Bladecenter H 2880W Breakout Boards. Selling from stock, limited time discount

[dmwardjr]

I was up until 8:00am this morning [All nighter!] installing the new fan, setting up the rack, PDU's, PSU's with PCI-e cords and rigs.  I still have more rigs to bring over into the new closet [You might see them in the other closet in the background].  I'm waiting on a couple more 240 VOLT/30 AMP outlets to arrive from Amazon tomorrow so I can add another PDU.  Then I will be able to bring my router, switch and other rigs into the new closet.  I have to leave the door with grilles open at the moment to allow the 15 feet ethernet cords to reach from the switch to the rigs in the new closet.  I will be very happy to get those outlets in the mail so I can get that switch inside the closet to close the door with grilles.  I will clean up the wiring with zip ties when I get all of the rigs in the new closet.


Pictures of what I've done in the transition over from the old to the new closet thus far:



Don't be fooled... The fan is not held up by zip ties [lol].  The next picture shows the clips holding it in place.  The entire fan is resting inside the circle I cut in the wood with a jig saw.  The clips are holding the fan in place while it rests on the wood.  I found there was no need to screw a bolt through the black hanger into the joist above.  The fan rests perfectly on the wood while it is pushed through to the outside approximately 6 inches to where the handle rests against the wood.  So I decided to attach the handle to the wood to hold the fan in place.

The reason I have more wood to the left of the fan is to allow space to mount my power outlets, etc.  I will mount the outlets in place later.  I was tired last night!






The next two pictures show you how I hanged the IBM 2880W PSU's with tie wraps to keep them off of the SP20's.

Thanks very much!  Still a work in progress.

It's sucking the heat out to the outside.  That's the most important thing... Getting the heat out; rather than trying to overcome it with AC.  I will upgrade this fan from 7,800 CFM to 22,800 CFM when I add another 60 TH/s.

A little more has been added to it.  41.4 TH/s that is under clocked to 35.4 TH/s at the moment for better power efficiency.  All of the S3's have been upgraded to the latest firmware to under clock by varying the frequency and the voltage [All S3's at 193 MHz and 0625 volts for 380 GH/s to 400 GH/s each].

Those Corsair's will be replaced with 2880W PSU's once I've finished my taxes and made some solder connections on the breakout boards.

Thanks for the breakout boards!



These 2880's are loud!

This is the man who has it going on right here!  Very nice set up you have there, Sir!  Are you enjoying the Neptune's?  I know you are enjoying these 2880W's and the breakout boards.  The breakout boards really make things easier.

j4bberwock, do you have any more of these boards in stock?  HolyBitcoin doesn't have them listed as an available product.

I'm currently finishing the assembly of the first batch after some trouble with out of specs connectors.
For the US market, you can contact Finksy, he have them in stock.

Do you have reseller or supplier in Australia?

Do you have reseller or supplier in Australia?

No, but I can either ship them myself for now, or have them shipped from US.
I already had a few requests/buyers from Australia for my different boards, so, depending on the potential market size, someone who wants to resell any/all of my boards can contact me.

Hello, maybe you can tell where i can buy many of Astec AA23920L? And your boards for that will be next step =)

Thanks.

Depending on where you live, Ebay may work fine. You can use bladecenter H or 2880w (sometimes 2900w) as key words
in the US, it's not unusual to find the PSU for 50$ shipped.
In Europe, prices are closer to 80$

[J4bberwock]

Boards are now in stock, and I have enough components available to allow fast turn around even on 50+ orders.
I'm away for the next 8-10 days. For all new orders, next shipping day will be on the 4th of May.

So I bought a couple of break out boards a few months ago and it seem they are not working now? The fans on the psu wont spin , I thought the psus were bad ( 2880 IBM ones )
But I got two brand  new psus off eBay and its the same deal, first two green lights go on
Psu starts to get super hot BC fans wont activate

I've tried sp20s ants 🐜. Any ideas?

The PSU's can go bad but they are pretty stout. I had an on/off switch break off when I dropped one from 10 feet. I bent and jammed a paperclip in the remaining switch to short the pins to turn it back on again.

One of those green lights tells you the AC power is on, the other will tell you when DC power is there, and that will only happen if the power supply is good and the switch on the back of the board is flipped on.

There are two orange lights for a voltage error and a fan error, I have never seen any of these lights activate yet.  If both AC/DC power lights are on but fans are not spinning I would say the fans are dead somehow. There is a part number for just the fan replacement but the power supplies are already so inexpensive its probably the same cost just to get another power supply.

[Marvell1]

These are return psus right off eBay both of them can't be DOA can they?

You sure its not the adapter not working properly?

[LordPaco]

I have had about a 96% success rate in these used power supplies. I have yet to have one of these breakout boards go dead. Even the prototypes I received back in December are still ticking strong and have many hours on them now. The breakout board has nothing to do with the fans at all, that is all done inside the power supply.

So if you see one light with the power switch flipped to off, then when you switch it on you see two green lights, and still have no fan - it is most definitely the power supply.
