21-slot hybrid PXIe chassis is in compact 4U form factor
A 42-927 PXIe chassis offers 20 hybrid peripheral slots and is the latest addition to Pickering Interfaces’ PXIe chassis range.
The compact 4U form factor 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. The Gen2 chassis offers high data bandwidth, with up to 8Gbyte per second system and 2Gbyte per second slot-to-slot. 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.
When paired with Pickering’s recently launched 43-920-001 single-slot embedded controller, the 42-927 chassis delivers unrivalled 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 – the highest number of any chassis currently on the market – this enables up to 15,360 crosspoints using our BRIC large PXI matrix and multiplexer solutions,” he added.
The chassis is fitted with dual swappable 900W EMC Class B industrial grade power supply units (PSUs) mounted at the rear. It can provide up to 80W of power and cooling in every slot to support PXI modules with very high current demands. An intelligent chassis management system monitors PSU voltage, internal temperature, and cooling fan speed while the current condition of the chassis can be monitored remotely via a port on the rear panel.
Three 120mm 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 to +55 degrees C.
The chassis is complemented with dual swappable PSUs and a removable rear cassette, for ease of servicing and maintenance.
