Is there a way to disable the beeping sound when the miner loses internet connectivity?

a little crazy-glue in the hole will quiet that piezo right up!

Where is it located?   Easy to do this?

[VRobb]

Yeah, it's easy.  Look for something like this: http://shallowsky.com/arduino/class/buzzer.jpg on the control board.  Small drop of glue in the hole and it's nice and quiet...  well, at least the beeper will be!

Way easier than I thought.   Thank you

Any way to do it by software? (remotely)

I think the idea is that you have access to your property?

Review beep = false

Hmm that looks like the soft way to do it. I will try it out.
Thanks!

I just purchased two of these.  I like that they run on 110v and my house uses electric heat.  My wife lets me use them since they are quiet. 

Question on power.  I understand the default frequency is 600 and powered via a 1,000 watt PSU.  However, when plugged into a Kill-A-Watt, in order to get it under 1,000 watts, I need to set the frequency to 450 which keeps it around 900 watts (for some safety). 

How can the default be 600 when it pulls in excesses of 1,000 watts when using the default frequency?

[philipma1957]

well let me ask you.  does your miner have two boards or three boards.

when your kwatt meter runs are 900 watts are you getting 3.6 th  hash rate.

or do you get 3.0 th hashtate..?

your numbers seem wrong.

My S7-LN has 2 boards.  PSU is a Cougar GX 1,000 Gold.  The PSU itself pulls just shy of 100 watts.

Frequency is currently set at 500 - 2.2 TH/s - Pulling 990 watts.  So the miner itself is using 890 and the PSU 100.

When I turn the frequency up to 600 I get - 2.8 TH/s - Pulling 1,200 watts.  So the miner itself is using 1,100 and the PSU 100.

I am getting very similar results on my other S7-LN.  I thought it may have been the PSU so I put an old APW3++ PSU on this unit.  Although the PSU uses more wattage, the miner is pulling similar power.
