1 User Guide (this manual) Remove the DFG48044X Series Edge Switch from the shipping container. Be sure to keep the shipping container should you need to ship the unit at a later date. In the event there are items missing or damaged contact your supplier. - Page 5 Alarm terminal block for providing extra reliability to the unit. The Alarm feature allows the DFG48044X users to be aware and to monitor any internal power failure. See section 44 for details. The front side of the unit has four/five twisted-pair 10/100Mb switch ports and one/two 100Mb fiber port. All the RJ-45 ports of the DFG48044X Series Edge switches support auto-cross (MDIX) operation under auto-negotiation mode.

Two sets of LEDs for viewing status from any angle. Each DFG48044X Series Edge Switch is equipped with two sets (front and side) of LEDs to provide status information when viewed at almost any angle or mounting arrangement whether rack (MC14- Tray) or Din-Rail mounted. -
Page 8: Applications For Dfg48044X Series Edge Switches
Example: In this example, the Dante Security DFG48044X rugged Edge Switches are deployed to serve as a secure corporate or transportation surveillance system. CCTV cameras may be spread out over many miles in temperature un-controlled locations and with pan, tilt and zoom (PTZ) controlled through an Ethernet copper port. -
Page 9: Installation
In a typical installation, the MC14-TRAY, 19” rack-mount tray will hold a few (three to eight) DFG48044X Series Edge Switches, with their power supplies plugged into power strips in the rear area of the tray. Metal mounting screws in the bottom-front hold the Edge Switches firmly in place. -

Cards) which support Auto-Negotiation, and the Fast Link Pulse (FLP) coding for the 100BASE-TX signaling system. When connecting a NIC to the DFG48044X, it may be necessary to reload the NIC drivers on the user device if the NIC has been communicating with a protocol other than 100BASE-TX (such as 10BASE-T). When... -
Page 15: Operation
The switched RJ-45 ports are full- or half-duplex auto-sensing for mode and speed, and auto-cross for plug polarity (See Section 4.2). When the connected device is 10 Mbps, the DFG48044X obeys all the rules of 10 Mbps Ethernet configurations. The 10 Mbps users can “communicate” with 100Mbps users as well as other 10 Mbps users through the switch. -
