After inserting a power cable and confirming the green System Status LED
light is on, make sure that the Fan Status LED shows green.
If the Fan Status LED is not green, unplug the power connection and check
that the fan module is inserted properly and that the mating connector of
the fan unit is free of any dirt and/or obstacles. If no obstacles were found
and the problem persists, call your Penguin Computing representative for
assistance.
Risk of electric shock and energy hazard.
The two power supply units are
independent.
Disconnect all power supplies to ensure a powered down state inside of
the switch platform.

FRU Replacements
The following information does not apply to the Arctica 1600cs series. The
Arctica 1600cs systems include two non-replaceable power supply units
and four non-replaceable fan units.
Power Supply
Arctica systems that are equipped with two replaceable power supply units work in a redundant
configuration. Either unit may be extracted without bringing down the system.
Ensure that the power supply unit that you are NOT replacing is showing
all green, for both the power supply unit and System Status LEDs.
Power supply units have directional air flows similar to the fan module.
The fan module airflow must coincide with the airflow of all of the power
supply units. If the power supply unit airflow direction is different from the
fan module airflow direction, the system’s internal temperature will be
affected.
For power supply unit air flow direction, refer to
Fans.
