Precautions specific to the power supply and fan assemblies
NOTE
The two power supply and fan assemblies concurrently installed in the chassis must be of the same
type (AC), model (airflow direction), and part number. If the airflow directions are different, an error is
generated on the console.
NOTE
The power supply and fan assembly units are hot-swappable if they are replaced one at a time. They
are identical and fit into either slot.
NOTE
The device can operate all the ports with one power supply and fan assembly unit if you do not require
redundancy.
The device fans are fixed inside the combined power supply and fan assemblies to provide necessary
airflow to cool the whole system. There are three fans located in each unit. The system software sets
fan speed and measures fan speed through the tachometer interface.
Precautions specific to the power supply and fan assemblies
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 unit matches that of the installed fan tray.
The power supplies and fan trays 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.
