of these features. It should be used to ensure a valid configuration. The use of performance tools may also help in optimizing a configuration to match a specific set of requirements.

Note: When ordering a model upgrade from a mixed-mode server (S20, S30, S40) to AS/400 7xx servers, an Interactive Specify code must be on the model Sxx inventory record prior to ordering the model upgrade. The configurator will generate a Record Purpose Only (RPO) order to add a zero-priced Interactive Specify code to the installed mixed-mode server prior to the upgrade. This is a required step.

Sxx Interactive Specify codes that the configurator will add:

vModel S20 Interactive Specify codes

–1490

–1492

vModel S30 Interactive Specify codes

–1492

–1493

–1494

vModel S40 Interactive Specify codes

–1495

–1496

Migrating from a 5xx to an 8xx

When migrating SPD expansion units from an AS/400 Model 5xx or from any unsupported path to an iSeries Model 8xx, the order must have a migration expansion unit included.

IBM does not provide a pre-planned or pre-programmed upgrade from a Model 5xx to a Model 8xx. The user who wants to move I/O to 8xx hardware will have to analyze their current configuration and determine what will and will not move and plan the sequence of actions to make it happen. Here are some general considerations:

vSPD I/O expansion unit can not be directly attached to an 8xx. A migration expansion unit with SPD capability is required. If you have a Model 830 or 840 and do not have a migration expansion unit yet, a migration expansion unit (migration expansion unit II), FC #5077 (and perhaps an FC #5057 expansion unit), should be ordered. IBM does not offer an option to order a migration expansion unit (migration expansion unit I) which could attach to an 820.

vSPD IOPs can not be inserted into an 8xx except via SPD slots in a migration expansion unit or in SPD I/O expansion unit attached via a migration expansion unit.

vNot all I/O is supported by V4R5 or V5R1 on an 8xx. There were several older disk units, tape drives, IOPs, and so forth, which were no longer supported as of V4R1.

vThe I/O expansion unit, on a Model 500 or 510 only has a 266 Mbps Optical bus Adapter which is too slow for the migration expansion unit to support. Using the S40388 RPQ, the expansion unit can be converted to a faster I/O expansion unit with a 1063 Mbps Optical Bus Adapter.

vSince V4R5, the only type of PC console that an 8xx system supports is Operations Console.
