A colleague and I agreed that there was very little information available on what is required for PoE on a Cisco 887, so I figured I’d document it for anyone else out there.
First things first, you’ll need to get yourself the bits you need. This comprises of two parts, a PoE power adapter and a daughter board. Both components should fall under the 800-IL-PM-2 part number.
Pop open the chassis (one screw on either side, and another at the back) and note the following location:
Insert the mounting risers into the holes outlined above and the daughter board just pops in on top. Screw it down and it should look like this:
Finally, connect the new PSU and power up your device. A show inv will list the PoE daughterboard indicating you’re good to go. It’s worth noting that if you power up the device without the PoE PSU attached the daughter board will still show up, but the additional PoE functionality will not be present.
To disable PoE on ports one or two, you can use the “power inline auto | never” command from the interface configuration context.
