SUMMARY

For highly-sensitive noise

environments, the new

PowerEdge 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.

Modular systems can be loud: The power, density, scalability and dynamic

range of rack-mounted modular systems (such as PowerEdge blade enclosures

and PowerEdge FX2) requires a powerful cooling capability that can generate

more acoustical energy than a traditional rack-mount server. Customers that

choose the scalability and flexibility of a modular platform often sacrifice noise

sensitivity in the process and are left with few choices when it comes to

mitigating the increased noise associated with these products. In the 14th-

generation of PowerEdge servers, Dell EMC has embraced this acoustical

challenge and worked with a jury of IT professionals to develop several

solutions for customers to reduce the noise impact of modular systems One of

these solutions is the MX7000 Acoustical Baffle.

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 iDRAC, noise levels typically remain low enough to

carry on a conversation within a meter of the chassis.

MX7000 Acoustical Baffle installation instructions Installation of the MX7000 Acoustical Baffle is simple and straightforward: 1. Access the rear of an MX7000 chassis. 2. Align the acoustical baffle with arms facing (inwards) toward the rear of the chassis and optical window on the bottom. 3. Locate the cut outs on each side of the rear of the chassis. 4. Push the baffle until the tabs engage onto the chassis. Image 2: MX7000 Acoustical Baffle installed at the rear of MX7000 chassis.
