Cisco 881 PoE installation troubleshooting

Hello,

I recently installed a POE daughterboard into a Cisco 881 ISR. However, I can't seem to get power running through ports 0 or 1. It seems to be assembled and installed correctly, but I'm not 100% sure anymore as I've been struggling with this for awhile. Any help would be appreciated.

Make sure you have the right

Make sure you have the right power brick, don't have details at my finger tips but there's a higher voltage model for the PoE functionality (depending on exact version of 881).

I have the normal power cable

I have the normal power cable plugged in, as well as the higher voltage for the PoE as well. So two power bricks plugged in total.

Remove and reseat the POE

Remove and reseat the POE daughter card. If it is still down, replace it.

Also it is important to know how much wattage your ip phone needs to power up.
