Hi, I just put a 9-Port HWIC-ESW Power Daughter Card in our 2821 router and have configured the ports for the appropriate voice and data vlans. Data connectivity is working fine however the phone is dead in the water (no power). The show diag has this listed as a 9-Port HWIC-ESW Power Daughter Card so I am assuming this should be POE. Is there any special commands needed to get power or anything I can check to see why this is not working.
You also need the PoE power supply, do show env and you will see that you do not have it.
Always double check before buying Cisco hardware, often things are not so simple as they seem.
