously have one of the newer TDM400P cards since it does have the power connector. However, I only plan on using FXO ports. Will the card work without external power if there are only FXO ports? Thanks Old TDM400P cards did not have a power connector. The new ones do. The power to the card is required on any card that has a power connector. The modern TDM400P cards are the only Digium cards that require external power (since they are the only cards that support analog FXS ports and those ports require more power than many motherboards can provide via the PCI bus) -------------- next part -------------- An HTML attachment was scrubbed...
