Chapter 8. IBM iSeries towers schematics
This chapter identifies the system diagrams for the towers that are supported by the IBM
iSeries servers and the power and packaging features for those towers.
Migration towers are the result of an upgrade from an AS/400e 600, 620, 640, 650, 720, 730,
740, or Sxx model to an iSeries 820, 830, or 840 model. All the I/O and disk units in the
former system unit and any attached towers remain accessible to the upgraded system with
the connection of the migration tower to the high-speed link (HSL) loop. iSeries Models 820,
830, and 840 support upgrades of existing system units and expansion towers from Models
720, 730, and 740 by converting the system tower of those systems into either a #5033,
#5034, or #5035 Migration Tower I or a #5077 Migration Tower II. Migration towers are not
supported by the IBM eServer iSeries 270 models.
Refer to 13.1, “HSL cables” on page 462 for information about HSL cables.
