Power supply requirement for SM-ES3G-16-P

[Dmitry Podtikhov]

I need 3925 router and i want to install SM-ES3G-16-P etherswitch module with PoE into it. So my question is do I need PoE power supply or not? Will PoE ports on this module work with basic AC power supply?

Depends on your power supply.  Have a look at table-3 in this link:

Thank you for your reply. I've read the document, but it is still not clear to me though.

Document says: "Power over Ethernet requires the PoE versions of the router power supplies". I have two PWR-3900-AC power supplies in the 3925 router (not PoE versions). So I will have no PoE on the etherswitch ports? (despite the fact that there is enough power on this two power supplies to set PoE up)
