• Uninterruptible Power Supply
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.
Refer to "Customer Install Features (CIF)" on page 429 for CIF designations of individual
features.

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.
Previous AS/400e 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
