Towers and Racks

To house components beyond the capability of the system unit, towers are added. Expansion

and migration towers are offered for new or migrated features respectively. Rack mounting

options are available for select systems and towers. Towers and rack mounted devices are

connected to each other using High Speed Loops (HSL).

Expansion Towers provide the iSeries servers with the ability to support additional I/O and

Disk Units. The entry iSeries server, the Model 270, supports a single tower while the Model

840 supports up to 23 towers. For information on the number and types of towers supported

by each iSeries server, see "iSeries and AS/400e Servers" on page 65.
