Side Panels
The left side panel of the Switch contains four system fans. The right 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 adequate 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.
