System Chassis

Power Supplies

Two 400 watt auto-voltage-sensing power supplies provide system power. Each operates at 115 or 230 Vac at an operating frequency of 50/60 Hz. Both supplies are designed to operate together during system operation. Both power supplies comply with existing emissions standards and provide sufficient power for a fully loaded system configuration. An optional third power supply can be added to the system as a backup unit.

System Cooling

The chassis houses eight fans for cooling and airflow.

Note: To maintain proper system cooling and air flow, the chassis access cover must be installed whenever the system is running.
