Precautions Specific to Fan Assemblies
Danger: Be careful not to accidentally insert your fingers into the fan assembly while removing
it from the chassis. The fan may still be spinning at a high speed.
Caution: Disassembling any part of the power supply and fan assembly voids the warranty and
regulatory certifications. There are no user-serviceable parts inside the power supply
and fan assembly.
Caution: Ensure that the airflow direction of the power supply unit matches that of the installed
fan assembly. The power supplies and fan assemblies are clearly labeled with either
a green arrow with an "E", or an orange arrow with an "I."
Caution: If you do not install a module or a power supply in a slot, you must keep the slot
filler panel in place. If you run the chassis with an uncovered slot, the system will
overheat.
