Heat Dissipation System of the ME60-X16A

Heat Dissipation System of the ME60-X16A

System Air Channel

The ME60-X16A supports a maximum of six fan modules. For a platform with forwarding capacity as 400 Gbit/s or below. Each fan module consists of six fans.

Figure 9-14 shows the locations of the fan module and the air intake vent.

The ME60-X16A provides three air channels. Each of the upper board cage and the lower board cage has an air channel. Both air channels draw air from the front and exhausts air from the rear. The SFU slot area has an air channel. The air channel draws air from the left and exhausts air from the rear top and rear bottom. The system draws air for heat dissipation. Figure 9-15 shows air flows.

Fan Speed Adjustment

This section describes the fan Speed adjustment.

When the fan tray assembly of a 1T or lower device rotates at its full speed, the maximum power of the fan tray assembly is 500 W.

When the system is in full configuration, the temperatures reported by the temperature sensors on the LPUs, SFUs, and MPUs serve as the basis for fan speed adjustment.

The 1T or lower device complies with the following principles.

Ambient Temperature Rotational Speed Noise and Dissipation Standards
-5°C - +27°C (23°F - 80.6°F) Low rotation speed (35%) When fans rotate at a constantly low speed and the fans meet heat dissipation requirements of a fully configured system.
27°C - 45°C (80.6°F - 113°F) Linear variation The fan speed is adjusted smoothly in linear mode, without a sharp increase in noises.
Over 45°C (113°F) High speed (100%) Fans rotate at high speed to meet heat dissipation requirements.

Fan Module

The fan module is located on the air exhaust vent.

STATUS

Green:

  • If the indicator blinks once every two seconds (0.5 Hz), the fan module is working properly.
  • If the indicator blinks four times every second (4 Hz), the fan module is registering.

Red:

  • If the indicator blinks once every two seconds (0.5 Hz), the fan module is faulty.

Orange:

  • If the indicator is steady on, the fan module is faulty.

Air Filter

A black sponge air filter on the air intake vent prevents dust from getting into the system. The air filter can be removed and cleaned. Cleaning air filters once every three months is recommended.

The ME60-X16A has three air filters, the locations of which are shown in Figure 9-16.
