Customized PDU Configurations
Frequently, PDU configurations can be changed to support special requirements. For
assistance with unique requirements and non-typical PDU configurations please email
your questions and configurations to
power@ lenovo.com . The appropriate personnel
will review and advise on the proper PDU solution which meets the customer’s needs.
Completing this step will help minimize the official power review time when the
solution becomes a Special Bid.
For official sign-off and review of custom PDU configurations, the complete
configurations must go through the Special Bids process. Email
power@lenovo.com
for the WW Complex Solutions Special Bids process and how it works.
Typical PDU Configurations
The following figures are examples of the connections from Single-phase and Three-
phase PDUs for a x3850 X6. These meet the X6 power supply label ratings, and is an
example of what is possible, although other valid configurations can be designed.
1400W PSU Configuration Diagrams
The 1400W power supply is covered in the following section for both North America
and International connection to supported PDUs. AC source redundancy, power
supply redundancy and non-redundant scenarios are covered. For the following
figures, the following applies:
 N+N refers to AC source redundancy.

N+1 refers to power supply redundancy.
 N refers to the system having enough power supplies to support the
configuration budget and all supplies are connected to the same AC source.
Refer to the Reference Material on page 96 for additional clarification on N+N, N+1
