The DFR-8321 is a 2RU high density modular frame, designed to accommodate up to 20 openGear
®
cards.
The 21st slot is reserved for network control.
MODULAR FRAME ARCHITECTURE
The DFR-8321 offers the exibility of independent rear modules for connectivity to a wide array of interfaces
such as BNC, twisted-pair audio, and ber. The DFR-8321 offers a full rear module that offers 10 BNCs per
module, or a high density split rear module that offers 5 BNCs per module. Using the split rear module allows
for up to 20 independent openGear
®
solutions to be installed.
ROBUST POWER SUPPLIES
The DFR-8321 can accommodate 2 front-loaded PS-8300 power supplies. A single supply can fully power a
loaded frame, the addition of a second (optional) supply gives the frame full power redundancy.
Each power supply contains an independent cooling fan, status LED, and a front-mounted power switch.
COOLING
The frame has been designed with an advanced cooling architecture with increased ventilation. The
front-door mounted fans provide forced air cooling to all cards with front to back cooling. An intelligent fan
controller adjusts fan speed with changes in power supply loading and temperature.
CONTROL
The DFR-8321 comes standard with Ethernet connectivity for basic conguration and monitoring of
openGear
®
cards through the DashBoard control system. An optional advanced networking card, the
MFC-8320-N, provides multiple DashBoard connections and adds advanced features such as DataSafe
and optional SNMP (see page 9 for more details).
