The DC power supplies in QFX10002 models (see Figure 1) are hot-removable and hot-insertable field-replaceable units (FRUs) that install without powering off the device or disrupting the switching function. The two 1600-W power supplies in a QFX10002-36Q are installed at the factory and supply 1200 W of power to the chassis. Likewise, the four 1600-W power supplies in a QFX10002-72Q switch are installed at the factory and supply 2400 W of power to the chassis.
A QFX10002 has 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 Understanding QFX10002 Hardware Redundancy. Each power supply provides 12-VDC output with a standby voltage of 12 VDC.
