This topic applies to hardware devices in the EX Series product family, which includes
EX Series switches, the EX Series Redundant Power System (RPS), and the XRE200
External Routing Engine.
This topic also applies to hardware devices in the QFX Series and to OCX1100 switches.
WARNING: Certain ports on the device are designed for use as intrabuilding
(within-the-building) interfaces only (Type 2 or Type 4 ports as described in
GR-1089-CORE) and require isolation from the exposed outside plant (OSP)
cabling. To comply with NEBS requirements and protect against lightning
surges and commercial power disturbances, the intrabuilding ports must not
be metallically connected to interfaces that connect to the OSP or its wiring.
The intrabuilding ports on the device are suitable for connection to
intrabuilding or unexposed wiring or cabling only. The addition of primary
protectors is not sufficient protection for connecting these interfaces
metallically to OSP wiring.
