Attention:
v A startup (boot) processor must always be installed in microprocessor connector
1 on the system board.
v To ensure correct server operation when you install an additional microprocessor,
use microprocessors that have the same cache size and type, and the same
clock speed. Microprocessor internal and external clock frequencies must be
identical.
To
install an additional microprocessor, complete the following steps:
1. Read the safety information that begins on page v and “Installation guidelines”
on page 7.
2. Turn off the server and peripheral devices, and disconnect the power cords and
all external cables.
Attention: In a dc power environment, only trained service personnel other
than Lenovo service technicians are authorized to connect or disconnect power
to the dc power supply. See the documentation that comes with each dc power
supply.
