S7 beeping and RED LIGHT AND INTERNET ISSUE? Please help? newbie

[trynaEat2]

I AM SORRY IN ADVANCE IF THIS HAS ALREADY BEEN POSTED AND ANSWERED- I TRIED TO SEARCH BUT GOT LOST IN OTHER THREADS OF GREAT DISCUSSIONS...

I have an S7 that overheated and then when i powered it back up i couldnt get the miner onto the network.. seems like the ethernet port may have burnt out there is a beeping noise and instead of a green blinking light its now a red blinking light...

any advice would be helpful, im crying at night seeing the price rise of BTC and this miner just idling around...

Can this be repaired... sent back is it worth it? can i salvage the chips?
i have S5s but they are slower than molasses and loud and hot. it is difficult to leverage them and power them at same time.

Have a S7- working 4-THS  A R4 WHICH SEEMS TO BE THE BEAST OF THEM ALLLL QUIET EFFICIENT NOT USING A LOT OF PSU... SHOULD IT USE MORE PSU-- SHOULD I RAM UP THE FREQUENCY ON THAT ONE??

R4-~5TH/s

s5 500gig hash-- am i supposed to update the firmware on these at all or anything-- or just straight plug and play??

Thanks in advance!!

Im just Tryn 2 Eat 2!!

With Bitmain beeping most often means no network connection but might be overtemp warning. The fans working? If not it will very rapidly overheat and stop the boot process causing the same thing.

Unlike the S5 and earlier models the chips cannot be salvaged -- the heatsinks are held on with thermal epoxy and are extremely difficult to remove without damaging the chip.

The problem is depend on your home internet that have only dynamic ip address but you have setting up Antminer S7 by (x) static ip. When S7 is using static ip address it has to use your Internet provider DNS + Gateway that not allow you to use static ip address. If you turn off (untick) static ip address in S7 setting is will be ok again.

Better if you can apply to get a static ip from your home ISP. I am paying $7/m extra to get static ip address for my Bitmain Antminer s7.

This is 100% false. Removing the heatsinks carefully is not all that hard. I can pull an entire board of S7 heatsinks off in 20 minutes without damaging the chips. The secret is to heat the smaller bottom heatsink and pull it off first. If you heat the larger heatsink it will pull the heat through to the bottom heatsink and melt the solder holding the chip in place, causing you to pull the chip off along with the heatsink in most cases. Also make sure you are not pulling straight up on the heatsink, twist a little when pulling so you are almost rocking the heatsink back and forth and peel it off slowly.

Whatever you do, do NOT follow these instructions. This guy is giving his machine an EXTERNAL IP with his setup leaving it completely vulnerable and open to the public internet to be hacked.

The beeping is due to it not sensing internet. It can be a number of things. IP conflict, DNS issues, bad network cable, etc. I would verify all settings as well as swapping with a known good cable. Also you might want to factory reset the controller in cause something got borked in the configs. You can do this by using a toothpick to push in the reset button to the right of the ethernet port. Hold it down until you see both red and green lights blink at the same time and it beeps. This will put it back to DHCP so you can then find its IP, browse to it, and put all of your settings back in.

Gotta keep in mind the general audience here... Given the posts we've seen folks make most have minimal to zero skill sets for this.
Even then, good luck reusing the s7-s9 chips. Even Sidehack refuses to deal with them because of their insanely fine lead pitch.

Fair enough. I did learn how to repair the boards and have managed to reuse s7 chips on other boards successfully. The biggest issue is not knowing if the chip you are pulling off of a board is fully functional or not but it is possible with basic hand tools.

Do I say somewhere that my S7 has an external ip?!
When you (x) static ip address on s7 setting (e.g. S7 has –x- for a static ip 192.168.0.27, from e.g. Adv. ip Scanner).  Antminer has to run a specific static ip 192.168.0.27.  But ISP, for some reasons many ISP for home internet are not allow any customer home pc has static IP, but only running with dynamic ip. Antminer is beeping cause of networking ip conflicted. It is conflict with ISP domain name system (DNS). In this case it has nothing to do with bad cable; resetting Antminer … I learned to known these conflicts since Antminer s3 with Windows XP.

My extra static ip that I ordered from ISP has accepted Antminer static IP 192.168.0.27 and another static ip that Antminer has chosen in all of my Antminer that they are mining. And easy when I have to recounting them to pool.
