To ensure maximum reliability of the DMD, avoid hot swapping, which is removing and replacing the DMD with DMD power supplies or data inputs that are already energized. 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 that 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.
