7.1 PCI card placement for iSeries servers
The implementation of Peripheral Component Interconnect (PCI) architecture in iSeries
servers provides flexibility in the placement of input/output processors (IOPs) and
input/output adapters (IOAs). This can result in a more efficient use of card slots, which in
turn can lower the cost of implementation. For example, a specific PCI IOP can support two
high-performance IOAs, or four slower IOAs. However, it might not have the capacity to
support one high-performance IOA and two slower IOAs.
PCI architecture changes the configuration rules associated with card placement in IBM
iSeries Models 270, 820, 830, and 840 servers. Earlier models required IOPs to be in specific
slots in the system and expansion towers. However, increased configuration flexibility
reinforces a requirement to understand the detailed configuration rules.
The PCI Card Placement Rules for the IBM Eserver iSeries Server Version 5 Release 3,
REDP-4011, and PCI Card Placement Rules for the IBM eServer iSeries Server, REDP-3638
describes the configuration and card placement rules that you must understand and follow to
develop valid configurations. Use these IBM Redpapers as a guide when configuring IOAs
and IOPs to size the system to meet client expectations.
For rules related to the #5033, #5034, #5035, and #5077 Migration Towers that can attach to
Model 820, 830, and 840 servers, see the description of the affected features to be migrated
in Chapter 8, “IBM iSeries towers schematics” on page 293 or in the iSeries Information

7.2 Power and packaging
Important: If the configuration rules and restrictions are not fully understood and followed,
it is possible to create a hardware configuration that does not work, marginally works, or
quits working when a system is upgraded to future software releases.
Power and packaging
#0006 #0006 LPAR Restrict Build Process
The #0006 is added to an initial order where #0140 Logical Partitioning Specify is requested. This #0006 instructs
manufacturing to only load SLIC on the minimum number of disk drives.
This #0006 is mutually exclusive with #5000 SW Preload and with #0205 RISC- to RISC migration.
Supported on Models 820, 830, 840.
#0092 External xSeries Attach Specify
The #0092 is used to specify the number of External xSeries Servers connected to the system. The IBM marketing
configurator uses this specify code to determine the number of high-speed link (HSL) and System Power Control Network
(SPCN) cables required and to ensure that the number of External xSeries Servers does not exceed the system limit. Each
External xSeries Server is connected using HSL cables and attached to the SPCN string like all other HSL attached I/O
towers.
Prerequisite: A 1519-100 Integrated xSeries Adapter for iSeries or 1519-200 Integrated xSeries Adapter for i5 is required
in each External xSeries Server attached.
Supported on Models 820, 830, 840
Minimum operating system level: OS/400 V5R1 for 1519-100 Integrated xSeries Adapter for iSeries
