Upgrade and Maintenance Manual 251
11.2 Upgrading to 2 CPUs configuration
V CAUTION!
– CPUs are modules which are extremely sensitive to electrostatic
discharges and therefore must always be handled with care. After a
CPU has been removed from its protective sleeve or from its socket,
place it with its smooth side down on a non-conducting, antistatic
surface. Never push a CPU over a surface.
– Only CPUs of the same type may be used on the system board. That
means the number of the internal CPU cores as well as the primary
clock and the QPI frequency have to be the same.
– For dual operation, use a suitable multiprocessor operating system.
