AS/400e server 830
168 AS/400e System Handbook
• #3062: 128 MB Main Storage DIMM (64 Mb technology)
• #3064: 256 MB Main Storage DIMM (128 Mb technology)
• #3065: 512 MB Main Storage DIMM (128 Mb technology)
For processors #2400 and #2402:
• For new systems without #2881 Main Storage Expansion, DIMMs are added in octals
on the base Main Storage card.
• For new systems with #2881 Main Storage Expansion, DIMMs are added in octals and
“spread” across the Base Main Storage card (CCIN 2881) and the #2881 Main Storage
Expansion.
• For MES orders without #2881 Main Storage Expansion, DIMMs are added in octals
on the Base Main Storage card (CCIN 2881).
• For MES orders with #2881 Main Storage Expansion, DIMMs are added in octals and
“spread” across the Base Main Storage card and the #2881 Main Storage Expansion.
• If a #2881 Main Storage Expansion is added on an MES order, it is not required that
theDIMMs(inoctals)are“spread” equally between the Base Main Storage card
(CCIN 2881) and the #2881 Main Storage Expansion.
For processor #2403:
Both the Base Main Storage card (CCIN 2881) and the #2881 Main storage Expansion are
required. For both new builds and MES orders, the DIMMS (in octals) are “spread” across the
base Main Storage card and the #2881 Main Storage Expansion.
Power and Packaging
The Model 830 includes an internal battery that is automatically activated in the event of a
utility power loss. The battery provides full operating power for a short time to all components
within the system unit, but not to any external components. This can allow the system to run
uninterrupted for a short time (30 seconds or less). For longer power outages, the system will
use the battery to attempt an orderly shutdown to avoid losing data in main storage that is not
written to disk. An external UPS is recommended to protect the system unit and any external
components against utility power outages. Continuously Powered Mainstore (CPM) is not
supported on the Model 830. An external UPS can allow the system to run uninterrupted for
longer than thirty seconds when utility power is lost. It can also maintain power long enough
to ensure that the system successfully completes a shutdown to avoid losing data.
