RJ45+ control module hum/whine

[EndlessSummerAZ]

Turned off my RJ45+ overnight. Went to turn it on this morning and the control module was making an unusual, loud humming/whining noise. Turned it off and back on and it still made the noise. Tried off/on once more and the humming has seemed to subside. Anyone experience anything like this before? Debating reaching out to DSP as the unit is less than a year old. Video attached is of unit making noise starting up.

Mine does that every once in a while. I bump it with the palm of my hand and it goes away.

Could be the transformer inside. They can make a whining/humming noise when they power up. If it’s possible to open up the unit and look inside, I would ensure that everything is bolted down properly and then look to make sure nothing is corroded or burned.

Also check the internal cooling fan and clean any dirt/dust off the fan blades and surrounding area.

One even had loose screws so the housing was vibrating on the post.
