8.3 Migration towers schematics
Migration towers are used to migrate existing PCI and SPD cards, existing disk units, and
existing removable media devices. Migration towers are HSL attached but contain SPD
buses only. 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 a migration tower to the HSL loop.
For details about hardware supported in migration towers, see Chapter 5, “IBM AS/400e 720,
730, and 740 models” on page 129, or AS/400e RISC System Builder, REDP-0342.
8.3.1 #5033, #5034, and #5035 Migration Tower I
The #5033 is a converted AS/400e 600/S10 system unit/CEC tower.
The #5034 is a converted AS/400e 620, S20, or 720 system unit tower (with 10 possible
internal system unit disk unit positions) and any existing #5064 or #9364 System Unit
Expansions.
The #5035 is a converted 620, S20, or 720 system unit/CEC tower (with 15 possible internal
system unit disk unit positions), and any existing #5064 or #9364 System Unit Expansions.
With OS/400 V5R1 and later, a #5035 Migration Tower I can be obtained by way of RPQ
847120. RPQ 847120 was withdrawn from marketing on 17 September 2002.
The #5033 Migration Tower I, #5034 Migration Tower I, and #5035 Migration Tower I
schematics are not shown in this publication. The layout of the #5033 is equivalent to the
Model 600 system unit without processor cards. Refer to AS/400e RISC System Builder,
REDP-0342, for Model 600 system unit schematics that are equivalent to the #5033 Migration
Tower I.
The layouts of the #5034 and #5035 are equivalent to the Model 720 system unit without
processor cards. Refer to 5.5.1, “Model 720 #2061 processor” on page 134, and 5.5.2,
“Model 720 #2062, #2063, #2064 processors” on page 135, for equivalent #5034 Migration
Tower I and #5035 Migration Tower I drawings.
8.3.2 #5077 Migration Tower II
The #5077 Migration Tower II is HSL attached but contains SPD buses only. The #5077 is a
feature I/O tower that supports SPD I/O cards and attaches SPD expansion towers and
#5065/#5066 PCI Expansion Towers.
When upgrading to a Model 830 or 840 from a Model 640, S30, or 730, the #5077 is a
manufactured unit. It is shipped without a base CD-ROM and without a base optical link card
(CCIN 2696). If upgrading to a Model 830 or 840 from a Model 640, S30, or 730 without a
#5055 Storage Expansion Unit installed, by default, the #5077 is shipped with a #9057
Storage Expansion Unit. The #9057 can be removed from the order. If upgrading from a
Model 640, S30, or 730 with the #5055 installed, a #5055 to #9057 conversion is performed.
When upgrading to a Model 840 from a Model 650, S40, or 740, the #9251 Base I/O Tower
on these models is converted to a #5077. When upgrading to a Model 840 from a Model 820
or 830 with the #5034 or #5035 Migration Tower I with SPD cards or SPD towers attached,
the #5077 is a manufactured unit. It is shipped without a base CD-ROM and with a base
optical link card (CCIN 2696).
