AS/400e server 270
• For placement, an initial pair of memory DIMMs is allowed (in slot A and slot B) without
quads. After that, all DIMMs must be plugged in quads starting from the outer four
corners going toward the center (A, B, C, D, then E, F, G, H, and so on). Using the
same feature code number within a quad is required. Mixing quad “groups” on the
same riser card is also allowed (including mixing stacked (#3025) and unstacked
(#3024) memory technology).
Power and Packaging
The Model 270 does not include an internal battery. An external UPS is recommended to
protect the system unit and any external components against utility power outages. The
AS/400 CPM/UPS Models 9910-080, 9910-140, and 9910-180, which were previously used
with the 9406 Model 170, can also be used with the Model 270. An external UPS, combined
with abnormal IPL improvements in OS/400, can provide an equivalent level of power
protection and fast recovery in the event of power failure. The Continuously Powered Main
store (CPM) is not supported on the Model 270.
The supported power and packaging features for the Model 270 are:
• #7002 HSL Enabler
– #7002 is a feature High Speed Link (HSL) internal flex cable, which enables
connection to a #5075 PCI Expansion Tower.
– Can be ordered on the Model 270 with processor #2248, #2250, and #2422 only.
– This cable connects the processor with a right angle bus connector to the back of the
machine. Two HSL cables (#14XX) are required to connect the CEC to the expansion
tower.
Note: On processor upgrades from #2248, #2250, #2422 to #2252, #2253, #2423, #2424
RPO, remove the #7002. These processor upgrade paths are “roll-in/roll-out” system
upgrades. The new system unit comes standard with an internal flex cable.
• #7104 System Unit Expansion
– The #7104 is a feature system unit expansion that allows up to an additional 12 disk
units to be added to the Model 270. The #7104 has no PCI card slots and no
removable media slots.
– The #7104 comes with support for six disk units standard and requires a #7123 when
installing over six disk units.
– The #7104 disk units are driven by a disk unit controller located in the CEC.
