CMOD Components
CMODs include the following processor (CPU) and DIMM memory components:
- 
                     
                     
Processor Heatsink Module (PHM) assembly includes heatsink, processor, thermal interface material (TIM), and carrier.
 - 
                     
                     
12 DIMM slots arranged in two groups of six
 - 
                     
                     
Fault Remind Test Circuit, which helps you locate failed DIMMs and verify a failed CPU
