Power supplies—The QFX5100 switch has one or two power supplies. Each power
supply provides power to all components in the switch. If two power supplies are
installed, the two power supplies provide full power redundancy to the device. If one
power supply fails or is removed, the second power supply balances the electrical load
without interruption.
To provide power redundancy to the system both power supplies must be installed.
Connect power source feed A to one power supply and power source feed B to the
second power supply.
CAUTION: Do not connect feed A and feed B to the same power supply
input terminal.
Cooling system—The 1 U models of QFX5100 line of switches have five fan modules;
the 2 U QFX5100-96S has three fan modules. If a fan module fails and is unable to
keep the QFX5100 switch within the desired temperature thresholds, chassis alarms
occur and the QFX5100 switch can shut down.
