General Electrical Safety Guidelines and Warnings for J-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.
CAUTION: Before removing or installing components of a switch, attach an
ESD strap to an ESD point and place the other end of the strap around your
bare wrist. Failure to use an ESD strap could result in damage to the switch.
• Install the J-EX Series switch in compliance with the following local, national, and
international electrical codes:
•
United States—National Fire Protection Association (NFPA 70), United States
National Electrical Code.
• Other countries—International Electromechanical Commission (IEC) 60364, Part 1
through Part 7.
