Acoustical Noise Emissions - IBM pSeries 630 6C4 Service Manual

Acoustical Noise Emissions

The equivalent continuous A-weighted sound pressure level at workstations (emission sound pressure
level at the 1-meter bystander positions) does not exceed 70 dB(A).
Der Geräuschpegel der Einheit ist kleiner oder gleich 70 db(A).

Notes:
LWAd
1. is the declared (upper limit) sound power level for a random sample of machines. (1B = 10dB)
LpAm
2. is the mean value of the A-weighted sound pressure level at the 1-meter bystander positions for a random
sample of machines.
3. 7028 Model 6E4 levels apply to the following system configurations: 2 way 1 gigahertz processor, 2 disk drives,
2048 GB of RAM, non-redundant power supply (One power supply, 1 processor fan).
