Heat Dissipation System of the ME60-X8

Heat Dissipation System of the ME60-X8

System Air Channel

The ME60-X8 supports two fan modules. Each fan module consists of one fan.

The ME60-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 ME60-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 9-6.

Fan Speed Adjustment

When the system is fully configured, temperatures reported by the temperature sensors on the Interface boards, SFUs, and MPUs serve as the basis for fan speed adjustment. Table 9-6 lists general principles.

Table 9-6 Fan Speed Adjustment Principles
Ambient Temperature Rotational Speed Noise and Dissipation Standards
-5°C - +27°C (23°F - 80.6°F) Low speed (50%) When fans rotate at a constantly low speed, the noises meet the standard and the fans meet heat dissipation requirements of a fully configured system.
27°C - 40°C (80.6°F - 104°F) Linear variation The fan speed is adjusted smoothly in linear mode, without a sharp increase in noises.
Over 40°C (104°F) High speed (100%) Fans rotate at high speed to meet heat dissipation requirements.

Fan Module

The fan modules, each containing one fan, are located side by side at the air exhaust vent.

Air Filter

The ME60-X8 draws in air from the front top and exhausts air from the rear top. There is a 3 U space in the upper part of the chassis and an air filter on the front of the chassis. To maximize air intake, the filter is fully perforated. The air filter is fixed to the chassis by a fastener to facilitate filter removal and replacement. Figure 9-7 shows the appearance of an air filter.

NOTE:

Placing a black sponge air filter on the air intake vent helps to prevent dust from entering the system. Cleaning the air filter once every three months is recommended.
