Topic: v2 Blade, asks for work 8x, then nothing (Read 1069 times)

how did you do this ?

All 4.  and I note bringing power to the slot connectors didn't fix it.

ok
but how is it wired ?
just 2 pins useed or all 4 ?

Standard L connector that came with the Blade.

ok
can you post a pic of the power connector you are using ?

I have tried resetting.  Will try again.

And the results:

I'm not ready to  disagree with you about it being a power issue.  I would like to try connecting to the slot pair of contacts instead of the L.  Without having a backplane how would I simulate a backplane connection?  Anyone know where something similar is used that might be exploited?  Given the current, car jumper cables perhaps.

Okay found something.  Not quite jumper cables.  I bought a solar car battery charger to top off the battery driving a drill motor spinning a threaded rod raising and lowering the chicken coop hatch on a timer - protects the chickens but allows them out when predators are scarce, after dawn.  It came with large alligator clips.  Although the wires aren't too heavy, using those in parallel with the plug, the L plug having 4 leads each good for 15 amps, if there were some resistance at the plug, it might allow the ASICs to change to O's.  It didn't.  So, unless the power problem is at the fuse, resistance of some kind, which wouldn't change anything using the clips to the slotted positive and negative, perhaps there would be a hot spot I could measure with an IR thermometer at the fuse.  The ASICs do get warm but don't show O's........measuring............ASICs at 116°F but the fuse at 95° and the L plug at 85°.

that's a power issue
I have 30 + blades
all running ok no problems
have you tried resetting the blades and setting it back up again

Interesting.  When I click Switch Server, I get this: Current Server: :19501

Two supplies in parallel are no help.  Same string of x's.

I feel bad.  This Blade had been running for 4 days shy of 3 months.

Now the problem is that no ASICs are working.

I have 1.something volts across the copper pads near the coils.  So I assume the ASICs are getting  voltage.  There isn't a fuse on the 1 volt supply as well I suppose.

There is no indication on the proxys that any communication to them is taking place however the configuration web page is up.  I did manage a factory reset and accessed the webpage at 192.168.1.254:8000 and did change the configuration to have the proxy addresses.

Refreshing the configuration tells me the miner has been up 5 minutes, zero hashing, no asics, all x's.

How long is one suppose to reset these for?

slush


Okay, now it's different.  Cleaned the board, started it up, a quick 40 or so getworks and 28 accepted's now it says no aSICs at all, all x's

tried different pool?

Are you using bfgminer proxy or slush's proxy?

I got the same issue, board resets every 2 minutes 2 seconds. Tried 3 different power supplies, one brand new with 600w PCIE connector with multiple wires. Does yours shut down exactly 2 minutes? where did you buy it? I heard of one other user having this problem as well. I am returning mine for a refund.

Welp, a replacement power supply was in my post office box today.  Just got back.  Swapped supplies.  Fired up.  No change.  Shut it down,   Took a high speed 4 port switch I have half way across the room for my WDTV, put that to the gateway router with a short cat5 jumper, ran the Blade to the newly placed switch, watched the proxy, it quickly ran off 40 get works and just as quickly came back with 28 accepted, then it stopped.  Sitting dead.  Asks for new work, I look at the configuration page and it has rebooted.


ASICs all "O".

When I reset to factory defaults and it didn't, I had the cat5 out, power off, jumper to the ground/factory_reset pins, fired up, watched the flashing LED, same one as the regular reset, shut down, took the switch off the reset, rebooted and it still had the previous IP address which tells me it didn't reset.  

12.1VDC.

voltage?

My Blade stopped working.  It's to stratum-mining-proxys.  On either one the same thing happens.  I fire up the Blade, it requests work 8 or 10 times and then nothing.  This last time it asked 8x, then ~14x then submitted, got a single accepted back, then after 8 more getworks, another submitted, 2 more getworks, then a single accepted.  Now four New jobs....  Diff1.

It appears to be resetting.

I took off the heatsink, added some compound to the away side of the sheet, smoothed, reassembled.

I tried a factory reset with the cat5 cable removed.  Saw the flashing of the single LED multiple times which then stopped.  Shut it down.  Put the jumper back on the center pin.  Plugged in the cat5, restarted, then couldn't find the device on 192.168.1.254 but did find it on the earlier IP address it had been assigned before the "reset".

It shows up 51 seconds but it's been up 10 minutes.

There are two 120mm fans hitting the heatsink.

So, it would seem to be a resetting issue.  May I ask the most common cause of a resetting issue?  Power supply or routing?
