Removing Or Installing A Cpu Module - Sun Microsystems Sun Enterprise 450 Guia De Instalacion

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 "Setting the Main
Logic Board Jumpers" on page 6 in this guide, and verify that the jumper setting is
correct for the speed of the CPU module(s) you are installing. Serious system
damage can result if the main logic board clock mode jumpers are set incorrectly.
If you need to know your system's power consumption, read the section "System
Power Requirements Worksheet" on page 5 in this guide, and then consult the
section "How to Determine System Power Requirements" in the Ultra Enterprise 450
Server Owner's Guide.
The 480-MHz CPU modules require an air guide for proper cooling. This air guide is
installed on the 501-5673 main logic board. You must remove the air guide to access
the CPU modules, and replace the air guide before restarting the system. For
instructions on removing and replacing the air guide, see "Removing and Replacing
the CPU Air Guide" on page 8.
To remove or install CPU modules into 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.
Before you install the fourth CPU module into the top CPU slot (CPU-A1), remove
the blank baffle, if installed, from the connector (J0101). Grasp the blank baffle by the
front handle and pull it out from the CPU slot.
