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 denes 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 certications. 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 ller panel in place. If you run the chassis with an

uncovered slot, the system will overheat.

CAUTION: Use a separate branch circuit for each power cord, which

provides redundancy in case one of the circuits fails.

CAUTION: To prevent damage to the chassis and components, never

attempt to lift the chassis using the fan or power supply handles. These

handles were not designed to support the weight of the chassis.

Note: The equipment installation must meet NEC/CEC code requirements. Consult local authorities for

regulations.

Note: If the ambient temperature is above the recommended operational limits, the power supply units

shutdown, which in turn shuts down the device without any warning message.

Identifying the airflow direction

The power supply and fan assemblies are identied by the following airflow directions:

• Intake power supply and fan assembly with an orange "I" label or without any label: Pulls air from

the nonport-side of the switch and exhausts it out the port side.

– Nonport-side air intake

– Port-side air exhaust

– Back-to-front (nonport-side to port-side)

airflow

– Part numbers ending with -R

• Exhaust power supply and fan assembly with a green "E" label: Pulls air from the port side of the

switch and exhausts it out the nonport-side.
