Installing an Expansion-Card Riser
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.
1 Align the expansion-card riser with the riser guide posts on the system
board. See Figure 3-9.
2 Lower the expansion-card riser into place until the expansion-card riser
connector is fully seated.
3 If applicable, reinstall the expansion card. See "Installing an Expansion
Card" on page 89.
4 Close the system. See "Closing the System" on page 77.
5 Reconnect the system to its electrical outlet and turn the system on,
including any attached peripherals.
Cooling Shroud
The system board shroud covers the processor, heat sink, and memory
modules, and provides air flow to these components. Airflow is facilitated by
the cooling fan modules, which are positioned directly beneath the cooling
shroud. The power distribution board shroud covers the power distribution
board behind the power supply bay.
Removing the Cooling Shroud
WARNING: The memory modules and heat sink can get very hot during normal
operation. Ensure that the memory modules and heat sink have had sufficient time
to cool before you touch it.
CAUTION: Many repairs may only be done by a certified service technician. You

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
