21-slot fully hybrid PXIe chassis

A new 21-slot chassis is available in a compact 4U form factor

The new chassis features one PXIe system slot and 20 hybrid peripheral slots in a compact 4U form factor.

The chassis has a high-performance 21-slot PXIe backplane and accepts PXIe (PXI Express) or standard PXI hybrid-compatible modules in all hybrid peripheral slots for application flexibility. The Gen2 chassis offers high data bandwidth, with up to 8 GB/s system and 2 GB/s slot-to-slot. Ultra-high performance PCIe switching is provided via the default four-link (4×4) capacity PXIe system slot. The chassis uses three PCI segments with a dedicated PCIe-to-PCI bridge module for the hybrid slots. The PXI-specific high-accuracy clocks and trigger signals are generated and controlled by an independent clock module attached to the rear of the backplane.

“Paired with our new single-slot embedded controller, this new chassis delivers high rack density for signal switching,” said Lee Huckle, Chassis Product Manager at Pickering Interfaces. “With the chassis accepting PXIe or standard PXI hybrid-compatible modules in all 20 hybrid peripheral slots, this enables up to 15,360 crosspoints using our BRIC large PXI matrix and multiplexer solutions.”

Fitted with dual swappable 900W EMC Class B industrial grade power supply units (PSUs) mounted at the rear of the unit, the chassis can provide up to 80W of power and cooling in every slot – sufficient capacity to support PXI modules with very high current demands. An intelligent chassis management system monitors PSU voltage, internal temperature, and cooling fan speed – and the current condition of the chassis can be monitored remotely via a port on the rear panel. Three 120 mm fans ensure maximum PXI module cooling, and an efficient direct convection design allows the chassis to operate over an extended ambient temperature range of 0°C to +55°C. With dual swappable PSUs and a removable rear cassette, servicing and maintenance has never been easier.
