Heat Dissipation System of the ME60-X16

Heat Dissipation System of the ME60-X16

System Air Channel

The ME60-X16 supports four fan modules. Each fan module consists of one fan.

The ME60-X16 is divided into an upper chassis and a lower chassis; it draws in air from the front and exhausts air from the rear. 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 lower chassis and the upper chassis are opposites. The upper chassis and the lower chassis also have separate heat dissipation systems.

The middle area of the ME60-X16 is for SFU slots. The air intake vent of this area is located on the left of the chassis. Two upper SFU slots in the area draw in air from the left. When flowing to the right, the air joins the air from the upper chassis. Two lower SFU slots in the area also draw in air from the left. When flowing to the right, the air joins the air from the lower chassis.

Figure 9-11 shows the air flow in the ME60-X16.

Fan Speed Adjustment

This section describes the fan speed adjustment.

When the system is fully configured, temperatures reported by the temperature sensors on the LPUs, SFUs, and MPUs serve as the basis for fan speed adjustment. Table 9-15 lists general principles.

Table 9-15 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 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-X16 draws in air from the front and exhausts air from the rear. The two air filters on the upper and lower chassis are identical. To maximize air intake, the filters are fully perforated. Air filters are fixed to the chassis by fasteners to facilitate filter removal and replacement. Figure 9-12 shows the appearance of an air filter.

Figure 9-12 An air filter

The air channel in the SFU slot area is located on the left of the chassis. The air filter uses front access. 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 an SFU as shown in Figure 9-13.

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