Removing the Processor Air Duct
The processor air duct is black plastic with rubber grommets that reduce vibration. It
must be removed to access the processors and the memory DIMMs. The air duct is
required to ensure proper air flow within the chassis, so be sure that it is in place
again before re-installing the back cover.
To remove the processor air duct:
1. Power down the server and remove all peripheral devices and the power cord(s)
2. Remove the back chassis cover. For instructions, see “Removing the Chassis Covers”.
3. Remove the riser card assembly. For instructions, see “Removing the Riser Card
Assembly”.
4. Slide the air duct back to free it from the fan bracket and towards the center of
the chassis to free it from the edge. (Figure 14, “A”)
5. Lift the air duct straight up to remove it.
