3.12.2 Replacing a CPU and Heatsink (Sun Fire X4100
and X4200 Servers)
Note – If you have a Sun Fire X4200 M2 server, see “Replacing a CPU and Heatsink
(Sun Fire X4100 M2/X4200 M2 Servers)” on page 3-23.
Note – This component is an FRU and should be replaced only by qualified service
technicians. Contact your Sun Service representative for assistance.
Supported components and their part numbers are subject to change over time. For
the most up-to-date list of replaceable components for these servers, refer to:

1. Click the name and model of your server.
2. On the product page that opens for the server, click Full Components List to
view a list of components.
Use the following procedure to replace the CPU and heatsink.
Caution – Some AMD CPUs are released as special editions, which might differ in
wattage from non-special edition versions of the CPU. Do not mix special edition
CPUs with non-special edition versions. Always make sure that all CPUs in the
server have the same part number.
1. Power off the server as described in
Section 3.4 on page 3-4.
2. If the server is in a rack, slide it far enough from the rack so that you can
remove the main cover. If you cannot safely view and access the component,
remove the server from the rack.
3. Remove the main cover as described in
Section 3.5 on page 3-6 or Section 3.8 on
page 3-10.
4. Identify which CPU and heatsink you are replacing.
The designation of the two CPUs in the server is shown in
FIGURE 3-10. There is a
fault LED on the motherboard for each CPU (see
FIGURE 3-11 for the LED location).
■ LED is off: CPU is OK.
■ LED is lit (amber): CPU has encountered a voltage or heat error condition.
