Chapter 2. Installing the pSeries 650
Service representatives use the procedures in this chapter to set up your pSeries 650.
Note: This procedure explains how to attach the mounting hardware to the rack enclosure. If your pSeries
650 was preinstalled in the rack, perform the rack-installation procedures as described in the 7014
Model T00 Rack Installation and Service Guide, order number SA38-0577, then return here and
begin with "Step 5. Are All of the Features Installed?" on page 16.
pSeries 650 Overview
The pSeries 650 is a multiprocessor, multibus system packaged in one 7038 Model 6M2 system drawer
and up to eight I/O drawers. The processor subsystem drawer is 8 EIA units high and can be mounted in a
19-inch rack. The 7038 Model 6M2 system drawer houses the processors, memory, and a base set of I/O.
The I/O capacity of the system can be expanded by the addition of up to eight I/O subsystems.
The pSeries 650 system supports up to eight logical partitions. Processors, memory, and I/O within each
partition can be dynamically removed or added without the need to reboot the system. Logical partitioning
requires the use of a hardware management console (HMC) that is used to manage and monitor the
system resources as well as provide a service focal point.
Cables are used to connect the base system to the I/O subsystem drawers, including the following:
v SPCN (System Power Control Network) cables.
v RIO (Remote Input Output) cables.
Power is connected to the pSeries 650 through redundant power cords that attach to redundant type-7
power distribution buses (PDBs), which are installed in the rack.
