With over 100K Rittal brand components, Pixus has virtually unlimited configurations of chassis platforms for embedded computing. Typical plug-in modules are 3U or 6U with a 160mm depth. OpenVPX, CompactPCI Serial, CompactPCI, VME, and VME64x are open standard backplane architectures commonly used in 19" rack-mount Eurocard enclosure systems. (For OpenVPX products, see the Pixus OpenVPX section.) Enclosures are available to hold these boards in front-to-rear, bottom-to-top, and for 6U and 8U boards there is side-to-side cooling options. The chassis can come with or without integrated fan trays or with redundant push-pull cooling. EMC versions are also standard.
