Power Connections and Startup

The device power cord connection(s) determines if the setup can
provide dual-redundant power to the protected device(s). See Figure 15
for a non-redundant powered device; Figure 16 shows a dual-redundant
powered device. See Table 7 on page 17 and Figure 18 through
Figure 19 beginning on page 19 for specific power connections.

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 15) 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 16) 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.
