This specify code is only valid when two iSeries 270 servers are ordered at the same
time for simultaneous delivery. One system must specify #0551 and #0121, while the
second system specifies #0122.
The two 270 servers combined require 30 EIA units in the lower part of the #0551
rack. This leaves six EIA units available at the top of the rack for additional devices.
Each iSeries server 270 is an independent system.
Feature #7104 System Unit Expansion is required in order for an iSeries server 270 to
mount in a #0551 rack.
The 270 server may be powered by the Power Distribution Unit (PDU), if installed,

line cord must be ordered.
Note: Two line cords are required.
Certain upgrade paths are not supported when an iSeries server 270 is installed in a
