Stampa la paginaThe DFG48044X family of Edge Switches have a wide breadth of port configurability and fiber port type options -
six 10/100 copper ports or four 10/100 copper ports and two 100 Mb Fiber port or five copper ports with one
100Mb Fiber port built in, covers the full range of application environments, with regular (office), Hardened
(factory floor), and Rugged-rated (outdoor) versions. Extra features for heavy-duty and extended temperature
operation ranges are included selectively in the Hardened factory-floor and Rugged-rated outdoor models. The
breadth of models and flavor of fiber port types offers the best price-to-value ratio for each user and installation.
The compact package is ideal for network edge installations, and is able to be conveniently Din rail mounted to suit
any application.
The Dante Security Edge switches include Link-Loss-Learn (LLL) feature (factory configurable on ports 1
and 2 to qualify for any redundant and self-healing managed network structures. The Link-Loss-Feature in
DFG48044X allows the Edge switches to flush the internal address buffers in milliseconds to permit a quick change
in LAN packets flow, and pass the reconfiguration signal down the line to other ring switches in the redundant
structure for faster recovery. Dante Security Edge switches, combined with other Dante Security managed
switches, running STP/RSTP or S-Ring, can often provide high availability Redundant LANs at economical cost.
The DFG48044X regular-package units are for office and indoor wiring closet environments. These are the
economical base units in the DFG48044X Switch family. An external AC power supply for either North America or
international is included. The ambient temperature rating is 0°C to 40°C, office grade. The regular model,
DFG48044X, includes Link-Loss-Learn, MDIX ports and the full range of fiber port options. The regular DFG48044X
model does not have options for Alarm and DC power. The DFG48044XH Hardened units are for factory floor
applications. The DFG48044XH models are built with high-grade components and are constructed using special
thermal techniques and a metal case. The DFG48044XZ series are rugged rated units suitable for temperature un-
controlled outdoor applications. Specially designed with rugged-grade extended temperature components, the
DFG48044XZ units use similar thermal techniques to the DFG48044X hardened units for cooling. Mounting options
include panel-mounting or rack-mount tray. Choices of models for external AC or internal DC power are available.
Ambient operating temperature is between –40°C to +75°C depending on the power source used. Storage
temperature rating is between –40°C to +85°C.
hardware operated 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. The
DFG48044X series provides switching among four 10/100 auto-negotiating copper ports and two 100Mb fiber ports
which may be SC, ST, MTRJ or LC multi-mode or single-mode. The DFG48044X's breadth of fiber options and well
as temperature options provide many networking options and solutions in a very small footprint.
Two sets of LEDs to indicating the operating status of ports are mounted on the top and front (for extra viewing
advantage while rack-mounted). For each port, there is Link and Activity (LK/ACT) LED's on the top indicating that
the media cables are connected correctly and showing, by blinking, when there is traffic.
All the rugged and hardened models also come along with
