The #2842 can drive a maximum of four IOAs, subject to further restrictions as stated in these
IOP descriptions. Further restrictions apply, as stated in the “PCI Card Placement Rules”
chapter of the
iSeries and AS/400e System Builder
, SG24-2155.
#2843/#9943 PCI IOP
The #2843/#9943 is an PCI I/O processor with 64 MB of memory that drives PCI IOA
adapters on Models 820, 830, 840, SB2, and SB3 on the #5075 PCI Expansion Tower when
attached to the Model 820, the #5074 PCI Expansion Tower, the #5079 1.8m PCI I/O
Expansion Tower, and the #5078 PCI Expansion Unit.
Up to five feature #2843 PCI IOPs may be added to the Model 820 System Unit. The #5075,
when attached to a Model 820, can contain or support up to three #2843 PCI IOP features.
On Models 830, 840, SB2, and SB3, a PCI IOP is not embedded on the backplane, but a
#9943 PCI IOP is included as “base” with the system. Up to four feature #2843 PCI IOPs may
be added in the system unit of Models 830 and 840. Up to two feature #2843 PCI IOPs may
be added in the system unit of Models SB2 and SB3. On the #5074 PCI Expansion Tower, a
PCI IOP is not embedded, but a #9943 PCI IOP is included as “base”. Up to five #2843 PCI
IOP features may be added to a #5074. Up to six #2843 PCI IOP features may be added to a
#5078.
