FIGURE 4-11 Removing the CPU From the Socket
6. Install the new CPU and heatsink:
Note – Mixing CPU speeds or mixing dual-core CPUs with single-core CPUs is not
supported. Use two identical CPUs in your server.
a. Unpack the new CPU and heatsink.
b. Ensure that the CPU socket release lever is in the fully open, vertical position.
c. Align the CPU in the socket as shown in FIGURE 4-11 .
Note – Align the triangle that is printed on one corner of the CPU with the tiny
triangle that is imprinted on the CPU socket, as shown in the red circle in
FIGURE 4-11 .
Caution – The pins on the CPU are very fragile. If the CPU is correctly aligned, it
will enter the CPU socket with little or no resistance. If you feel more than minimal
resistance, stop and recheck the alignment. Forcing a misaligned CPU into the CPU
socket could damage both devices.
d. Gently insert the CPU pins into the socket.
e. When the CPU is fully seated in the socket, pivot the release lever down and
into the locked position, at the side of the socket.
