xSeries 445 Type 8870: Option Installation Guide
Important: When installing Intel Xeon DP microprocessors, you must install
them in the following order: socket 1 then socket 4. When installing Intel Xeon
MP microprocessors, you must install them in the following order: sockets 1, 2,
3, and then 4.
a. Remove the protective label from the microprocessor socket.
b. Rotate the locking lever on the microprocessor socket from its closed and
locked position until it stops or clicks in the fully open position
(approximately 135° angle), as shown.
c. Align the triangle icon on the microprocessor with the triangle icon on the
socket and press the microprocessor gently into the socket.
Attention: Make sure that the microprocessor is aligned correctly before
you proceed. To avoid bending the pins on the microprocessor, do not use
excessive force when pressing it into the socket.
d. Close the locking lever to secure the microprocessor.
a. Remove the heat sink from its package and detach the protective cover
from the bottom of the heat sink
Attention: Do not disturb or contaminate the heat-conducting grease on
the bottom of the new heat sink. Doing so damages its heat-conducting
capability and exposes the new microprocessor to overheating.
