General Electrical Safety Guidelines and Warnings for EX Series Switches

WARNING: Certain ports on the switch are designed for use as intrabuilding
(within-the-building) interfaces only (Type 2 or Type 4 ports as described in

GR-1089-CORE

, Issue 4) 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 switch 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.
