Dell PowerEdge MX7000 Acoustical Baffle Specifications User Guide
Summary
Dell EMC PowerEdge MX7000 Acoustical Baffle technical white paper by Paul Waters and Amrita Maguire from the PowerEdge Product Group. Addresses noise challenges in 14th-generation modular rack systems where cooling demands generate more acoustical energy than traditional rack-mount servers. The MX7000 Acoustical Baffle is an optional snap-on add-on for the MX7000 rear that requires no tools for field installation. User feedback indicates the baffle improves sound quality to 'a kind of white nois

environments, the new Power Edge MX7000 offers an optional Acoustical Baffle.
Users have commented that the baffle improved sound quality “to a kind of white noise”.
Installation of the MX7000 Acoustical Baffle can be performed quickly in the field, no tools required.

The acoustical baffle is an optional, simple-to-install add-on that snaps to the rear of the MX7000 chassis directly behind the rear fans. When installed, the baffle improves the acoustical output of the rear fans and diffuses some of the airflow away from someone working behind the chassis. The acoustical baffle is specifically designed for noise-sensitive deployments that may require temporary or permanent noise mitigation. IT professionals surveyed on the performance of the baffle reported that it improved sound quality “to a kind of white noise”, and that it “removed shrill tones by muffling the higher frequencies”. Most importantly, when the baffle is deployed in conjunction with the Sound Cap profile in i DRAC, noise levels typically remain low enough to carry on a conversation within a meter of the chassis.

Frequently Asked Questions
How difficult is it to install the Acoustical Baffle?
Installation is simple and quick in the field, requiring no tools. It snaps onto the rear of the MX7000 chassis behind the fans.
Does the baffle only reduce noise or also improve sound quality?
It improves sound quality by muffling higher frequencies, which users have noted helps make the background operational noise resemble a kind of white noise.
Are there any systems I should not use this baffle on?
You shouldn't use it for systems where the CPU TDP is greater than 140W, or in environments warmer than 35°C, as performance may be impacted in these conditions.
Is this accessory designed or safe to use for cable management?
No, the baffle is not a cable management tool and cannot support the weight of cables. You must never affix or lay cables on it.
