CPU and heatsink module

The BL860c i4 Server Blade contains a processor subsystem accommodating one or two Intel Itanium
processor modules.
Each processor module consists of the following:
• CPU chip, including CPU cores, QPI links for CPU-CPU and CPU-IO Hub chip connections, and SMI
links for CPU-Memory interface chip connections
• CPU power conversion module
• Heatsink, with mechanical attachment / assembly features
WARNING:
To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system
components to cool before touching them.
CAUTION:
To prevent possible server malfunction, do not mix CPUs of different speeds or cache sizes.
CAUTION:
Removing a CPU will cause the DIMM loading rules to change. See DIMMs on page 48 and use the
loading rules for two CPUs. If you do not perform these procedures, then any memory associated
with the removed CPU will not be seen by the system.
