     Tested for 180 days!!!!

     This seems like a new regular thing.  I can't help but feel that some of these companies treat individual customers (and small business customers) like dealers selling to drug addicts.  "you'll get it when I say you get it"  and yes, include the 'stomped down and cut' metaphors for lost time and profits.

Can you doublecheck that the connections are ok and can you measure if there is a 12V output from the power supply? (you need a multimeter for this)

All connection are good. So, the power supply comes with 10 ports but the miner only have 6 ports, the question is does the port has to plug in in orders? ( i don't know which one to which).
I will get measure it tomorrow when i get one,

Also the PSU input is 180/260V AC, so i have to use 220v right?

As long as those six ports in the miner are powered, you are ok.
There is no specific connection order for the cables.
And you don't need to worry about spare pci-e power cables.

Yes.

I just received my order today, thankfully it's on time shipment.
I tried to plug it in, only power supply power up (i use power supply that comes with miner), miner itself no light no fan. Am i missing something to power up the miner?
Anyone has this issues? Am i missing something?
Thanks

More simply - make sure that you are using 220V or a voltage that matches the input requirement for the PSU. It sounds like you may be trying to power the PSU with 110V. Hyperbit support was supposed to ask you which voltage you preferred prior to shipping.

I tried 110v, i tried 220v, neither works
Would it be some losing cable inside of miner?
When you power up, the miner automatically turn on or you have to hit reset button?

ROFL the price of this asic is just stupid $2500 when bitmains l3+ is 1593 right now, not worth it to buy this bw-l21 asic

[omgcoins]

Damn, turn out my transformer was not working properly on 220v, i used multi reader to verify this, get new one at local shop and working great.
Another question is, since nicehash was hacked. What is best alternative one for ltc pool?
Thanks guys for the help.

I used to mine at Nicehash.

I'm now mining at Prohashing.com

to tell you the truth...I'm not sure if www.prohashing.com now is doing any better than www.litecoinpool.org

at 101% payout and no fees.

using this calc (which has 101% built-in) www.litecoinpool.org/calc

With bitconnect no longer a POW coin and everyone piling into LTC...it may be a draw!

I used to make 15% to 20% more a day on prohashing..but them days seem to be gone ....

You have to wait a bit for Bitmain, but you're right, the L21s are WAY overpriced for what you get IMHO.  Hyperbit lost our shipment (along with others) and was a month late. So, ordering the high priced L21, really wasn't worth it compared to Bitmain.  At Bitmain recently, we've had orders verified in 15 minutes, shipped before schedule and next day customer service.  At Hyperbit, we were refused compensation (although promised) and/or shipping refund for the month late order unless we ordered again! Lol.

Consider BW for your L21s

I have had a recent order arrive 1 month earlier than expected from antminer!

Great, isn't it? Hyperbit's view that Bitmain's service is awful seems to be a difficult argument to support, especially when they cannot provide even location information for shipments.

I think eventually there will be some competition.. just not today..

The best thing about the L21s is that they run very cool.  There's no adjustment for the fans though.  One speed only and that's about 7,000 RPM.

Is the fan loud?  The l3+ fan is very quiet..

Yeah it is all changed now that LTC price went up big time.

I might look at my strategy again and go mining LTC.

again..the only way to really test this is take an L3+ on each and compare....but too lazy.....

may have to re-think this as well...still on PH

so if it is oranges and oranges between litecoinpool and prohashing I will likely stay with prohashing...my bet since sept 2017 was ALL

my miners x11 / scrypt-pow all paid out 100% in LTC....damn..I nailed that

what freaks me out about LTC proportionally and historically LTC price to BTC price it could go over 1,000 usd per LTC and still not

break that framework arrangement at 17k btc!

befuddled as usual on what the hell is going on (normal operating procedure last 4 years...you'd think I'd get used to this and adapt!.

I did have a very good experience with the support staff at Hyperbit.  Very helpful and responded via personal email in less than one day.  In running the Bitmain and Hyperbit products side by side, I personally like the L3+ better.  The IP report button, crypto payments and rapid order confirmations, miner interface and availability of online support materials are all big advantages to us.  L-21s are good miners, just somewhat overpriced, led by someone who doesn't understand customer service and lacking some of the comfortable features that Bitmain has.
