Netonix DC Issues

Hi Guys,
We've had some issues with the DC switches, the first issues were our own fault by plugging devices into the port when POE was still enabled.
Will this ever not be an issue? We haven't had this issue with any other POE switches.
The latest fault is a switch has been taken to site with the latest firmware on, device plugged in POE turned on, device powers up but no data.
Any idea?
Thanks

This should not be an issue, I have plugged POE loads into our switches thousands of times for testing. It is just a better practice not to do this in case you have shorted/bad cabling//device. Our switches come with a diagnostic that checks for bad cabling before applying POE power, which is the best way to do things.
The latest fault is a switch has been taken to site with the latest firmware on, device plugged in POE turned on, device powers up but no data.
Which model switch? Someone will respond later today to help you out.

Thanks Dave.
We had an issue today with a device which we plugged into a Netonix (24VH) and the port started smoking!
This port was powering a Mikrotik CCR1009-PC.
What have we done wrong?
Thanks

Because that device is not designed to get power on all 4 pairs.
Also do NOT select 24VH to power a 24V device, it will fry the device and the port.
24VH supplies power on all 4 pair which is needed for long cable runs (over 200 feet) on airFIBER X units but will damage normal 24V Rockets, Nanostations, and similar devices.
48VH supplies power on all 4 pair which is needed to power airFIBER 24 and airFIBER 5 units but will damage devices that only want power on pairs 3 & 4 such as Titanium Rockets or IP Phones and camera.
48VH is also used if powering a WS-6-MIN switch, MIMOSA B5, B5C, and other high power devices from many manufacturers. Always take time to verify a device polarity pin out and voltage requirements before using 48VH.
The only devices on the market to my knowledge that are designed to use 24VH are Ignite MetroLink and AFX radios but AFX radios prefer 48VH.
Did you not see the big warning POP up on the screen when you selected 24VH
You fried that device and damaged your switch.

From what I am reading the device supports an input voltage range of 14 V - 57 V with a Max Power consumption of 34W.
So with that in mind I would have used 48V not 24VH as I do not think that device is designed to accept power on all 4 pair.
Our 48V POE option delivers power on 2 pair at .75A or 36 watts so this is what I would have used.
Why did you chose to use 24VH for this and ignore the POPUP WARNING when you selected 24VH?
You most likely fried that unit and damaged your switch.
