The device has one fan tray and one air filter that install vertically in the rear of the device.
Two types of fan trays are available:
The standard capacity fan tray has three fans that operate at 216 cubic feet per minute (CFM) at full
speed and is adequate for services gateways in which standard-capacity power supplies are installed.
The high-capacity fan tray has three fans that operate at 289 cubic feet per minute (CFM) at full speed
and is required when high-capacity power supplies are installed.
The air intake to cool the chassis is located on the side of the chassis next to the air filter. Air is pulled
through the chassis toward the fan tray, where it is exhausted out the side of the system. The air intake
to cool the power supplies is located in the front of the device above the craft interface. The exhaust for
the power supplies is located on the rear bulkhead power supplies.
Each fan has an LED that displays its status. The fan LEDs are located on the top left of the craft interface.
