Chapter 1. General description

Each power cord provides unique design characteristics for the specific power requirements.
To match new power requirements and save previous investments, these power cords can be
requested with an initial order of the rack or with a later upgrade of the rack features.
Table 1-21 lists the available wall power cord options for the PDU and iPDU features, which
must be ordered separately.
Table 1-21 Wall power cord options for the PDU and iPDU features
The Universal PDUs are compatible with previous models.
To better enable electrical redundancy, each server has two power supplies that must be
connected to separate PDUs, which are not included in the base order.
For maximum availability, the best way is to connect power cords from the same system to
two separate PDUs in the rack, and to connect each PDU to independent power sources.
For detailed power requirements and power cord details, see “Planning for power” at the IBM

Notes: Ensure that the appropriate power cord feature is configured to support the power
that is being supplied. Based on the power cord that is used, the PDU can supply from
4.8 kVA to 19.2 kVA. The power of all the drawers plugged into the PDU must not exceed
the power cord limitation.
Redundant power supplies: The second power supply for the Power 720 server is
optional and not included in the base order.
