CPU Module Configuration Rules

Before configuring your CPU module(s), determine if your new system will support
the power requirements of the new configuration. Review "About the System Power
Requirements Worksheet" on page 1-4 of this guide, and see the section "How to
Determine System Power Requirements" in the Ultra Enterprise 450 Server Owner's
Guide.
Caution – All CPUs installed in a system must operate at identical clock speeds.
Configure your UltraSPARC II CPU modules in your server according to the rules in
the section "About CPU Modules" in your Ultra Enterprise 450 Server Owner's Guide.
If your system has two power supplies, and you do not need a redundant power
supply, follow the instructions in "Installing a CPU Module" on page 1-6.
