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.
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 shut down,
which in turn shuts down the device without any warning message.
Identifying the Airflow Direction
The power supply and fan assemblies are identified 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.
•
Port-side air intake
•
Nonport-side air exhaust
•
Front-to-back (port-side to nonport-side) airflow
•
Part numbers ending with -F
Power Supply and Fan Assembly Fault Indicators
Use one of the following fault indicators to determine the status of the power supply and fan assemblies:
