Fans
The washable air filter is inside the front door of the cabinet. The air intake is from the front, and air
exhaust is from the rear and top.
Fan Tray
Four fans are located on a slide-out fan tray in the center of the cabinet, between shelves A and B.
The fan tray is a plug-in fan assembly used for system cooling. The fan assembly is accessible from
the front of the cabinet.
The four fans draw air through the front door air filter, and they exhaust from the top rear and top
sides of the cabinet. The fans use 12 volts and are powered from the +12 VM output of the PSU. The
fans are not sensitive to the input power to the cabinet.
