Remove the top cover on the power supply. I think on mine there is a
board legend either on the top of the cover or on the inside of the
cover after you remove it. If you have a jumper board installed the
battery backup option is not installed, and if the jumper board is not
installed I believe there is an inverter board and a battery charger
board installed as part of the battery backup option. That's from
memory and I'd either need to look inside my own systems or find the
right manual to look at to verify I have that correct.
