What is tnPowerSupplyPresent?
This read-only TruthValue object reports whether a power supply module is physically installed in the slot identified by tnPowerSupplyIndex in the same table row. Admins check this to distinguish an empty power supply bay from one where an installed unit has actually failed, which changes how urgently the situation needs attention. For example, this field reading false for a redundant power slot would tell an admin a module needs to be physically installed there, separate from any power-related alarm.
