Field Replaceable Unit (FRU) Procedures

Installing a New CPU and Heatsink
Installing a new processor and heatsink is an extra-cost option.
Safety Cautions
Electrostatic discharge (ESD) can damage server board components. Perform CPU replacement procedures only at an
ESD workstation. If no such station is available, you can provide some ESD protection by wearing an antistatic wrist
strap and attaching it to a metal part of the computer chassis.
To install a new processor, follow these steps:
1. Following the instructions packaged with your boxed processor, prepare the new processor for installation.
2. Open the socket handle (make sure it is in the full upright position) and remove the terminator (if adding a
processor to an existing one processor system).
3. Aligning the pins and notches of the new processor with the socket, insert the processor into the socket.
4. Verify the processor sits flush and level on the socket.
5. Lower the locking bar completely until it locks (see Figure 76).
!
Caution : The procedure below is for the attention of qualified service engineers only. Before
touching or replacing any component inside the LX50 server, disconnect all external cables
and follow the instructions in “Safety: Before You Remove the Cover” on page 5-2 and
“Removing and Replacing the Cover” on page 5-3. Always place the server on a grounded
ESD pad and wear a properly grounded antistatic wrist strap.
!
Caution: Pressing the power button does not turn off power to this board. Disconnect the
server board from its power source and from any telecommunications links, networks, or
modems before doing any of the procedures described in this guide. Failure to do this can
result in personal injury or equipment damage. Some circuitry on the server board may
continue to operate even though front panel power button is off.
!
Caution: You should not allow any surface that has thermal interface material to come in
contact with any other surface, as surface contamination may occur.
!
Caution: Lower the locking bar slowly and make sure that the socket handle is engaged on the
locking tab on the side of the socket.
