using a right-angle bus connector to the back of the machine. Two #14xx HSL cables are required to connect the system
unit to the expansion tower.
The marketing configurator removes for Record Purpose Only (RPO) the #7102 from the inventory records on processor
upgrades from #2248, #2250, #2422, or #2431 to other processor features.

#7104 #7104 System Unit Expansion
The #7104 is a feature system expansion unit that allows up to an additional 12 disk units to be added to the Model 270.
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 card enclosure. The #7104 requires a separate line cord
from the system unit. One #14xx power cord must be specified (geography dependent). When the Model 270 and attached
#7104 are mounted in a #0551 iSeries Rack, #1422 PDU Line Cord might be specified if a PDU is installed in the #0551
iSeries Rack.
