Table 2-4 Advanced RPS Configuration Options
You can connect a UPS unit to an Advanced RPS unit as long as you do not exceed the maximum wattage 325 watts for the UPS unit. To verify that the UPS unit’s maximum wattage is not exceeded, calculate the total power consumption of all units connected to the Advanced RPS. If the result is less than 325 watts, your configuration is safe if the result is greater than 325 watts, then there are too many units connected to the Advanced RPS
