The following features still need to be added to the system:
• One #2843 PCI IOPs
• #5074 PCI Expansion Tower with base #9943 IOP
• Three #4746 PCI Twinax Workstation IOAs (provides attachment for Twinax device
addresses)
• One #4748 PCI RAID Disk Unit Controllers (provides attachment Disk Units and
RAID-5 capability)
• One #4838 PCI 100/10 Mbps Ethernet IOAs (provides attachment to 100 Mbps
Ethernet segment)
At this point, the Model 820 processor cannot support any more cards so the remaining cards
have to be placed in the #5074 Expansion Tower. Since a separate IOP is needed for the
#4838 and there is a limit to the number of IOAs in the first Multi-Adapter Bridge in the #5074,
the #4838 will be placed on the #9943 Base IOP in the #5074. As demonstrated earlier, there
is more than enough capacity on the #2843/#9943 for the #4838, the complete validation
procedure will not be used. After installation, the configuration will appear as shown in the
following figure.
