Install and Configuration 2-9
Hardware Configuration
This section provides the System Processor Unit (SPU) hardware configuration information. This includes
the address paths, power loading and configuration limits for both HP 9000 and HP 3000 SPUs. The address
path information is needed to perform system configuration within the operating system software.
Address Paths
Tables 2-1, 2-2, and 2-3 list the internal address paths for the HP computers.
NOTE
There are no power loading considerations between the two I/O busses. The power supply in the SPU
is sufficient to accommodate the distribution across all I/O slot locations. The HP-PB Configuration
rules are for performance only.
