Avoid hot swapping, the act of removing and replacing the DMD with DMD power supplies and/or data inputs which are already energized, to ensure maximum reliability of the DMD. Never add or remove the DMD from a DMD socket unless all input power supplies of the DMD are at a potential equal to the local ground potential (VSS). This applies to a DMD incoming test station, a partially assembled product, a completed product under test, and a product in the field. This also applies to any cables, flex cables, or PCB connections which provide power to the DMD. Provide power as defined in the power-up scenario detailed in Section 9.1. Perform power down as defined in Section 9.2
