1. Power supplies and redundant power supplies in the server must be with the same power rating,
wattage or level.
2. You may use the Power Configurator utility to determine current system power consumption. For
more information and to download the utility, go to http://www.ibm.com/ systems/bladecenter/

Acoustical noise emissions:
• Sound power, idling: 6.4 bels maximum
• Sound power, operating: 6.6 bels maximum
Notes:
1. The noise emission level stated is the declared (upper limit) sound power level, in bels, for a random
sample of machines. All measurements are made in accordance with ISO 7779 and reported in
conformance with ISO 9296.
2. The PCIe options supported in this system vary greatly in function, power draw, and required
cooling. Any increase in cooling required by these options will result in increased fan speed and
produced sound power 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 from other equipment; the room ambient
temperature and pressure, and employees' location in relation to the equipment.
