System Description 13
Power Supply
The power supply consists of the power supply bay and one power supply module. You can
purchase and install an optional second module and have a redundant, 1+1 system. Either way, the
supply provides 275-watts of power and is designed to minimize EMI. The supply operates within
the following voltage ranges and is rated as follows:
•
100-120 V
∼
at 50/60 Hertz (Hz); 5.0 A maximum
•
200-240 V
∼
at 50/60 Hz; 2.5 A maximum
The DC output voltages of the power supply are +3.3 V, +5 V, +12 V, -12 V, and +5 V standby.
The power supply features a 24-pin main power connector and a 10-pin power supply signal
connector.
System Cooling
The chassis includes two system fans for cooling and airflow. Both fans provide cooling for the
processor(s), hard drives, and add-in cards. The power supply contains its own built-in fan for
cooling. As shown in Figure 3, two 80mm fans are located in the middle of the chassis to pull
cooling air through the chassis.
Security
To help prevent unauthorized entry or use of the system, the chassis includes a mechanical lock on
the front bezel to prevent access to the system’s peripherals and control panel. The chassis also
includes an intrusion switch that can be monitored by server management software. When the top
cover is opened, the switch transmits a signal to the server board, where server management
software processes the signal. For example, the system can be programmed to respond to an
intrusion by powering down or by locking the keyboard.
