Heat Dissipation System of the ME60-X8A

Heat Dissipation System of the ME60-X8A

System Air Channel

The ME60-X8A supports a maximum of three fan modules. For a platform with forwarding capacity as 400 Gbit/s or below, only two fan modules need to be configured. For a platform with forwarding capacity as 1 Tbit/s, three fan modules need to be configured. Each fan module consists of six fans.

Figure 9-8 shows the locations of the fan module and air intake vent on the ME60-X8A.

1. Air intake vent

2. Fan module

The system draws air from the front and discharges air from the back. The air intake vent resides above the board area on the front chassis; the air exhaust vent resides above the board area on the rear chassis. The system draws air for heat dissipation. Figure 9-9 shows air flows.

The air filters on the air intake vents are vertically installed and featured with the curved face, large area, and small windage resistance, helping to improve the heat dissipation efficiency.

Fan Speed Adjustment

When the system is configured to the largest capacity, the fan rotation speeds are adjusted based on the temperatures reported by the sensors on the SRUs, Interface boards, and SFUs.

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

Ambient Temperature Rotational Speed Noise/Heat Control
Below 27°C (75.2°F) Low rotation speed (35%) When the ambient temperature is below 27°C (75.2°F), fans rotate at a fixed low speed, which meets the noise requirement and the heat dissipation requirement.
27°C-40°C (75.2°F-104°F) Linear speed adjustment When the ambient temperature is between 27°C (75.2°F) and 40°C (104°F), the fan rotation speeds are adjusted smoothly in linear mode, and the fan noise does not change violently.
Above 40°C (104°F) High rotation speed (100%) When the ambient temperature is above 45°C (104°F), fans rotate at a fixed high speed, which meets 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.
