1.8 Build to Order
You can perform a Build to Order (also called a la carte) configuration using the IBM
Configurator for e-business (e-config), where you specify each configuration feature that you
want on the system.
This is the only configuration method for the IBM Power 770 and Power 780 servers.
1.9 IBM Editions
IBM Edition offerings are not available for the IBM Power 770 and Power 780 servers.
1.10 Model upgrade
You can upgrade the 9117-MMA with IBM POWER6 or POWER6+™ processors to the IBM
Power 770 and Power 780 with POWER7 processors. For upgrades from POWER6 or
POWER6+ processor-based systems, IBM will install new CEC enclosures to replace the
enclosures that you currently have. Your current CEC enclosures will be returned to IBM in
exchange for the financial consideration identified under the applicable feature conversions
for each upgrade.
Clients taking advantage of the model upgrade offer from a POWER6 or POWER6+
processor-based system are required to return all components of the serialized MT-model
that were not ordered through feature codes. Any feature for which a feature conversion is
