1.9.3 Heat Dissipation System of the NE40E-X8

1.9.3.1 System Air Channel

The NE40E-X8 supports two fan modules. Each fan module consists of one fan.
The NE40E-X8 draws in air from the front and exhausts air from the rear. The air intake vent
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 two fan modules of the NE40E-X8 are located side by side on the air exhaust vent, with
each module containing one fan. The entire system dissipates heat by drawing in air, as shown
in Figure 1-81.

The air filter of the NE40E-X3A can be bent, which facilitates the maintenance within a limited space in
the rear of the chassis.
Placing a black sponge air filter at the air intake vent helps to prevent dust from entering the system. It is
recommended that the air filter be removed and cleaned once every three months.
