1: Introduction
Advanced Power Management
The Intel Intelligent Power Node Manager (IPNM) provides your system with real-time thermal
control and power management for maximum energy efficiency. Although IPNM Specification
Version 1.5 is supported by the baseboard management controller (BMC), your system must also
have IPNM-compatible Manageability Engine (ME) firmware installed to use this feature. ME,
which is an ARC controller embedded in the IOH, provides Server Platform Services (SPS) to
your system. The services provided by SPS are different from those provided by the ME on client
platforms.
Special System Notes
With four serverboards acting as four separate nodes all incorporated into a single chassis, the
C2112-4RP9 server is a unique server system. These section describes some special notes
affecting these aspects of the configuration:
• Independent nodes
• System power
• SATA backplanes/drives
Independent Nodes
Each of the four serverboards act as a separate node in the system. As independent nodes, each
may be powered off and on without affecting the others. In addition, each node is a hot-swappable
unit that may be removed from the rear of the chassis. The nodes are connected to the server
backplane by means of an adapter card.
Note: A guide pin is located between the upper and lower nodes on the inner chassis wall. This
guide pin also acts as a stop when a node is fully installed. If too much force is used when inserting
a node, this pin may break off. When inserting a node, slowly slide the node in until you hear the
click of the locking tab seating itself.
