Configuring the CPU Modules
Before configuring the CPU module(s), determine if your system will support the
power requirements of the new configuration. Review "System Power Requirements
Worksheet" on page 5 of this guide, and see the section "How to Determine System
Power Requirements" in the Ultra Enterprise 450 Server Owner's Guide.
Caution – All CPU modules installed in a system must operate at identical clock
speeds.
Configure the UltraSPARC II CPU modules in your server according to the rules in
the section "About CPU Modules" in the 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 the next section, "Removing or Installing a CPU
Module."
