Dear Engineer,

Standard enclosure platforms - CompactPCI, AdvancedTCA, VMEbus, ATR (Air Transport Rack), and others - can be manufactured a number of ways.  Is it important to know how your enclosure is built? You bet.   Let's start with the most common types of construction used in benign environments.

What is VXS?

VXS is a switched serial backplane fabric for VMEbus defined by VITA specification 41, www.vita.com.  VXS payloads are standard VME64X boards with a new P0 connector which handles two 4X, full-duplex switched serial ports.  A VXS switch card connects payload cards and manages the crossbar switching.
