Acoustical Noise Emissions; Environmental Specifications - IBM pSeries 690 Service Manual

Acoustical Noise Emissions

Product Configuration
7040 Acoustical Doors
7040 Slimline Doors
Notes:
1. Noise levels cited are for a typical configuration (A-Frame: 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 A-Frame with thin covers is about the same as the noise level of
four A-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.

Notes:
1. Storage and shipping specifications are valid for a maximum duration of two weeks each.
2. The upper limit of the dry bulb temperature must be derated 1 degree C per 189 m (619 ft.) above 1295 m (4250
ft.). Maximum altitude for 1.1 GHz modules is 3048 m (10,000 ft.) and for 1.3 GHz modules is 2134 m (7000 ft)
