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.
