Note: When moving or relocating certain configurations of the system, the Bulk Power Regulators (BPRs) must be
removed from the top of the rack (front and rear) to ensure product stability. Specifically, removal of the BPR from the
front and rear is required in systems that have a single I/O drawer.

Acoustical Noise Emissions

Product Configuration
7040 Acoustical Doors
7040 Slimline Doors
Notes:
1. Noise levels cited are for a typical configuration (Bulk Power, CEC cage, battery option, media drawer, and two
I/O drawers).
2. The 0.6-B (6-dB) reduction in noise emission levels with the acoustical rear door corresponds to a factor of 4
reduction. That is, the noise level of a single frame with thin covers is about the same as the noise level of four
frames with acoustical covers.
3. L is the upper-limit A-weighted sound power level; LpAm is the mean A-weighted sound pressure level at the
WAd
1-meter bystander positions; 1 B = 10 dB.
4. All measurements made in conformance with ISO 7779 and declared in conformance with ISO 9296.
