Does your cisco asa 5512 make noise?

Question

Cisco

Good time!
Colleagues,
I bought a Cisco asa 5512, when turned on, the cooling fans work fine, the noise is at the level of 30-34 dB. At the final loading of the piece of iron, the fans start to work at maximum, the noise is already at the level of 64 dB. In the server temperature 17.6, there is no load, the piece of iron works fine.
Another bug that I do not understand is that the lights on the front (plastic) panel do not light up, the indicators on the back are dim. Dismantled, everything is assembled normally, all cables are connected, cooling of the stone is present and cools.
Who thread had a similar situation?

Answer 1

There was a case: [SOLVED] ASA 5512. Temperature sensor .
When the fans are noisy, look at the temperature:
It was all about the detached contact of the loop. I removed the cover, near the processor slot there is a cable mount from the front panel, and incoming air sensors are apparently installed there. He took it out, put it back in place and everything worked as it should: the temperature is normal, it does not make noise.
