Yep that should be possible to do. However I hear that the dev crew are labouring to come up with with a workaround for the control board issues.
Also in regards to the avalon unit coming back online from a power outage, sometimes that does not happen. Rarely what could happen is the unit will be left in a zombie like state because the control board did not initialize properly. For me this happened once when there was a brownout.
would the control board respond to a ping in that situation from this device? http://dataprobe.com/iboot-g2.php
Bear in mind that router board (which runs the cgminer software and management front end) is NOT the control board. What I mean by the control board is the Spart6 FPGA board that takes the instructions from the cgminer software running on the router board and coverts that to work batches for the ASICS. The control board is the one with all the "IDE like" cables running out of it and to the individual hashing modules. The control board does not respond to ping requests because it is not accessible via any network protocols as it's attached to the router board via USB. The router board responds to ping request and I'd imagine it would also respond to ping request even if the mining software is not running or in some sort of locked up or crashed state. If the router's OS was completely down or broken then yes it would not respond to ping requests. The power control devices - dataprobe - are of limited use in this scenario. They are still useful for when you want to quickly power cycle the machine for whatever reason.
Edit: Ooops..seems there is a iBoot-G2+ which allows you to control up to 3 power outlets. Neat!
Yep, it is a neat device but you're stuck having to constantly ssh in to try and catch the rare zombie like condition.
What other solutions are there assuming they're kept off site?
since nobody seems to have the answer to this question, i'll just ask another.
the iBoot has a Windows software protocol called Heartbeat which can be installed on a computer which will send "heartbeat" signals to the iBoot periodically to indicate its functioning. this is the reverse direction of the ping function originating from the iBoot.
i wonder if it would be possible to write a linux version of this and install it into openwrt and have it monitor the control board and make it fail to send "heartbeats" to iBoot in the case of a control board freeze which would then trigger a reboot?
I am not sure if this has been answered however.
Is there some way to increase the fan speed on the units?

but seasonic are (too?) large
I highly recommend Seasonic PSU's. I've used them in all my computers and they are of awesome quality and very efficient. Check out their X series.

well, there's definitely a difference of opinion around here in regards to UPS.
both galambo and Death & Taxes have gone on record against UPS with these things. you'd have to hunt about the details though in other threads.

Well I think the main problem with putting a UPS behind these things is that they're absolute power consumption monsters and it takes one beefy ass UPS to feed them for a reasonable amount of time - enough to last the average blackout.
I was thinking of getting some 1440 or 1500VA units. Haven't pulled the trigger yet though. Where did galambo and Death & Taxes discuss this?
here's D&T's response when i asked him this in a pm:
"Getting a UPS capable of handling that kind of wattage is going to be expensive plus all UPS add load and inefficiency. If it were me I wouldn't be considering a UPS. "
Yep I agree completely with him. The only reason I guess I even considered getting a few USPs is paranoia. Maybe hosting these at a data center is the best solution (if you have multiple as that would justify the potentially high monthly cost).

In my instance the zombie state was caused by a power outage - essentially a brownout. Power cycling the machine fixed that issue. I haven't ran into the zombie state being caused by firmware issues. However I am now running 4-10 which supposedly fixed this issue. So far I'm really happy with 4-10. I'm keeping a close eye on the HW errors and rejected shares to see if it has improved relative to previous firmware, but just by a quick glance (without doing any calculations) it seem that it has.
Also in regards to the avalon unit coming back online from a power outage, sometimes that does not happen. Rarely what could happen is the unit will be left in a zombie like state because the control board did not initialize properly. For me this happened once when there was a brownout.
did you find a solution to fix when it gets in zombie like state? just reboot again?
I've had this problem a few times and had lots of trouble getting it to come back. Restarting cgminer seemed to help, but sometimes I've had to restart it several times before it comes back to life. The 4/10 NEXT firmware seems to be better about the zombie state.

think depends on where you live.

True, but more than often it's not about just the power going out but the quality of the power coming in. You can get some pretty shitty current sometimes, but a good power supply should compensate for this most of the times. As always, don't cheap out on the PSU (if you intend to replace the stock units).

Definitely have to have a UPS connected to protect the unit from surges and spikes. DO NOT trust a power strip. They will not protect your Avalon. A UPS will absorb surges and compensate to spikes...so your Avalon will constantly get clean unadulterated power.

Careful there with UPSs that do not give sine wave output. APFC power supplies will trip their power protection circuitry and not work when fed with approximate sine wave (sawtooth) output.
I recommend the SmartUPS series or something that puts out pure sine wave.

Oh, and for the record UPSs do NOT have stronger surge absorption capabilities than a good surge protector (varies of course on the quality of your surge protector). Hook the UPS up to a strong surge suppressor. Do NOT hook up a surge protector to a UPS.
