Cleanliness

Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of
metal components and contact points, especially when indoor relative humidity is low. In the worst
case, electrostatic adsorption can cause communication failure.

Dust particles
NOTE:
Dust particle diameter ≥ 5 µm
The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion
and premature aging of components, as shown in

Cooling system

The router uses left to right airflow for heat dissipation.
To ensure good ventilation, the following requirements must be met:
•
Leave a minimum clearance of 100 mm (3.94 in) at the inlet and outlet air vents.
•
The installation site has a good cooling system.
