About the Power Distribution Unit

Introduction

A Power Distribution Unit (PDU) is installed in a rack that has DC-powered servers. Power from the DC supply source enters the PDU and can then be distributed to one or more servers. A single PDU can supply DC power to four DC power supply modules. A server can have either one or two power supply modules installed. You can determine the number of PDUs to install in a rack by counting the number of power supply modules in each rack.

Multiple PDUs

A server operates on a single power supply module. Its total capacity is two installed power supply modules. The second power supply module is the redundant power supply module.

A PDU can distribute power to a maximum of four power supply units that can be installed in two or more servers. Therefore, if there are three or four servers installed in a rack, then you must install a second PDU.

Note: The power supply module installs in the server. It does not refer to a UPS, which is a separate unit on the rack.
