stated in the declared (upper limit) sound-power level, in bels, for a
random sample of system.
Hot-swap fans:
v One microprocessor: 4 dual-motor hot-swap fans
v Two microprocessors: 6 dual-motor hot-swap fans
Power supply:
v 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
Note:
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 IBM Power Configurator utility to determine current
system power consumption. For more information and to download the
