the new firmware fixed the subnet issue for me 
The 192.168.1.1 router issue? Yes. Before the update I had to edit cgminer.sh after every reboot, now I don't have to.

If you can measure the wattage at the wall, i would appreciate .
My meter is holding pretty steady at 1111w-1114w. It's not the kill-a-watt, it's pretty similar but made by Keedox.
Looks like mine is pulling 990W at the wall @110V on the 20AMP line, on the 15AMP line the PSU was shutting down every 2-3 minutes. After 30 minutes it's averaging 900GHs, so not a full 1TH. I will try the 1350W Platimax tomorrow to see if that makes a difference.
Awsome please report back.
if you have a voltmeter check the levels - you could have a bit of voltage drop in the thinner 15A wiring. 105V vs 110V could be enough to drop the PSU efficiency a bit
Well gentlemen (and ladies, perhaps??),
hope i'm not jinxing anything, so i'll say this with a hushed voice...
they're working......
All 3 are up and running.
Firmware updated to april 4 build.
DHCP in the 192.168.2.x subnet working.
max temp is about 60ºC in about 28ºC ambient temperature.
all 3 needed their boards to be re-seated, ribbon cable to lcd connected (both ends sometimes), loose pcie power cable to power supply, etc. All 3 power supplies are clearly used - lots of old dust. but all the boards appear brand new.
my "discarded" rates are sky-high, as is being discussed by others more knowledgable than I.
Thanks to everyone who took the time to share their experience and insights.

Here are the calcs.
1114W load @ 110V.
90.5% efficient @ 100% load @ 110V.
Internal load of 1008W.
And on 230V
92% efficient
Internal load of 1008W.
External power draw of 1095W.
PSU is specifically designed for 24/7 use @ 50C. Therefore there is a significant thermal safety factor on max load alone - even forgetting the usual one.
Tldr, its k.

Hmmm - gigavps' image says the PSU is rated at max 996W ... total max 1000W ...

I had a steady 9.5A on my 120v PDU
geez - if the PSU is actually ~85% efficient on 120V at high loads, then there must be upwards of 950W loaded on it
Which is fine. Most PSU components are rated for 200k hours upwards, at 100% load and 35-50C. You'd be surprised how stable proper PSUs can be.

How much does it use on your 240v PDU?

Also everyone, whats your percentage accepted shares by your pool?
Please list the pool and the difficulty setting as well.
Thanks
Unfortunately that number appears to not be very useful at the moment.Please list the pool and the difficulty setting as well.
Thanks
The majority of rejected shares seems to be caused by the bitmain driver sending shares that it shouldn't send.
Once I can get my hands on the source code (which really should have been available already) I can sort out what's been messed up
+1 i wish all the miner manufacture let core developers of cgminer work on the software b4 shipping to sort out the bugs.

anyone successfully using a subnet other than 192.168.1.x? how about DHCP?
i'd rather not have to hack the files in the firmware to change subnet. Would like to rely on DHCP in the 192.168.2.x subnet.
Anyone doing so successfully?

Yeah, just update the firmware and you'll won't need to edit any files. Even if you chose the edit files route, it's not really "hacking" and they are overwritten at reboot so you aren't actually risking anything. The firmware update is the best option, though. DHCP works fine, I have mine setup on the 10.x.x.x subnet
The firmware is here:
https://github.com/AntMiner/AntGen1/tree/master/firmware_S2
Mine showed up today too, and thought I should chime in with my experience.
Thanks to previous posters, I popped the case as soon as it was unboxed. Appeared undamaged, but did need to reseat the CPU board and reattach the display panel cable which had been disconnected. Plugged in the ethernet (had already switched my router's subnet to 192.168.1.x), powered it up, and happily it started hashing away after a minute. Connected to it from my browser, changed the miner settings to my pool, and it's still golden.
It's been running for 2hrs now at 1006 GH/s, and I feel lucky given the grief others have been reporting.
