3-24 Sun Fire X4100/X4100 M2 and X4200/X4200 M2 Servers Service Manual • August 2009
Note – If you have a Sun Fire X4200 server, see “Replacing a CPU and Heatsink (Sun
Fire X4100 and X4200 Servers)” on page 3-17.
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.
Note – Software Release 2.0 or later is required to support AMD Opteron Quad-Core
CPUs. Before replacing a dual-core CPU with a quad-core CPU, check the version
strings against those documented in the Sun Fire X4100 M2/X4200 M2 Servers Release
Notes. If the existing firmware is not for Software Release 2.0 or later, perform the
necessary upgrade before proceeding.
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.
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 3.8 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 3-16. There is a
fault LED on the motherboard for each CPU (see
FIGURE 3-16 for the LED location):
■ LED is off: CPU is OK.
■ LED is lit (amber): CPU has encountered a voltage or heat error condition.
Note – If the power cords are disconnected, the CPU fault LEDs can be lit for several
minutes by pressing switch SW2 on the motherboard.
