The DC power and AC power of the device will back up each other immediately when one of the power
sources fails. If both power sources fail, unplug the switch. When the power source has been restored, plug
the switch's power back in.
NOTE: the Power Modules all support a specific airflow direction. This air-flow direction must be the same as
the Fan Module installed. By default the airflow direction of the Power Module and Fan Module installed is
front-to-back.
Installing Fan Modules into the Fan Module Ports
Located on the rear panel of this switch there are three fan module ports.
The user can easily remove and insert fan modules into these ports.
Switch Connections
Switch to End Node
End node is a generic name for edge networking devices that will be connected to this switch. Typical
examples of end nodes are Personal Computers (PCs), Notebooks, Access Points, Print Servers, VoIP
Phones and more. Each end node will be outfitted with a 10/100/1000 Mbps, RJ-45, networking port.
Normally end nodes will connect to this switch by using a standard twisted-pair, UTP/STP, network cable.
After a successful connection, the corresponding Link/Act light will illuminate and blink to indicate that packet
activity is taking place on that port.The diagram below displays a typical end node connected to the Switch.
