QFX5220 DC Power Supply Description
The DC power supplies in the QFX5220 (see
and
) are
hot-removable and hot-insertable field-replaceable units (FRUs) that install without powering off the device
or disrupting the switching function. The factory installed power supplies in both models are 1600-W, but
are not interchangeable. The QFX5220-128C switch has four power supplies and the QFX5220-32CD is
shipped with two power supplies. Each power supply provides 2400 W of power to the chassis.
Both power supplies have double the amount of power supplies needed to power all of the components
in the switch, which is known as 2n redundancy. When the switch has all of the power supplies installed,
the switch has full power redundancy. If a power supply fails or is removed, a second power supply balances
the electrical load without interruption. For more on redundancy features, see
. Each power supply provides 12-VDC output with a standby voltage of 12 VDC.
