power connector is a standard three-pronged connector that supports the power cord. Plug-in the female
connector of the provided power cord into this socket, and the male side of the cord into a power outlet. The

device. Insert the lock into the notch and turn the key to secure the lock.
Side Panel Description
The left- and right-hand panels of the Switch have heat vents to dissipate heat. 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.
Gigabit Combo Ports
The DES-1210-52/ME features four Gigabit Ethernet Combo ports. These ports are 1000BASE-T copper
ports (optional) and Small Form Factor Portable (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, the ports must be different. The SFP port will always have the highest
priority.
