6 Processors
V CAUTION!
Observe the safety instructions in the chapter āSafety notesā on page 15.
V CAUTION!
Processors are modules which can react extremely sensitively to electro-
static discharges and which must therefore always be handled with care. 
After a processor 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 processor over a surface.
6.1 Installing a second processor
The system board can be upgraded with a second processor. The upgrade kit 
consists of a processor, and a heat sink.
V CAUTION!
Only processors of the same type may be used on the system board. The 
second processor must have the same clock frequency and the same 
cache as the first processor. For dual operation, use a suitable multipro-
cessor operating system.
