1. Power consumption and heat output vary depending on the number and type of optional features
installed and the power-management optional features in use.
2. 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. Actual sound-pressure levels in a given location might exceed the
average values stated because of room reflections and other nearby noise sources. The noise
emission level stated in the declared (upper limit) sound-power level, in bels, for a random sample
of system.
Hot-swap fans:
Your server supports both single-rotor and dual-rotor fans.
• One microprocessor: four single-rotor or dual-rotor hot-swap fans
• Two microprocessors: six single-rotor or dual-rotor hot-swap fans
Notes:
• Do not mix single-rotor and dual-rotor fans.
• On the integrated management module (IMM) Web interface or the ipmitool program interface,
the value of Fan xB Tach is only available for dual-rotor fans installed in your server. x represents
the fan ID.
Power supply:
• Up to two hot-swap power supplies for redundancy support
– 550-watt ac 80 PLUS Platinum
– 750-watt ac 80 PLUS Platinum
– 750-watt ac 80 PLUS Titanium
– 900-watt ac 80 PLUS Platinum
– 900-watt dc
– 1300-watt ac 80 PLUS Titanium
– 1500-watt ac 80 PLUS Platinum
Notes:
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/
resources/ powerconfig.html.
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,
