Powering Off a QFX3600 Device

NOTE: Use the following procedure to turn off power on a QFX3600 device that is in standalone
mode, a member in a QFX Virtual Chassis, or a leaf device in a Virtual Chassis Fabric. QFX3600
devices that are Node devices in a QFabric system running OS Junos release 14.1 or later must
use a different procedure and CLI to ensure there is no traffic loss. See Powering Off an Existing
QFabric Node Device. To remove power from a QFX3600-I Interconnect device, see Adding or
Replacing an Interconnect Device in a QFX3000-M QFabric System.
