An AdvancedTCA board (blade) is 280&nbsp;mm deep and 322&nbsp;mm high. The boards have a metal front panel and a metal cover on the bottom of the [[Printed circuit board]] to limit [[Electromagnetic interference]] and to limit the spread of fire. The locking injector/ejector handle (lever) actuates a microswitch to let the Intelligent Platform Management Controller (IPMC) know that an operator wants to remove a board, or that the board has just been installed, thus activating the hot-swap procedure. AdvancedTCA boards support the use of [[PCI Mezzanine Card|PMC]] or [[Advanced Mezzanine Card|AMC]] expansion mezzanines.
