#2843/#9943 PCI IOP

The #2843/#9943 is a PCI I/O processor with 64 MB of memory that drives PCI
IOA adapters on the Models 820, 830, 840 and 890 on the #5075 PCI Expansion
Tower when attached to the Model 820, the #5074 PCI Expansion Tower, the
#5079 1.8 M I/O Tower, and the #5078 PCI Expansion Unit.
The #2843 is supported on the Models 810, 825, 870, and 890, and the #5088,
#5094, #5095 and #5294.
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 the Models 830 and 840 a PCI IOP is not embedded on the backplane, but a
#9943 Base PCI IOP is included with the system. Up to four #2843 PCI IOPs
may be added in the system unit of the Models 830 and 840. On the #5074 PCI
Expansion Tower, a PCI IOP is not embedded, but a #9943 Base PCI IOP is
included. Up to five #2843 PCI IOPs may be added to a #5074. Up to six #2843
PCI IOPs may be added to a #5078.
On the #5079 1.8 M I/O Tower, a PCI IOP is not embedded, but two #9943 Base
PCI IOP are included. Up to 10 #2843 PCI IOPs may be added to the #5079.
Note: The #9943 may only be on initial system orders or on Miscellaneous
Equipment Specification (MES) orders that add #5074, #5078, or #5079
towers to an installed system. The maximum number of #9943s installed on a
system is one in the system unit, plus one in each #5074 and two in each
#5079.
These IOAs are supported (driven) by the embedded PCI IOP (Model 820) and
the #2843/#9943 Base PCI IOP:
#2742 Two-Line WAN IOA
#2743 1 Gbps PCI Ethernet IOA
#2744 PCI 100 Mbps Token Ring IOA
#2749 PCI Ultra Magnetic Media Controller
#2757 PCI-X Ultra RAID Disk Controller
#2760 PCI 1 Gbps Ethernet UTP Adapter
#2763 PCI RAID Disk Unit Controller (
November 2003)
#2765 PCI Fibre Channel Tape Controller
#2766 PCI Fibre Channel Disk Controller
#2768 PCI Magnetic Media Controller
#2772/#2773 PCI Dual WAN/Modem IOA
