You can log in with ssh and issue the halt command but other than that, most of the system is read-only so you can just hit the off button (as long as you don't have any pending change config / updates happening)

So far, I have not seen a shutdown button on the interface

is there any accepted shutdown procedure for the avalons or is it just hit the off button?

when are we going to be able to order 4th modules for batch 2 units?

All I can say is, how the heck you get a no_matching_work stat of 0...thats crazy! , ever avy screenshot Ive seen has a slight number above 0...

make sure your pc is on the same subnet as router.

demkd ,
I use BFGminer. cgminer don`t work with my avalon no one fpga and avalon in my system don`t work with cgminer. only bfgminer working. where I can see logs?

i hope you stop by Santorini.  just got back from a one week vacation there.  absolutely stunning.

Yes.

Good PSU
Then check cgminer api log, may be you have defective module.

I never do it by myself, but someone managed to reset this router successfully https://bitcointalksearch.org/topic/m.2673018

is tnat one?
ok, I have Corsair AX 1200 power souply. if I run this as external psu, is good?
I`m trying to reset but still nothing. ping coming, but I can`t conect to tp-link. may be i do something wrong.

Move out PSU from case.
I run my avalon with external PSU at 336 with 750 stock PSU (Enermax ENM750EWT-S RG) and it never restarts.
Tested @354 but noise level unacceptable, 750w PSU easily handle moderately overclocked units.
if problem still occurs than check you "cgminer api log"
It must be something like that (my unit @336 2 days w/o restart):
   [no_matching_work] => 0
   [match_work_count1] => 20069
   [match_work_count2] => 20320
   [match_work_count3] => 20197
   [match_work_count4] => 19944
   [match_work_count5] => 20103
   [match_work_count6] => 19962
   [match_work_count7] => 19976
   [match_work_count8] => 20163
   [match_work_count9] => 20064
   [match_work_count10] => 19961
   [match_work_count11] => 20056
   [match_work_count12] => 20235
   [match_work_count13] => 20173
   [match_work_count14] => 20481
   [match_work_count15] => 20215
   [match_work_count16] => 20042
   [match_work_count17] => 20044
   [match_work_count18] => 19992
   [match_work_count19] => 20040
   [match_work_count20] => 20398
   [match_work_count21] => 19627
   [match_work_count22] => 19978
   [match_work_count23] => 20354
   [match_work_count24] => 20186
All counters have almost same values. (~5% diffs) if not you have defective modules or some module overheated (usually second module w/o temp sensor ).

And you can try to reset your router, may be it's not dead.

There was a bug on BTCGuild yesterday. My 3 units also showed 350GH/S at the peak.
I'd post the picture, but I'm lazy.

I rechecked the schematics, I doubt it's got something to do with voltage mod, since the voltage regulator is a fixed one.
 That leaves coding trickery somewhere, unless I have grossly misunderstood something somewhere.

Batch 2 autoclock results:

ambient 80 - 85 F, 340 - 344MHz
ambient 75 - 80F, 348 - 353MHz

Have a nice holiday CON!

Something to share:
My batch 1 unit makes 83+GH steady autoclock reaching 355 Mhz stable err <2%
My batch 2 unit makes 80+ steady autoclock reaching 343  Mhz stable  err <2%

I have tried batch 2 unit clackoed at 350 auto-clock disabled - same performance  80+ with err about 5%

I am sure it is due to HW itslef. I am wondering what may be different. I will play with FPGA USB plugs(jumpers) when i have time

Can anyone share batch 2 results - auto clock ?

 

Just Greece from here on Net access is not so great so far where I am...

If you don't care about killing the fans then what you want is to set the fanspeed high, not set the target temperature low because if it can't keep the temperature low it will stop the avalon from clocking higher. Remove the avalon-temp argument and add --avalon-fan 80 to keep it at 80%. I don't think there's much advantage to going above 80% fanspeed due to it reversing the flow of the third fan.

just kill cgmiiner in the process tab,(if you see anything about max children, kill it also) kill it 2 times and then goto startup and then RESTART cgminer

So if I have inside  750W? there is no reason to change? a model is  unknown ... something in Chinese written on it.
 is stable at 300MHz, 325 goes to idle mode and orange light blinking. the temperature is not more than 48 degrees. it is the power supply or something else? I connected directly to PC because my TP-link internal router not working

I can recommend Corsair AX860i platinum. Not expensive.
But If you want best available PSU than get Seasonic 860 platinum.
If you remove stock PSU from the case (to prevent overheating) than any 750W PSU is good. (at 354 clock 3 module avalon drain only 630w from PSU (735-740w from wall for gold rated PSU))

I hope you upgraded the PSU before doing this on units you plan on selling
