Overview
Your openGear frame is a 2RU modular frame, designed to accommodate openGear cards. A complete
list of available openGear cards is available on our website.
Modular Frame Architecture
The openGear frame supports module-dependent rear modules. Rear modules can be ordered with
cards, and are easy and quick to install.
OG3-FR Series Frames
The OG3-FR series frames offers the flexibility of independent rear modules for connectivity to a
wide array of interfaces such as BNC, twisted-pair audio, and fiber. Using the split rear module allows
for up to 20 cards to be installed (noting maximum user net power of 300W limit).
Note that cards and rear modules designed for the 8321 series frames are also supported by the
OG3-FR series frames. However, some cards and rear modules may be designed specifically for the
OG3-FR series frames only. Refer to the documentation for your openGear card for details on the
frames you can use.
Robust Power Supply with Redundancy Option
The openGear frame can accommodate two front-loaded power supplies. However, each frame comes
standard with one power supply. 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.
Cooling
The openGear 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.
The OG3-FR series frame is designed with front-door mounted fans to 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 is available for the
frames.
