DC Power Supply in an EX4600 Switch
The power supplies in EX4600 switches (see Figure 13 on page 25) are hot-removable
and hot-insertable field-replaceable units (FRUs) that you can install in EX4600 Switches
without powering off the device or disrupting the switching function. The DC powersupply
is the same unit that is used in the Juniper Networks QFX5100 line of switches.
The DC power supply is 650 W with dual feeds for power resiliency.
