Power Supplies

The chassis can be configured with one, two, or three 400-watt power supplies, each designed to
minimize EMI and RFI. Each supply operates within the following voltage ranges and is rated as
follows:
100-120 V at 50/60 Hertz (Hz); 7.6 A maximum
200-240 V at 50/60 Hz; 3.8 A maximum
The DC output voltages of each power supply are:
+3.3 V at 36 A max
+5 V at 24 A max (total combined output of +3.3 V and +5.5 V not to exceed 195 W)
+12 V at 18.0 A with 19.0 A <10ms peak
+24 V at 50mA
-12 V at 0.5 A
+5 V standby 1.5 A
Power is sourced through the power cable to the 20-pin main connectors on the baseboard. Remote
sensing signals are provided through the cable to the 14-pin auxiliary connector on the baseboard.

System Cooling

The minimum chassis configuration includes three fans for cooling and airflow. The chassis can
accept up to five more fans. The number of additional fans depends on your configuration: one
fan for each power supply (up to three) and two fans for cooling hard drives.
NOTE
The access cover must be on the system for proper cooling.
