Model 55x or OpenPower® 720 system processor assembly

You might need to install, remove, or replace the system processor assembly. This section includes procedures so that you can perform these tasks.

Attention: Adding the second processor assembly requires that the system be powered by 220 V ac. If your system is not currently installed with 220 V ac input, contact your IBM® reseller to obtain the correct power features.
Restriction: Different processor types cannot be mixed in the same system.
