Raspberry first time, what's the problem?

Question

Raspberry Pi

Hello. I ran into a rather interesting problem.
I have a raspberry pi 2 board and due to some circumstances I cannot connect it to the monitor for the initial setup. I found a lot of manuals on the Internet for the initial setup via SSH, but the question is that when you connect the raspberry with a patch cord to the router and start it, it does not see the patch cord, the indicators on the ethernet port do not blink, the router also does not see the raspberry . It is worth noting that 3 different obviously working patch cords were used, raspberries could not cope with any of them, what to do?

Answer 1

Is the memory card alive? Try another card, another system image, another power supply, another power cable (maybe this section is not enough).
The network rises almost last.
