Installing a TDM400P card with 4 FXO

good afternoon, please can you help me? I am installing a TDM400P card with 4 FXO. Elastix is not detected, my question is to the card with no q feed power cable 12? or only when plugged into the PCI port should work.


Since Digium hasn’t manufactured TDM400 cards since 2008, you’re likely installing a clone card. Clone cards are built by people that don’t develop or support Asterisk. :frowning:

The 12V connector on the TDM400 was necessary to provide ringing voltage for telephones connected to FXS modules. FXO modules do not require the use of the 12V power connector.
