We have 9 Rocket M5 connected to a WS-12-250-DC Switch, all Rocket emit a sound as if the power supply failed ... I can not express it in text, but it's like a bee inside the rocket.
This is in all the equipment, already we tried to replace several rocket by new units.
Can be Netonix problem? Im use 1.4.7rc4 firmware.
Any help, thank you

I do not see how.
What could be going on is ground current if your tower grounds are not bonded to your electrical service ground rods and the ground current is running through the Switch, Ethernet cables, and radios.
Ground current is BAD.
Other than that please post up a screen grab of your Stats Tab and Device/Status Tab
Here are some good posts on grounding:viewtopic.php?f=30&t=1816viewtopic.php?f=30&t=188viewtopic.php?f=30&t=1429viewtopic.php?f=17&t=1786&start=30#p13447https://community.ubnt.com/t5/airFiber/ ... rue#M31070

Everything looks good there?
As I said maybe you have a ground current issue?
Describe the site:
Type of tower?
Is the the tower grounded and how?
Equipment box location?
Where do you get AC power from?
Are the tower ground rods bonded to the electrical service ground rods?
