Chapter 1. Introduction
The switched and monitored 1U PDU products enable you to connect up to nine C19 devices or up to 12
C13 devices (depending on the PDU model) and an additional three C13 peripheral devices to a single
dedicated power source. The PDUs have power monitoring capabilities.
The following PDU models are available:
• 46M4002 - 1U 9 C19 / 3 C13 Switched and Monitored DPI PDU (with removable power cord)
• 46M4003 - 1U 9 C19 / 3 C13 Switched and Monitored 60 A 3 Phase PDU (with attached power cord)
• 46M4004 - 1U 12 C13 Switched and Monitored DPI PDU (with removable power cord)
• 46M4005 - 1U 12 C13 Switched and Monitored 60 A 3 Phase PDU (with attached power cord)
The IBM Systems Director Active Energy Manager product can monitor and control the PDUs. Active Energy
Manager is an IBM Systems Director plug-in that measures and reports server power consumption as it
occurs. Active Energy Manager includes a feature to associate IBM Systems Director managed resources
with the power outlets on the PDUs. This enables you to know how much power each server is consuming
and which servers will be affected by any PDU outages. You can use the graphing capability of Active Energy
Manager to show a trending line for power that is being drawn by the outlets of the PDU models, showing
which systems are connected to them.
Active Energy Manager also enables you to show a trending line for the temperature of the PDU and the
temperature that is measured by the environment sensor. In addition to monitoring, Active Energy Manager
can control power of the individual outlets. From a central location, Active Energy Manager can power off or
power on the outlets. This enables an administrator to prevent someone from connecting additional
equipment into unused outlets, thereby making it easier to control power consumption within a rack. Active
Energy Manager can also shut down outlets in an emergency situation.
If firmware and documentation updates are available, you can download them from the Lenovo website. The
PDU might have features that are not described in the documentation that comes with the PDU, and the
documentation might be updated occasionally to include information about those features, or technical
updates might be available to provide additional information that is not included in the PDU documentation.
