System Specifications
Environmental Specifications
PCI/Mass Storage Section Cooling
Six (6) 92mm fans located between the Mass Storage Devices and the PCI Card Cage provide airflow through
these devices. The PCI fans are powered off of housekeeping power and + run at full speed at all times. The
air is pulled through the mass storage devices and pushed through the PCI Card Cage. Perforation is
provided between the PCI bulkheads to allow adequate exhaust ventilation and to help reduce the localized
airflow dead spots that typically occur at the faceplate tail of each PCI card.
Standby Cooling
Several components within the chassis consume significant amounts of power while the system is in standby
mode. The system fans will be run at 1541 rpm, or 38% of full speed, during standby to remove the resulting
heat from the cabinet. The fans within the power supply will operate at full speed during standby.
