5.2.8 Intelligent Platform Management Controller
The Renesas H8S/2166 provides the IPM controller (IPMC) function on the Netra
CP3260 blade server. The IPMC provides PICMG 3.0 blade server management
functionality, and it interfaces to the host CPU through a serial interface. The IPMC
subsystem is powered from the standby power.
The IPMC is responsible for the following:
■ Dual-buffered IPMB interfaces to connect to IPMB-0
■ Serial payload interface to the host through PPC
■ IPMI_L interface to communicate with MMC on ARTMs
■ Power control of the entire Netra CP3260 blade server
■ Power and reset control of the AMC board
■ Hot-swap latch input and LED control
■ Power control
■ E-Keying control
