System Fans
The system includes six hot-pluggable fans to provide cooling to the system’s
interior components. Fans 1 through 4, located behind the optical drive and
SAS backplane, provide airflow over the processors and the "B" memory
modules. Fans 5 and 6, located near the power supply bays, draw air over the
"A" memory modules and into the power supplies. See Figure 3-9.
Removing a System Fan
CAUTION: Only trained service technicians are authorized to remove the system
cover and access any of the components inside the system. See your Product
Information Guide for complete information about safety precautions, working
inside the computer, and protecting against electrostatic discharge.
NOTICE: The system fans are hot-pluggable. To maintain proper cooling while the
system is on, replace only one fan at a time.
