1. UPS Only: If you are installing a UPS and non-redundant power to
the device(s) is desired, plug all the equipment into the UPS output
receptacles using the power cords located in the power cord kit
(see Figure 31 on page 24). Distribute the load evenly between the
rows of receptacles on the UPS.
If you are installing a UPS and dual-redundant power to the
device(s) is desired, plug the minimum number of power cord(s)
required to operate the device into the UPS output receptacles
using the power cords located in the power cord kit (see Figure 32
on page 25). Then, plug the remaining (redundant) power cord(s)
into a non-UPS protected output receptacle (e.g., PDU or mains) or
a second UPS. Distribute the load evenly between the rows of
receptacles on the UPS.
NOTE The redundant power source must be protected with Transient Voltage Surge
Suppression (TVSS).
