1) upgrade to the latest firmware.
2) Try another PSU
3) Check boards/Fans.

Hope it will help you.

How can I upgrade to latest firmware as I can't even access the machine through IP or LAN.
I have checked with several PSU as I got 22 Antminer s7 from first batch.
Fans and Boards seem to be working fine but can't access the machine as it doesn't connect to the LAN or doesn't assign the IP to access the interface.

Already sent an email to BITMAIN hope to have this solve soon

never never never never do firmware upgrades 80% of bitmaintechs firmware upgrades were bad.

I would not even mess with updates unless there is a big security issue, or big feature addition. It is just risk in most cases for not much. If it works why mess with it?

But phil is right never stop or close window during firmware update. I have had one power issue on S3 during firmware ... and it made a brick. Ever since then I'm very careful on updating. I'm guessing they have you send in controller and they ship one back working. Depends on if you have warranty still on the price.
