POWER7 system and the "Deferred Level"set to support the POWER5 system.
Connect the 731 O-CR3 with the "Deferred Level"password. B. Consult the HMC / Firmware Supported Combinations chart to obtain the proper firmware/HMC
code levelsimplementthe firmware updates on the POWER5 and 7310-CR3 HMC first,
Connectthe 7310-CR3 to the POWER7 system. C. Connect the new HMC to the POWER7 system and to the LAN.
Use the "Transmit Service Information"dialog on the new HMC to update the 7310-CR3 with the
new HMC code and firmware for the FSP.
Update the firmware on the POWER5 system and connect the new HMC. D. Upgrade the POWER5 system firmware to the same fix pack level that the POWER7 system is
running. Upgrade the 7310-CR3 to the latest version of HMC code.
