System Configuration
d. Press down the socket retention bar to lock the processor in place.
Figure 4-16: Installing a processor
Once the processor is installed, the heat sink-cooling fan assembly must be reinstalled on
top of the processor. The thermal grease you applied on the contact surfaces of the heat
sink and the processor provides the necessary thermal bonding to allow the heat sink to
draw away heat from the processor.
CAUTION:
To prevent overheating or a possible system crash, use only a heat sink-cooling
fan assembly specified for the HP ProLiant ML110 server model.
4. Reinstall the heat sink-cooling fan assembly:
a. Align then insert the heat sink-cooling fan assembly on top of the processor.
b.
If possible, slide the assembly
slightly
from side to side to help squeeze out any air
pockets trapped in the paste and to ensure even coverage.
CAUTION:
Do not to slide the assembly too much or you could smear some of the grease
onto the CPU or the motherboard, or even damage the CPU pins.
c. Press down the two heat sink retention levers to secure the assembly in place.
CAUTION:
To avoid thermal overheating ensure that both levers are firmly fastened,
providing good contact between the heat sink and processor.
d. Connect the CPU fan cable to its connector on the mainboard.
CAUTION:
Failure to connect the CPU fan cable to its connector may cause the server to
shut down with no messages displayed and possibly damage the processor.
