Help me troubleshoot this card please

Brand New TDM400p installed. when the pc is turned on will yhe green LEDS come on…anyone?

It would be helpful if you’d expound on what’s happening and what you have. Is the card configured with FXO or FXS ports?

The LED’s should light when the box powers up. If you only have FXO ports (or have ANY FXO ports) you need to power the card using one of the 4 power disk drive power connectors. Did you do this?
