Thanks !

Good luck. After bitmain intentionally gimped the S4+ via firmware I asked them to provide the original so I could revert. Got a lot of "were working on it"  emails, but never any actual results.

I highly recommend others take my philosophy on Bitmain updates on miners that don't use SD cards and can't be reverted easy (C1, and S4 both were great with SD).   

My motto is if it's the miner is working good and no big issue update, or big feature release.  I would just keep the current.  If it works great... not always best idea to change.

any way to get this original FW file the new file from the site just broke my miner

My five hours offline was due to a crashed Internet.
I was away for weekend and got back seven pm tonight.
We had something in common my s-7 was set to manual fan speed.

Like you

I am using the firmware originally supplied with the two units. 1.5.3.0, file date September 15, 2015.


So manually setting may allow for safety

I think the manual fan setting is the 'fix'.

TY for testing

Thank you very much for your time, investigation and sharing your findings with us.

Just tested loss of internet with my batch 1 S7 and my batch 3 S7. I run with a proxy to combine all my miners to a single network connection.  This runs on a local machine.  I left my LAN connection from the two S7's to this machine.  Then I disconnected by DSL link. I continued to monitor the S7's with their web interface. 

For the first 10 minutes, the proxy continued to fool the miners that all was well.  After about ten minutes the S7's started beeping.  Checking their status, both showed the connection to the proxy server as dead.  The 5 second hash rate dropped rapidly.  Both S7's have their fans set on manual speed at 40%.  I left things this way for another five minutes, observing that the fans continued to spin at their normal speed.  The chips cooled down.

After another 10 minutes, I reconnected my DSL service and established pool connectivity.  Within about a minute, both S7's were back to normal, showing a connection to the local proxy and the 5 second hash rate building back up.

If there is an overheating safety problem with the S7's either:

1. It does not affect my two units
2. It is intermittent and may hit my two units some time in the future if there is a network outage
3. I may have bypassed the problem by using the fixed fan setting.

I am using the firmware originally supplied with the two units. 1.5.3.0, file date September 15, 2015.

I upgraded my miner to latest firmware now it will not hash and network diagnostic ping test fails any advise BITMAIN?

Maybe try setting fan to manual at 100 or 99

Any workaround with the manual fan setting?
I'll be getting two Wednesday I believe. Have to configure at home.
Don't like the full speed running miner fan to just kick down when you hit "apply" on the configuration page.
Has to be a bunch of heat just percolating in there when the fan kicks down.
Maybe high ambient temp would cause too much heat.
I think they are trying to get ahead of things, heat/wattage, etc.

I lost my net today and did not fry my s-7 so why did I work after five hours on bring offline.

I did not do different firmware.

Thanks for your post. But I'm still not completely clear on this issue.

Can you verify that the new S7 firmware fixes the problem where losing internet connectivity can cause damage to the miner?

Many of us are not in a position to have a second ISP. We have no control over whether or not our Internet connection will be reliable.

It's important to know for sure that this problem is corrected.

Thank you in advance for clear communication on this issue.

You guys still have not fix that issue??

For oversea market, we only shipped out a very small amounts of 4.66th/s miners to customers in Batch1. If you didn't get the email from [email protected] to confirm the 4.66th/s miner issue before, it indicates your miner is with 4.86th/s and you should use the 600M, 4.86th/s firmware directly.
for 4.45th/s miners, it's for domestic sales.

Thanks for the update, BITMAIN WARRANTY.

Tracking Number should be emailed to you from the automated system when the factory ships your Antminer.

if you purchased the PSU and the miner at the same time, your PSU may have been shipped ahead and the order may be marked as "shipped", however, when the S7 ships, the system will update and add another tracking number belongs to your S7.

Some had the tracking numbers updated in the system, but the automated email didn't make it to the inbox.

and....

Regarding the Internet Connection to your mining farm or Antminer S5, S5+ and S7, please make sure you do not loose internet connection! (2nd ISP will help you avoid that problem)

For S7, new firmware is published at http://www.bitmaintech.com  Please select the correct frequency version you originally received.  If you received 575mhz version, please use the same version.

My tracking was posted the day the order shipped, Friday... Received today..

So, is the only way we know our order shipped is when the truck pulls in or an email from FedEx/DHL/UPS?

LOL
