DES-1218/DES-1226 10/100/1000 Mbps Ethernet Switch User’s Guide

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.
