Using Optional Power Systems 2-11
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.
To calculate the total power consumption of all units connected to the
Advanced RPS:
1 Calculate the total wattage of all the units connected to the Advanced RPS.
For example, one Hub 1000 SX has a maximum power consumption of
65 watts; two Hub 1000 SX units have a maximum power consumption
of 130 watts, and so forth.
2 Divide the total wattage of all units by 0.7, which is the efficiency rating
(70%) of the Advanced RPS.
If the result is less than 325 watts, your configuration is safe; if the result
is higher, then there are too many units connected to the Advanced RPS.
