System Board

The interconnect switch is implemented on the system board

by the chipset consisting of one C-chip, two P-chips, and eight

D-chips. This complex chipset provides the data and address

path between the CPUs, memory, and the I/O subsystem.

A flash ROM holds the AlphaBIOS console code, the SRM

console code, and the NVRAM data.

Connectors are provided for four CPU modules and four

memory motherboards.

One corner of the board holds logic for the remote

management console (RMC).

On the back side of the module are connectors for the power

supplies. The I/O connector provides both signals and power

to the PCI backplane.
