iSeries Model 820
The supported power and packaging features are as follows:
• #7127 DASD Expansion Unit
– The #7127 is a concurrent maintenance DASD 6 Position expansion feature, which
may be ordered to support an additional six disk units (for a total of 12) in the Model
820 system unit/CEC.
– Prerequisite: #5157 Feature Power Supply.
• #5102 Dual Line Cord - 820 CEC
– The #5102 provides dual line cord capability for the model 820 system unit. Two
#14XX line cords are required on the Model 820 when this feature is ordered initially
or as an upgrade to a Model 820. When ordering #5102 alone as an MES, an
additional #14XX line cord is required, for a total of two line cords on the system unit.
– Prerequisites: #5155 Redundant Power and Cooling, #5157 Feature Power Supply,
and #9002 Dual Line Cord Enabler.
– OS/400 V5R1 and supporting PTFs are required. Refer to Informational APAR II12950

• #5157 Feature Power Supply
– The #5157 adds an additional 575 Watt power supply to the Model 820.
– The #5157 is the default for all processors but may be removed from the order.
Note: Redundant power on the model 820 CEC requires both the #5155 and #5157
features. If the #5155 is removed, the #5157 should be removed. The exception is to
leave the #5157 due to the presence of a #7127 DASD Expansion Unit.
– The #5157 is required when a #7127 Disk unit cage is added to a Model 820 and is
required when a #5155 Redundant Power and Cooling feature is added to a Model
820.
• #5155 Redundant Power and Cooling
– The #5155 adds an additional 575 Watt power supply for redundancy and additional
cooling fans to the Model 820.
– The #5155 is the default for all processors
– Prerequisite: #5157 Feature Power Supply
• #9002 Dual Line Cord Enabler
– The #9002 is a specify code that is added to all 820 systems ordered (initial orders or
model upgrades into the 820) on or after the V5R1 announcement, regardless of
operating system level ordered. This specify code is used to determine that the 820
