Just installed a TDM400P card in Asterisk@Home 1.1 Should the LEDS on the back of the card light up? Yes, I have to the power connected to the card:)
The LED’s light if:
You have installed the card,
You have conected the 12v power cable,
You have an FXO or FXS module in the corresponding slot,
You have installed, configured and started the Zaptel software.
Until you do all four of the above steps, your LED’s will not light.
