Notes:

1.LWAd is the declared (upper limit) sound power level for a random sample of machines. (1B = 10dB)

2.LpAm 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)

4.7028 Model 6C4 levels apply to the following hardware configurations: 2 way 1 gigahertz processor, 2 disk drives, 2048 GB of RAM, redundant power supply (Two 645 watt power supplys, 2 processor fans)

5.All measurements made in conformance with ISO 7779 and declared in conformance with ISO 9296.
