1.1.5 Heat Dissipation System
This section describes the heat dissipation system components and the appearance, functions,
and technical specifications of fan modules.
1.1.5.1 System Air Channel
This section describes the system air channels and air flows of the USG9580.
The USG9580 has three air channels:
l
The upper and lower chassis have separate air channels that draw air from the front and
exhaust air from the rear. The air filters are installed over the air intake vents. Each filter
covers a large area and has a curved face and low windage resistance. These features
increase heat dissipation efficiency. The air filters on the upper and lower chassis are
identical.
l
The air channel in the SFU slot area is located on the left side of the chassis. The depth
of the air filter is the same as that of an SFU, and the height of the air filter is four times
the height of the SFU.
The air intake vent on the upper chassis is located above the board area on the front chassis;
the air exhaust vent is located above the board area on the rear chassis. The air intake vent on
the lower chassis is located below the board area on the front chassis; the air exhaust vent on
the lower chassis is located below the board area on the rear chassis. The upper chassis and
the lower chassis also have separate heat dissipation systems.
The middle area of the USG9580 is for SFU slots. The air intake vent in this area is located on
the left side of the chassis. Two upper SFU slots in the area draw in air from the left side.
