Sun Enterprise 450 Server Product Notes en-5
Configuring the CPU Modules
Before configuring the CPU module(s), determine if your system will support the
power requirements of the new configuration. Review the “System Power
Requirements Worksheet” on page 16 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.”
Removing or Installing a CPU Module
Before removing or installing CPU modules, read the section “About CPU Modules”
in the Ultra Enterprise 450 Server Owner’s Guide.
Caution –
Before you install any CPU module, read the section “Main Logic Board
Jumpers” on page 12, and verify that the jumper setting is correct for the speed of
the CPU module you are installing. Serious system damage can result if your main
logic board clock mode jumper is set incorrectly.
To remove or install CPU modules in the Sun Enterprise 450 server, follow the
instructions in the sections “How to Remove a CPU Module” and “How to Install a
CPU Module” in the Ultra Enterprise 450 Server Owner’s Guide.
Note –
The 480-MHz CPU module requires a CPU air guide. For instructions on
removing and installing the CPU air guide, see “Removing and Replacing the CPU
Air Guide” on page 6.
