Nexus 9500 Noise Level

[Akilliez]

Good Day,

Can anyone advise on the levels of noise generated by the "Cisco Nexus 9500 Series Switch Chassis" ?

We currently have the Cisco Nexus 9500 series model (N9K-C9508: 8-Slot Chassis). Additionally, it is equipped with 3 fan trays (N9K-C9508-FAN).

I couldn't find neither the datasheets nor any documentation associated with the fan trays or its' associated levels of noise generated (A-Weighting / dBA).

Any help would be appreciated.

Thank you kindly,

Engineer A. Fairouz

If its like most other Nexus 9K platforms, im going to say loud...its a DC switch after all.

Agreed, we have 2 of them running at half capacity in our data center.

Renovations are being made on the room & I would like to take into account the noise generated for a better insulation grading of the rooms' interior.

For some reason, no data has been documented by cisco for these fan trays.

Hi @Akilliez 

There is no public info about the N9500's fan acoustics. You have two options to move forward: 

1. Send an email to documentation team (you have a feedback link on any cisco page).

2. Look at other Nexus 9000 platforms and see what is the noise level on those ones, and add few more dBs. For example:

https://www.cisco.com/c/en/us/products/collateral/switches/nexus-9000-series-switches/nexus-9300-gx-series-switches-ds.html

The N9K-C9364C-GX has:

●  77.3 dBA at 50% fan speed, 88.6 dBA at 70% fan speed, and 95.8 dBA at 100% fan speed

Hope it helps,

Sergiu
