Switch for proper ventilation. Be reminded that without proper heat dissipation and air circulation, system components
might overheat, which could lead to system failure.

The right-hand side panel of the DES-3552 and DES-3528P Switches contain two system fans and ventilation along
the entire right side. The left hand panel includes a heat vent. The system fans are used to dissipate heat. Do not
block these openings on either side of the Switch. 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.

Gigabit Combo Ports

In addition to the 24/48 10/100 Mbps ports, the Switch features two Gigabit Ethernet Combo ports. These two ports
are 1000BASE-T copper ports (provided) and SFP ports (optional). See the diagram below to view the two SFP port
modules being plugged into the Switch. Please note that although these two front panel modules can be used
simultaneously. At the same time, only one copper port or one SFP port can link up for each combo port. The SFP
port will always have the highest priority.
