The 2RU openGear modular frames are designed to accommodate up to ten openGear cards and provide maximum application flexibility. The 8310-C-BNC frame has the simplicity of a fixed rear connector frame with 100 BNC connectors. This eliminates the need for separate slot-dependent rear modules and simplifies pre-wiring and system expansion. Any openGear card using BNC connectors can be installed into any slot. Unused slots can be pre-wired into a facility, and additional cards can be installed at any time without accessing the rear of the frame.

The 8310-C frame, on the other hand, has the flexibility of independent rear modules for applications where other types of I/O connections (such as twisted-pair audio or fiber interfaces) are necessary. The frame also supports slotdependent rear I/O modules. Rear modules can be ordered with card modules and are quick and easy to install.

The openGear frames have been designed with an advanced cooling architecture and include front-door mounted fans provide forced air cooling for all cards and additional cooling for the power supplies. The intelligent fan controller adjusts fan speed with changes in frame power loading or temperature. Particular attention has been paid to frame acoustics in order to keep fan noise to a minimum.

Two looping reference inputs are buffered and distributed to all card slots. A frame mounted Ethernet port allows a network control module to be added without occupying a module slot.

A SMPTE 269M alarm monitoring connection is also provided. The frame can accommodate two front-loaded power supplies. Although a single supply can fully power a loaded frame, the addition of a second (optional) supply gives the frame full power redundancy. Each supply is fed by a separate power cord with a PowerLock cord retainer to guard against accidental power loss. Each power supply contains an independent cooling fan, status LED and a front-mounted power switch. One PS-8300 power supply is standard with each openGear frame.

The CB-8310-C has modular I/O panels for connector flexibility. The 8310-C-BNC frame has fixed 100-BNC rear panel.
