2.2.1 DFG48000 and DFG48000R chassis
The DFG48000 is a 19” rack-mountable Ethernet Switch with three eight port slots (A, B, and C) and
one Gb-only slot (D) for configuration flexibility. Slots A, B and C may be configured with any of a
large selection of fiber and copper port types and combinations of types, typically eight ports per
module, but sometimes 6 or 4 ports or even one Gb port. Slot D may be configured with a Gb module
that accepts GBICs. The port types configurable using the 4 slots allows the DFG48000 to efficiently
serve a large variety of applications, especially using fiber media. The DFG480XX port modules are
normally factory installed, but may be changed or added in the field. (See Section 5)
Figure 2.2.1a: “Regular” DFG48000 front view, configured for 24 + 1 GB ports Status LEDs are part
of each port module and are viewable when connecting the Ethernet media. A “regular” rack-mount
DFG48000 is shown in Figure 2.2.1a. On “Reverse” rack-mount models, there is a duplicate set of
LEDs on the other (front) side for normal status viewing from that direction. Of course, with
management, the port status data is also available in software.
