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.
