Cisco Systems DMP-4305G

[sasa.chetan]

I'm sorry but I have no experience with Cisco DMP.

I received a DMP 4305G-52-K9 but after starting it will show me the IP address (get it from DHCP) but after connecting through the browser (IP address name: admin, password: default) it will show me a white page.

I dont show firmware and DMP dont have a SD card. 
Is it necessary to have anything else to operate?
Is it possible to put alternative firmware there? (Tiny Core Linux or Colibri OS ?) DMP
Is it usable as a standalone player without cisco media ?
I have a NAS with FTP / DLNA / SMB on my network

Frankly, I would not put any effort into that.  
DMP 4305 is already end-of-support.  The firmware and documentation have been already been removed from public.
