98 iSeries and AS/400e System Builder
PCI IOP controllers
PCI Rules PCI cards are subject to plugging rules. 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 guides when configuring IOAs and input/output processors (IOPs) so that the system is sized
to meet client expectations. Refer to Chapter 7.1, “PCI card placement for iSeries servers” on page 224, for an introduction
to PCI.
Embedded
IOP
Embedded 32 MB Base PCI IOP
The embedded I/O processor is standard on every 270 system tower and the #5075 PCI Expansion Tower. This IOP is
embedded and, therefore, does not require a PCI card slot. Provides support for maximum of up to four IOAs, including
the SCSI IOA #9767 Base PCI Disk Unit Controller, the #9771 Base PCI Two-Line WAN with integrated modem, and
system console options. See the #2842 PCI IOP description for a list of other cards supported. See PCI Card Placement
Rules for the IBM eServer iSeries Server, REDP-3638 for plugging rules.
#2842 #2842 PCI IOP
The #2842 is a PCI I/O processor with 32 MB of memory which drives PCI IOA adapters on the Model 270 and on the
#5075 PCI Expansion Tower. The #2842 can drive up to four IOAs.
The following IOAs are supported (driven) by the embedded PCI IOP and the #2842 PCI IOP:
#2742 2-Line WAN IOA
#2743 1 Gbps PCI Ethernet IOA
#2744 PCI 100 Mbps Token Ring IOA

#9767 Base PCI Disk Unit Controller
Maximum: Two in the 270 system unit; three in a #5075 PCI Expansion Tower
The #2842 is a Customer Install Feature.
The #2842 was withdrawn from marketing on 21 November 2003.
