Upgrades to iSeries 8xx Servers
Upgrades to iSeries 8xx Servers
Upgrades to the 8xx servers can involve a housing change from a CEC to a tower. In some
cases, an existing system CEC (on a 7xx system, for example) is converted into an 8xx I/O
tower. All towers attached to the existing system CEC remain untouched.
Customers with AS/400e 7xx servers can upgrade to the iSeries 8xx models. This excludes
the SB1 model. CISC models and RISC servers 6xx models and prior cannot be upgraded to
the 8xx models.
The redbook AS/400e to iSeries 400 Migration , SG24-6055, provides guidance for upgrading
to the iSeries server 8xx models.
No upgrades are offered into the Model 270 from any earlier models, nor can the Model 270
be upgraded into the 8xx models.
For software considerations, refer to “Supported Upgrade Paths” on page 515 and “Current
Release to Previous Release Support” on page 516.
Interactive Performance Reduction Option for 8xx and 7xx Servers
In some cases, a supported upgrade path involves a reduction in Interactive CPW ratings.
7xx customers who do not want to keep their current interactive card may reduce their
interactive capacity by one level when upgrading to a new 8xx server. This can lower the price
paid for the upgrade.
For example, a customer with 1050 Interactive CPW (Interactive Feature #1510) upgrading to
an 8xx server can choose a model with a lower Interactive CPW level (for example, 560).
Customers choosing this reduction option will be required to repurchase (at full price) any
additional Interactive CPW in the future.
Customers are encouraged to review current Interactive CPW utilization with PM/400,
Management Central, or other AS/400 Performance Tools prior to using this interactive
performance reduction option.
