these last few rigs seem to be the dregs of the old farm...
I wouldn't mind if it was functioning as 'expected' but this is my 4th lemon in a row.
My last 2 detailed emails have either been ignored or replied to without being read/understood.
i explain clearly that swapping the IO board did nothing and it seems to be a heat sensor issue.
the reply was 'return the faulty hashing board'
i appreciate they must be busy in BMHQ but a just delivered, overheating rig which can presumably be diagnosed pretty easily should take some kind of priority.
if i hadnt used the advise of someone earlier and aimed a huge fan in there i am 100% certain something would have melted/fried by now!
E2A - after only 46 hours & innumerable emails, Bitmain has agreed to send out a replacement power board (back plane) tomorrow

STILL suffering an overheating rig!
swapped IO board with functioning rig to no avail...
anyone have any ideas?
A schematic would be nice... particularly interested in heat/fan sensors location
I think its posted on the github antminer repository.swapped IO board with functioning rig to no avail...

Hi ,any experians , how much we can get per day BTC with this toy, difficulty rise again ?
At these BTC prices ~$9/day (~0.014-0.015BTC) vs ~$1.1-1.2/day in electricity if at $0.12/kwh.
Thanks
im scared to power on the orig PSU after the pop and spark, ill test it when i get home later
also, the 10th hash board when plugged in the S2 doesnt even turn on.. does that mean the hash board is fried? the remaining 9 seem to work fine

Please do'nt use the psu if you hear a clear pop and saw a spark, this means probably that your psu is broken and the fuse burned! You can try powering it on again but be safe and know what you are doing. Please use your new psu if you are not familiar with electronics.

Try removing all the hash blades from the S2miner, and only boot the miner with the main board and the original psu. Can you reset the miner using the button on the front and login to the default web interface (192.168.1.99) ?
p.s. the white glue / epoxy is normal in psu's and should not affect the workings of the psu.

but at this point its pretty obvious what the issue is lol.
That white stuff has nothing to do with the capacitor unless I'm blind, it's the normal glue they put all over psus to stabilize stuff and reduce coil whine.
Is there anyway to change the web interface password trough ssh? and how to change the default root/admin login for ssh?

my latest S2 died lastnight, was only running for 12 hours since it was delivered at my house yesterday.
i was checking my pool stats in the middle of the night while feeding the baby and noticed the new s2 not hashing so i went out to the garage and the power supply fan is spinning, but the s2 is dead, no lights at all
so i turn it off and on to no avail, then unplug it and move it to a different outlet and plug it back in and there was a loud POP and a spark flew out of the power supply. upon closer inspection one of the capacitors blew and is leaking white stuff
had a spare 1000w rosewill psu i swapped it with and started up the S2 and wouldn't turn on agn, so i started removing hash boards and moving them around and came to the conclusion one of the hash boards is totally dead. when this particular board is plugged in the unit wont turn on, doesnt matter if theres 6, 7, 10 boards plugged in. without the dead board the S2 starts like a champ
the unit is now running fine with 9 boards and my spare PSU
contacted bitmain for RMA help and so far theyve asked me some troubleshooting questions, but at this point its pretty obvious what the issue is lol.

Other solution :
Remove the bad board
Overclock the S2
Run the Overclocked S2 with only 9 boards
I will have the same hashing speed as 10 boards

What frequency are you running? I facepalmed myself just now for not thinking of this!
option 'freq_value' '0801' #212.5M
option 'chip_freq' '212.5'
option 'timeout' '40'
Cheers for that--I'll give that a go when I get a chance this week. I'll let you know how it turns out.
i cant actually access miner config / miner status without pulling th ether cable and connecting straight to the laptop.
i CAN access network & system without issue but they reveal little info.
Repeated requests for tech support have gleaned nothing.
the 67C is showing on the LED display & in PuTTy, but i cant tell much more.
when i power cycle it sits around 60-61 for a while but the fans continue to drop, rev up, drop, rev up until it gets up to 66-67C
on opening i found 1 blade not hashing so i pulled it, swapped with another to check if it was the board or the connector and when fired up all 10 were hashing.
which leads me to thinking its the (temp sensor? on the) powerboard, not the fans themselves.
E2A - Fk me, shes at 72C now!!

Is the miner status reporting the same 65c temps across all the blades? Does it report the RPM on all four fans correctly? If the miner thinks a blade is 65c I think it is going to request full RPM on at least one fan if not all of them.
65C is really hot, My S2 runs stable at 40 degrees with intake temperature of 32 degrees. I really think something is wrong with the temperature measurement or your fan settings. First thing to try is to reflash your mining software / firmware with the latest from bitmaintech.
Advanced (not recommended) tip: Set fan speed to 100% all the time to make sure the unit never gets to hot. You can do this by opening the unit and strip the blue or white cable from the fan cables leading to the mainboard. Only do this if you are familiar with electronics and computer equipment.

Also rcvd an S2 today after customs held it for 24 hrs.
fired up ok, shame about the shoddy lid with no 'tongues' to keep the side flaps down.
HOWEVER, the fans are acting up in as much as they power up, & up, & up then cut out
then 5 seconds later they power up, & up & up then cut out again
then 5 seconds later they power up, & up & up then cut out again
then 5 seconds later they power up, & up & up then cut out again
shes hashing around 1000 but the noise is giving me toothache right now its been at it the whole time its been running.
i tried removing the metal plate to see if it made any diff and it didnt.
shes also running 4-5C hotter than my other 3...
any ideas??

Direct a moderate extra fan airflow toward the intake fans; it seems to help to reduce the internal fan's speed, hence noise.
Lower ambient temperature in the room helps as well...
