==== D-sub breakout at 52-7481B ====
The 52-7481B Central Power Rack 1U is equipped with 4 D-sub connectors which carry status signals for each [[https://dhd.audio/product/527482a/|52-7482A]] power supply unit. These D-sub connectors can be connected directly (1:1) to [[https://dhd.audio/product/526509a/|52-6509A]] GPIO modules. Usually these will be built into a [[https://dhd.audio/product/526500c/|Q-Panel]].
