attached peripherals.
Cooling Shroud
The system provides a cooling shroud that directs airflow from the cooling
fans over the system processor(s) and memory module(s).
WARNING:
The memory modules are hot to the touch for some time after the
system has been powered down. Allow the memory modules to cool before
handling them.
CAUTION:
Many repairs may only be done by a certified service technician. You
should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not covered
by your warranty. Read and follow the safety instructions that came with the
product.
CAUTION:
Never operate your system with the cooling shroud removed.
Overheating of the system can develop quickly resulting in a shutdown of the
system and the loss of data.
Removing the Cooling Shroud
1 Turn off the system, including any attached peripherals, and disconnect
the system from the electrical outlet.
2 Open the system. See "Opening the System."
3 Use the lift handles on the cooling shroud to lift the shroud out of the
system. See Figure 3-13.
