Cooling
The router provides front-to-rear airflows. Plan and build the ventilation system at the installation site
carefully to ensure adequate cooling for the device. Make sure the following requirements are met:
•
The installation site has a good cooling system.
•
The air conditioners do not blow air directly onto the router.
•
The rack for the router can provide adequate cooling and ventilation, with the perforation rate of
rack doors greater than 50%.
•
The air inlet and outlet vents of the router are not blocked and adequate clearance is reserved
around the air vents.
