Notes:
1. These levels were measured in controlled acoustical environments according to
procedures specified by ISO 7779 and are reported in accordance with ISO

2. The options supported in this server vary in function, power consumption, and
required cooling. Any increase in cooling required by these options will increase
the fan speed and generated sound level. The actual sound pressure levels
measured in your installation depend upon a variety of factors, including: the
number of racks in the installation; the size, materials, and configuration of the
room; the noise levels of other equipment; the room ambient temperature and
barometric pressure; and the location of employees in relation to the equipment.
