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. 229
