DFR-8300 Series User Manual (Rev. 2.0)
Overview
Your DFR-8300 series frame is a 2RU modular frame, designed to accommodate any openGear card. A
complete list of available openGear cards is available on our website.
Modular Frame I/O
The DFR-8310 series frame is available pre-installed with ten 10-BNC rear modules and the flexibility
of independent rear BNC connector modules.
For most applications which use BNC connectors, the DFR-8310 series frame configuration allows any
openGear card using only BNC connectors to be installed into any slot, without restrictions. Installation
of separate Rear Modules is not required. Unused slots can be pre-wired into a facility, and installation
of cards can be done at any time without accessing the rear of the frame.
For applications where other types of I/O modules are necessary (such as twisted-pair audio or fiber
interfaces), the frame also supports module-dependent Rear Modules. Rear modules can be ordered
with cards, and are easy and quick to install.
The DFR-8321 series frame supports module dependent rear modules.
Robust Power Supplies
The DFR-8300 series frame can accommodate two front-loaded PS-8300 power supplies. Although a
single power supply can fully power a loaded frame, the addition of a second (optional) power supply
gives the frame full power redundancy. Each power supply is fed by a separate power cord, which is
held in position to guard against accidental power loss.
Each power supply contains an independent cooling fan, status LED, and a front-mounted power
switch.
Each frame comes standard with one PS-8300 power supply.
Optional Cooling Fans
The DFR-8300 series frame has been designed with an advanced cooling architecture to increase
ventilation. An intelligent fan controller adjusts fan speed with changes in frame power loading.
Particular attention has been paid to frame acoustics in order to keep fan noise to a minimum.
• DFR-8310 series frames — For applications where the total card load is less than 40W,
the DFR-8310 series frame can be used without cooling fans. Frames should be mounted
with 1RU empty space between frames. For applications where frames are mounted
directly above or below other equipment, or where the total card power load is greater
than 40W, an optional cooling fan kit must be added. These front-door mounted fans
provide forced air cooling for all cards, and additional cooling for the power supplies.
• DFR-8321 series frames — The frame has been designed with an advanced cooling
architecture to increase ventilation. These front-door mounted fans provide forced air
cooling for all cards, and additional cooling for the power supplies.
Additional Frame Accessories
To help reduce mechanical stress due to cable weight, a rear frame support bracket (FSB-8310) is
available for the DFR-8310 series frames. The rear support bracket (FSB-8320) is for the DFR-8321
series frames.
