Card Technology

With the implementation of new PCI technologies, the Model 840 provides more flexibility in
the placement of IOPs and IOAs. This results in more efficient use of card slots, potentially
resulting in a lower cost of implementation.
Prior AS/400 models required input/output processors (IOPs) to be in specific slots in the
system and expansion towers. If high performance in a particular area was required, a single
input/output adapter (IOA) may have been assigned to a single IOP. This resulted in
unassigned slots in the tower, leaving valuable slots empty.
This PCI I/O structure enables customer setup of selected features of the Model 840. It also
enables Hot Plug PCI for adding and replacing hardware without taking the server down. A
full understanding of configuration rules associated with the various I/O features of the 840
system is required.
The 840 processors support four 32-bit and ten 32/64-bit PCI slots.
The following functions do not have equivalent function PCI cards for the Model 840:
• ASCII Adapter
• V.25 Autocall cable
• Select standby mode
• X.21 switched WAN dialup or Shorthold Mode WAN
• Asynchronous communication speeds of less than 300 bps
• Data Rate Select signal on the EIA 232/V.24 interface. This function is used by some
older 2400 bps modems to reduce the speed to 1200 bps.
