Chapter 1. Reference Information

This chapter provides reference information for the Model D10 and Model D20 I/O
subsystems.

pSeries 7311 Model D10 Overview

The Model D10 is a 19-inch, rack-mountable I/O subsystem that is attached to a
processor subsystem drawer to extend the system's capacity for I/O adapters. The I/O
drawer includes redundant concurrently maintainable power and cooling.
Five PCI-X slots and one PCI slot are available for PCI adapters. PCI adapters are
installed through the rear of the I/O subsystem using PCI adapter cassettes. Because
the PCI slots support hot-pluggable adapters, the I/O subsystem can have adapters
installed without turning off power or removing covers. The Model D10 is 4 EIA units
high and two Model D10s can be installed side-by-side in a 19-inch rack enclosure.
