3.1. Main Features
The main features of the CC121 CompactPCI crate include :
• 19 inch rack-mount crate, 9U high, 21 vertical slots with System Slot at the left and 20 Peripheral Slots.
• CompactPCI (PICMG 2.0 R3.0) 6U and 3U module compatibility. The Backplane has three segments of
seven slots linked with two CompactPCI bridge modules. These bridges are plugged on the rear of the
backplane and all the slots are available for the application with complete access from the front side. The
Backplane is equipped with P1 and P2 connectors, with V I/O to 3.3 V and 3.3 V coding keys assembled. A
CompactPCI 3U module must be used with the optional XC100 Slot Adapter. The crate accepts PXI
modules, but does not provide PXI-specific features.
• Optimized cross-flow air circulation. Power supply and module slots are cooled separately and fully
protected against over-temperature.
• Meets the IEEE 1101.10 standard for EMC compatibility and optimized cooling.
• Front panel Power Switch.
• Quality 1260W usable power supply with universal AC input, power factor correction, auto-voltage and
auto-frequency ranging.
• Derating (DEG) and Supply Fall (FAL) signals provided from the power supply to backplane System Slot
(P2 connector).
• Handles on the front and rear sides for easy handling
• Removable feet for bench-top applications and in rack-mount applications, four M4 size holes are provided
on the rear panel for their storage.
