of any damage that you believe occurred during shipment or delivery. Inspect the contents of this
package for any signs of damage and ensure that the items listed below are included. This package
should contain:
1 DFG48000 Managed Fiber Switch, base unit (configured with user-selected port module options)
1 AC Power Cord (U.S. only) 1 Set of metal “Ears” for 19” rack mounting 1 Installation and User
Guide (this manual) 1 Product Registration Card Remove the items from the shipping container. Be
sure to keep the shipping container should you need to re-ship the unit at a later date. To validate
the product warranty, please complete and return the enclosed Product Registration Card to Dante
Security, Inc. as soon as possible. In the event there are items missing or damaged, contact the
party from whom you purchased the product. If the unit needs to be returned, please use the original
shipping container if possible. Refer to Section 6, troubleshooting, for specific return procedures.
2.2 Product Description – DFG48000 Managed Fiber Switch
The DFG48000 Managed Fiber Switch boosts the performance of large Ethernet LANs, typically
serving as a “backbone” switch. It has the flexibility to handle a mix of both fiber and twisted-pair
switched ports along with Gigabit backbone port options. Industry-standard IEEE 802.1p QOS
prioritization is included, providing high performance switching services for both “smooth” streaming
and “bursty” data traffic. The DFG48000 has up to 25 ports capacity, all of which may be configured
as fiber ports, but still offers a space-saving rack-mount chassis that is only 1U (1.70in. or 4.32cm)
high. The “mixed-media” capability allows user selection of all popular flavors of fiber port connectors
and modes, including even 10 Mb fibers along with Gigabit ports. It also allows a mix of 10/100Mb
RJ-45 (copper) ports and a fiber Gigabit port in the same unit. This flexibility is achieved via a family
of DFG480XX port modules for copper and fiber-built-in (emphasizing Small Form Factor fiber for high
fiber port density), 6-port modules for fiber and RJ-45 combinations, and 1 GB port module selections
using GBICs. These modules can be factory configured in a base chassis unit (or may be changed in
the field by trained technicians) to adapt the unit to the user’s application and Ethernet cabling
requirements. Even evolving mixed-media requirements for 10Mb and 100Mb fiber and copper as well
as Gigabit ports can be handled by the DFG48000 product.
The chassis mounting rack style may be “regular” (with the ports and LEDs in the front and the power
input and management console connector in the rear) or “Reverse” (with the ports and LEDs and the
power-input and the management console connector all in the rear and a duplicate set of LEDs in the
front). Rack widths accommodated include standard 19” and input power may be AC. Designed for
use in network traffic centers, the DFG48000 Managed Fiber Switches are easy to install and use.
Addresses of attached nodes are automatically learned, maintained and aged out, adapting the
switching services to network changes. LEDs provide status information on each port. The DFG48000
provides high performance plug-and-play hardware operation, 802.1p packet prioritization in
hardware, and industry-standard managed networks software functionality in convenient 1U rack-
mount packages.
