Precautions Specific to Power Supplies

Danger: Make sure that the power source circuits are properly grounded, then use the power cord supplied with the device to connect it to the power source.
Danger: If the installation requires a different power cord than the one supplied with the device, make sure you use a power cord displaying the mark of the safety agency that defines the regulations for power cords in your country. The mark is your assurance that the power cord can be used safely with the device.
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 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.
Caution: Use a UL listed or CSA Certified DC power source to connect to a DC PSU.
