22 asicminer blades

[crudpuppy]

Got them all powers some fans blowing on them running them all through slush's proxy on a Linux box and hooked to btcguild pool.
20 are in 2 backplanes with the hp power supply 2 more on a separate PSU
Now the problems
1) NONE of them are working at full efficiency 80s% on them all
so heat? power what? Just too many through the proxy?

2) 1 of the has stopped connecting to network.  Gets power the little green light flashes but no network?!!?!
no ideas here other then bad board.

You got enough wattage there?

Running these http://www.amazon.com/HP-403781-001-DL380-1000W-Supply/dp/B001U0EM1W/  which is what people said they run with the backplanes 1 per backplane  This is the recommended PSU for the backplane as far as I know.

Try running BFGMiner and it's getwork proxy.  It's way more efficient than slush's proxy.

I may have gotten this working now well sept the on blade not getting on network
I moved blades and proxy box to own router hooked to main router so that all that traffic is off to itself
I also changed proxy box to dual nic setup on said network segment
Blades are now running 97+ efficiency again!

Basically way too much traffic for my main network with kids streaming movies etc from youtube/Netflix/hulu plus widening the proxy box's network path.

Ok so I got my efficiency worked out.   
Anyone have any idea on the blade that blinks when powered but never goes online?  the lil green led blinks when first powered like others but never shows status lights on network port  it is 1 of 10 in one of 2 backplane setups that are the same so not a powering issue as other backplane with exact same PSU has all 10 powered no problem.

You might check solder connections of the ethernet port. I remember someone mentioned several weeks ago having received one with a badly attached network jack.

Preface I'm no component level guy. 
Are there separate paths for the 4 pin connector power then the slot power?  Moved it out of the backplane and hooked to a PSU separate and it seems to do ok now...leaving it like this I guess just more curious why that worked.  Had moved it out more or less to play and check power to places with a multimeter but it worked...lol

looks like it was a bad connection between the backplane and the blade.
