951Ui-2HnD v6.0rc14 + Sicso SPA504G poe not work

Good day, everyone,
recently i purchased 1 mikrotik router board. 951Ui-2HnD

It works ok. But later i connect to it my Cisco SPA504G ip phone, like this:
http://www.cisco.com/c/en/us/products/collateral/collaboration-endpoints/small-business-spa500-series-ip-phones/data_sheet_c78-548564.html

and nothing changes. Phone not light up. So, AFAIK, this switch by default does not running poe on its eth5 port/interface.

Is it possible to powerup this phone by this router?

What command should i use to check details? And to activate poe on ethernet 5 port?

Does this router and and IP phone compatible with each other?

Thank you.
