Side Panels; Led Indicators - D-Link DES-1218 User Manual

Side Panels

The right side panel of the Switch contains two system fans. The left side panel
contains heat vents.
The system fans are used to dissipate heat. The sides of the system also provide heat
vents to serve the same purpose. Do not block these openings, and leave at least 6
inches of space at the rear and sides of the switch for proper ventilation. Be reminded
that without proper heat dissipation and air circulation, system components might
overheat, which could lead to system failure.
