Cooling

The operating temperature range for the RG-NBF6002M switch is 0° C to 50° C (32° F to 122° F). Its heat
dissipation design not only ensures the switch's reliability within this temperature range but also takes into
account safety and ease of maintenance. The switch is equipped with fans for forced convection to maintain
optimal performance and reliability in the specified operating conditions.
Note

Blue arrows: The air inlet direction of the line card and the power module.

Red arrows: The air outlet direction of the line card and the power module.
Line card/power module: The left, right, and front sides of the module are used for air intake, while the rear side
is used for air exhaust. The fans draw air outward to create convection for heat dissipation.
Caution

Ensure sufficient space around the chassis for air circulation and space for the air intake vent and air
exhaust (at least 10 cm). Ensure that there is adequate space around the chassis to allow for air
circulation, as well as space for the air intake vent and air exhaust, with a minimum clearance of 10 cm
(3.94 in.).

If a line card slot is not used, install a line card faceplate to the slot. If a power module slot is not used,
install a power module faceplate to the slot. Faceplates should be correctly installed to the chassis slots
to ensure proper airflow.
