• I/O slots:

• Local Bus Adapter:

Adapter, and thence to a cell; see “Cell Connectivity” on page 308.
• Monarch CPU:
The processor that performs selftest and other functions when a cell
is activated as part of a booting partition. See “What Happens when a

• PCI cards:
Peripheral Interface Cards, often called simply “I/O cards”; see “I/O

• PDC:
Processor Dependent Code. See “What Happens when a Cell Boots”
on page 311.
• Partition:
A cell, or usually group of cells, running an instance of an operating
system in a Complex; see“What is a Partition?” on page 298.
• Partition Manager (parmgr):
A menu-driven software tool (/opt/parmgr/bin/parmgr) that runs

Can can be executed locally on a partition, or remotely from a PC via
a web browser.
