Side Panels

The right side panel of the Switch contains two system fans (see
the top part of the diagram below). 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.

Optional Plug-in Modules

The DES 3326 24-port Fast Ethernet Layer 3 Switch is able to
accommodate a range of optional plug-in modules in order to
increase functionality and performance. These modules must be
purchased separately.
