PSU Address Lines A0
Address pins A0 is used by end use system to allocate unit address to a power supply in
particular slot position.
particular slot position.
For redundant systems there are two signals to set the address location of the power supply
once it is installed in the system; Address0 and Address1. For non-redundant systems the
power supply device address locations should align with the Address0/Address1 location of 0/0.
