iSeries Model 820

single input/output adapter (IOA) may have been assigned to a single IOP. This resulted in

unassigned slots in the tower, and valuable slots were left vacant.

This PCI I/O structure enables customer setup of the Model 820 and selected features on all

models. 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 iSeries server is required.

These functions do not have equivalent function PCI cards for the Model 820:

• ASCII Adapter

• V.25 Autocall cable

• Select standby mode

• X.21 switched WAN dial-up 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.

• LPDA-1 (Link Problem Determination Aids). This is a diagnostic function supported by

some (primarily older IBM) modems.

• V.54 local and remote loopback (diagnostics functions supported by some modems)

The fundamental bus architecture of the iSeries server is unchanged when using PCI

adapters. The AS/400e IOP continues to off load the main processor; isolate the host from

the adapter and network errors; and manage, configure, and service the adapters. PCI

architecture offers advantages in flexibility over non-iSeries or non-AS/400e server
