I changed password and moved miners to hosting facility.

Now when I log into web interface of miners I get this error:

How do I fix this?

PS: Miners are still hashing, but I can't change settings.

Im now waiting for delivery without PSUs, can someone post a pic of PDU or generally inside of Desk showing how power cables are connected.
Im planning to run 1TH units with two PSUs 900W & 850W. But not sure if there's PDU inside or if power cables are connected directly to modules?
Any info would be helpful.

Some comments on the software:

The temperature display on the front panel shows the first temperature sensor - would be nicer if it showed the higher of the two.

The target and cutoff temperatures don't seem to be changeable so I can't test if they actually work. There's no fan control as far as I can tell (the fans just run at full speed I think) so I guess the target temperature doesn't do anything yet. That's no big deal. But would be nice to know if the cutoff works. I have a suspicion it isn't implemented yet - at least, I couldn't find any code in MinerOS either handling this or passing the temperatures through to cgminer. It would be nice to have a working thermal cutoff in place before warmer weather arrives.

Sometimes some of the AJAX URLs stop responding. I've had the module info disappear from the dashboard page - and also the temperatures and total speed. The odd thing is that a reboot doesn't fix this, but the dashboard does start working again eventually.

E please add overclocking How to.

Do I understand it right, that I have to change /mineros/boot.py?

Edit:
My miners were delivered yesterday, here is some gathered knowledge.

Delivered boxes were in good shape, miners are really heavy.

Ribbon cable was disconnected from module interface board (both miners) and module interface board was disconnected from 1-2 boards on opposite side from ribbon cable (5 module miner) even though small piece of foam was inserted between module interface board and cover.

Sometimes miner does not pick up IP address from DHCP server (on display is shown 0.0.0.0 frever), after power cycling it connects to the network.

Pool balancing in CGminer settings after restart of CGminer returns to Balance mode.

Power consumption of 5 module miner is around 1070W.

Overclocking is not worth it, power consumption rises a lot and errors too.

Run a Bitcoin node.

To quote the first poster on jgarzik's thread:

To paraphrase jgarzik (https://bitcointalksearch.org/topic/m.1496089),

Here is a general thread for owners of CoinCraft series miners (Desk and Rig)

For those waiting for deliveries or thinking about ordering, please see the Official and Unofficial CoinCraft Series threads:

Normal Boot Sequence Video
Soon...

Troubleshooting after Delivery
The fans should turn on about 5-20 seconds after you apply power. If they don't, power off and check to see if the fan cables have gotten tangled in the fan blades. Also check the fan connections close to the fans and at the controller board end.

If your miner powers on and runs through a normal boot sequence, but fails to start mining (and you've double-checked your network and cgminer configuration), check the connection between the controller board (sandwiched underneath the rPi) and the module interface board (the red board running across the top of the modules). The connection is a ribbon cable that can come unplugged at either end due to jostling from the power supply cords.

Reviews

E's capsule review: Thumbs-up with caveats. 1TH/s units so far have shipped with 240V-only power supplies. Securing internal cords, cables, and connectors before shipping would resolve most of my concerns. Some worries about power supply longevity due to negative pressure cooling.

Efficiency and Overclocking
Here are my measurements for a three module unit with 1000W Super Flower SF-1000P14XE, running on a 120V circuit (voltage at-wall about 119). All power measurements made through simultaneous V/A sampling with calibrated true RMS meters (Keithley 179A):
