2.10.1 Service processor - base

The PPC405 core features a five-stage pipeline instruction processor and contains 32-bit general purpose registers. The flash ROM contains a compressed image of a software load.

The SP base unit offers the following connections:

￿Two Ethernet Media Access Controller3 (MAC3) cores, which is a generic implementation of the Ethernet Media Access (MAC) protocol compliant with ANSI/IEEE 802.3, IEEE 802.3u, ISO/IEC 8802.3 CSMA/CD Standard. The Ethernet MAC3 supports both half-duplex (CSMA/CD) and full-duplex operation at 10/100 Mbps. Both Ethernet ports are only visible to the service processor.

￿Two serial interfaces, which are accessible only though the serial ports of p5-570 on the rear side. At the time of writing, the System Management Interface (SMI) is usable if a connection is established to serial port 1. Terminals that are connected to serial port 2 receive only boot sequence information without manual interaction. When the HMC is connected to the SP, the serial ports are disabled and do not provide any external connection.

2.10.2Service processor - extender

The SP extender unit offers the two system power control network (SPCN) ports to control the power of the attached I/O subsystem. The SPCN control software and the service processor software are run on the same PPC405 processor.
