Removal
To remove the CPU, prepare the removal referring to steps 1 and 5 in the installation procedure
and do the reverse procedure of steps 13 to 6. Remove the heat sink by using a flat-tip
screwdriver for the fixing metal fitting.
IMPORTANT:
Do not remove any CPU unless it is failed.
Install the dust cover onto the vacant processor socket.
After the operation, heat may make the cool seat at the bottom of the
heat sink adhere to the CPU. To remove the heat sink from the CPU,
first turn the heat sink to the left and right lightly to make sure that
the heat sink can be apart from the CPU. Removing the heat sink
with it adhering to the CPU may cause the CPU and/or socket to be
defected.
Do the following procedure if a CPU is removed (or replaced).

order to clear the error information on the removed CPU (see Chapter 4).
When a CPU is replaced, select menus "Main" – "Processor Settings" to confirm that
the ID and L2 Cache of the additional CPU are defined normally (see Chapter 4).
17. Set "Reset Config Data" on the Advanced menu to "Enable." This is required to update
the hardware configuration information. See Chapter 4 for details.
