DC Power Grounding Requirements and Warning
This topic applies to hardware devices in the EX Series product family, which includes
EX Series switches and the XRE200 External Routing Engine.
This topic also applies to hardware devices in the QFX Series and to OCX1100 switches.
An insulated grounding conductor that is identical in size to the grounded and ungrounded
branch circuit supply conductors but is identifiable by green and yellow stripes is installed
as part of the branch circuit that supplies the device. The grounding conductor is a
separately derived system at the supply transformer or motor generator set.
WARNING: When you install the device, the ground connection must always
be made first and disconnected last.
