UPS Only: If you are installing a UPS and non-redundant power to
the device(s) is desired, plug the PDU power cord into the UPS
output receptacle (see Figure 28 or Figure 30) using the supplied
power cord.
If you are installing a UPS and dual-redundant power to the
device(s) is desired, two PDUs are required. Plug the first PDU
power cord into the UPS output receptacle (see Figure 29 or
Figure 31) using the supplied power cord. Then plug the second
(redundant) PDU power cord into a non-UPS protected output
receptacle (mains) or into a second UPS.
