Configuring HP-UX For Peripherals

Appendix B 261
Bus Architectures
Series 800 Bus Architecture
• MUX-based multi-function I/O card, containing single-ended SCSI,
parallel port, and 8 or 16 RS-232-C ports for console, access port for
remote console, and other serial devices.
• LAN-based multi-function I/O card containing 802.3 LAN, serial
connection for PowerTrust UPS, and remote modem access port with
security option to defeat inadvertent system resets (control-B MUX
defeat switch).
Table B-1, “Hardware Addresses of Multi-Function I/O Cards,” shows the
hardware addresses for a sample Model E multi-function card.
Figure B-4, “Typical I/O Addressing for a MUX/SCSI Multi-Function
Card,” shows how multiple functions on Model E map to the bus
architecture. (Note, this figure shows a detail of Figure B-3, “HP 9000
Model E Bus Relationships.”)
