Avalon A1041 Review

[cottora]

In regards to the PSU discussion...Curios, we have about 800 841 that we are starting to phase out and we are thinking about buying some used 1041s.  We have good 841 PSUs in the boneyard, is it possible to use two 841 PSU to power one 1041 (just thinking about cost savings if we get a PSU failure on a 1041).

Thanks

Low power mode in the A1047 is now only doing 25 TH. Anyone noticed it? Has this issue been fixed?

From the A10xx on up all Canaan miners use a built-in PSU and CANNOT use an external one.
Why? Simple - the reason is to squeeze every bit of efficiency they can get. As Bitmain has done the chips on the hash boards are directly powered by the PSU vs having a final high current regulator on each board. The PSU is programmable via the controller and directly sets voltage to the ASIC strings. Losing the secondary regulators boosts eff by several %.

Thank you!

Curios, what are the review of the 1041 now that we are a year into the original post?

I like them. Only thing against the 1041 is that Canaan so far has not released an update for it to use 3 pools & have More Options entry box like they did for the 1047 on up.

Very occasionally the 10xx series may have an issue connecting to some routers, not sure why but a reboot of the router seems to take care of it.

I got mine working with 3 pools.

did you use the inspect page option

Has anyone messed around with the privileged API for the A10 series?

[cottora]

Does anyone have trouble with the idle/shutdown command?  We have a mix of about 60 A10s and they are sporadic when we send an idle command.  Some idle as intended, some show 150c temps, idle down, and then reboot.

Code:

2.8. Shut down HASH power
Note	Shut down the HASH power supply to make the miner enter the low power state. To return to the working state, use the reboot API command.

Format	ascset|0,hashpower,0

I get an error when trying to enter privilege mode (and any privilege commands).

I suspect there may be differences between different firmware versions. I attempted to use the API to set the pool on a few 1066s and ended up with two miners that are hashing nowhere. Been waiting 2 days for my host to do a factory reset to get them back up... The web UI freezes up after the login screen.

Some of the commands listed in the API returned an unknown command error. But the reboot, idle, and pool commands didn't return any errors.

[cottora]

I am now also having issues setting the pool.  Below is the error I get when sending the exact command that is in the manual

Code:

echo -n "ascset|0,setpool,root,root,stratum+tcp://btc.ss.poolin.com:443,cctrix.001,123" | socat -t 30 stdio tcp:192.168.88.187:4028,shut-none && echo

STATUS=E,When=3261,Code=120,Msg=ASC 0 set failed: we need 6 arguments\, your input is 2 arguments.,Description=cgminer 4.11.1|

[smracer]

Here is mine - it works perfectly

Code:

echo -n 'ascset|0,setpool,root,root,stratum+tcp://btc.ss.poolin.com:443,btcpig.001,123' | socat -t 10 stdio tcp:192.168.2.'$count':4028,shut-none && echo

The only difference is the quotes?

[cottora]

Thanks for the reply!  What version FW are you using?  I get the same error.

[smracer]

Newest firmware

[cottora]

Canaan clarified the changes in the command. With the newer FW that allows for multiple pools, you must specify the pool number in the command. For example, to set pool #2 you put "2" after the miner password:

Code:

echo -n "ascset|0,setpool,root,root,2,stratum+tcp://btc.ss.poolin.com:443,cctrix.001,123" | socat -t 300 stdio tcp:192.168.1.174:4028,shut-none && echo

In order to set all three pools, a total of three commands must be executed, where the number will be 0, 1, and 2 to set each of the pools. A reboot is needed after pools are set.

Is there a C19 to nema 5-20 cord for an Avalon 1047?

Edit: All my search results are for 120V cords. I don't see any results for 240V. Stupid electricians anyway.

[NotFuzzyWarm]

Is there a C19 to nema 5-20p cord for an Avalon 1047?

No because a NEMA 5-20 is for use with 110VAC @ up to 20A - not 220V. The A1047 PSU requires a minimum of 208VAC input and all (NEMA rated) 208-250VAC connectors are NEMA 6-xx.

Okay. Is there a recommended outlet I can replace the NEMA 5-20 the electricians installed? Is there a type B outlet for 220V?

[NotFuzzyWarm]

Sure. These for example Your local hardware store, Home Depot, etc. should have them.

Key point is you need to have 208-240v ran to it. Is the circuit already 208-240VAC? And if it is, why the hell did the electrician put in a NEMA 5-xx socket rated for only 110V?

That is a blatant code violation... Not so much from a direct risk of fire from the higher voltage but rather because it allows someone to plug devices made for only 110v into it which would have very bad consequences.
