The Model 820 does not include an internal battery. We recommend that you use an
external UPS to protect the system unit and any external components against utility
power outages. Continuously Powered Mainstore (CPM) is not supported on the Model
820. An external UPS, combined with abnormal IPL improvements in OS/400, can
provide an equivalent level of power protection and recovery in the event of power failure.
The Model 820 server initial installation is Customer Setup (CSU). Model upgrades are
performed by IBM service representatives.
OS/400 V4R5 is required to support the 820 servers.

Card Technology

With the implementation of new PCI technologies, the Model 820 provides more flexibility in
the placement of IOPs and IOAs. This results in more efficient use of card slots, which may
potentially result 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 particular areas was required, a 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 AS/400 system is required.
The following 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 dialup or Shorthold Mode WAN
