QFX10000 DC Power Supply LEDs
Copyright © 2019, Juniper Networks, Inc.
Each power supply connects to the combined power rail in a QFX10008 or QFX10016.
The power rail distributes the output power produced by the power supplies to different
switch components. Each AC power supply provides power to all the components in the
switch.
A DC power supply can operate with only one input DC feed connected. The Control
Board only enables the components for which sufficient power is available.
Each DC power supply has its own fan and is cooled by its own internal cooling system.
The airflow is from the front of the power supply to the back. Hot air exhausts from the
rear of the chassis.
DC power supplies are supported in only the QFX10008 and QFX10016 redundant
configuration.
