Chapter 1, Safety Summary

Safety Summary

This chapter provides safety considerations for operating the Cisco ONS 15302 system.

1.1 Critical Safety Warnings

Warning Do not perform cabling on an electrically-live system. Ensure that all power is removed from the shelf before continuing with this procedure. Actual wire gauge should be determined based on local engineering standards and practices.

Warning Before connecting 48 V power to the ONS 15302, remove the fuses from both the A and B sides of the power distribution panel (PDP). Failure to do so can cause serious injury or death. Actual wire gauge should be determined based on local engineering standards and practices.

Warning Before connecting 230 V power to the ONS 15302, remove the fuse from the 230 V power supply. Failure to do so can cause serious injury or death. Actual wire gauge should be determined based on local engineering standards and practices.

Warning Before installing the ONS 15302, remove the fuses from both the A and B sides of the PDP. Failure to do so can cause serious injury or death.

Warning Touching electrical connectors or other exposed electrical circuitry inside the ONS 15302, when they are energized can cause serious injury or death.

1.2 General Safety Precautions

General safety precautions are not related to any specific procedures and do not appear elsewhere in this publication. Personnel must understand and apply the following precautions during installation and testing of the ONS 15302 system.

•Know standard electrical safety and electrical wiring and connection practices.

•Be familiar with cardio-pulmonary resuscitation (CPR). Obtain this information through the appropriate national authority (such as the Red Cross or the local equivalent). This knowledge is imperative for personnel working with or near voltages with levels capable of causing injury or death.

1.3 Recommended Safety Precautions

The following precautions are recommended when working on the ONS 15302 system:

•Keep your work area tidy and free of obstructing objects at all times.

•Do not wear loose clothing, jewelry, or other items that could be caught in the components during installation or use.

•Use the equipment only in accordance with the electrical power rating.

•Do not work alone if hazardous conditions may exist in your workplace.

•Install the ONS 15302 components in compliance with the following local and national electrical codes:

–In the United States: National Fire Protection Association (NFPA) 70; US National Electrical Code

–In Canada: Canadian Electrical Code, part I, CSA C22.1

–Elsewhere: International Electrotechnical Commission (IEC) 364, part 1-7

•Properly ground the equipment.

•Connect only a DC power source that complies with the safety extra-low voltage (SELV) requirements in UL1950, CSA 950, EN 60950, and IEC950 to an ONS 15302 DC power supply input.

•Install DC power supplies used in restricted access areas in accordance with Articles 110-16, 110-17, and 110-18 of the National Electric Code, ANSI/NFPA 70.

•Terminate all laser outputs properly before connecting laser inputs.

•Disconnect the input end of an optical fiber jumper cable before disconnecting the output end.

•Handle glass fiber with care. Glass fiber can be broken if mishandled. Using broken fiber can result in permanent equipment damage.

•Protect skin from exposed glass fiber. It can penetrate the skin.

•Limit the number of personnel that have access to lightwave transmission systems. Personnel should be authorized and properly trained if access to laser emissions is required.

•Limit the use of laser test equipment to authorized, trained personnel during installation and service. This precaution includes using optical loss test (OLT) set, optical spectrum analyzer, and optical time domain reflectometer (OTDR) equipment.

•Exclude any unauthorized personnel from the immediate laser radiation area during service and installation when there is a possibility that the system may become energized. Consider the immediate service area to be a temporary laser-controlled area.

•The ONS 15302 system functions in the 1270 - 1335 nm window, which is considered invisible radiation. You cannot see the laser light being emitted by a fiber, a pigtail, or a bulkhead connector. Use appropriate eye protection during fiber-optic system installation or maintenance whenever there is potential for laser radiation exposure, as recommended by the company's health and safety procedures. Observe this precaution whether warning labels have been posted.

1.4 Safety Symbols and Labels

The ONS 15302 equipment is clearly printed with warning about the equipment radiation level. Read and understand all warning notes before working with the equipment.

The ONS 15302 has a warning note located left from the optical connector. The warning note consists of warning text CLASS 1 LASER PRODUCT.

1.5 Electrostatic Discharge Cautions

Some ONS 15302 components are classified as Class 0 ESD-sensitive devices. Adhere to the following rules:

•Observe standard precautions for handling ESD-sensitive devices.

•Assume that all solid-state electronic devices are ESD-sensitive.

•Ensure that you are grounded with a grounded wriststrap or equivalent while working with ESD-sensitive devices.

•Transport, store, and handle ESD-sensitive devices in static-safe environments.

1.6.4 Unterminated Fiber Warning


Warning	Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not view directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard.
Waarschuwing	Er kunnen onzichtbare laserstralen worden uitgezonden vanuit het uiteinde van de onafgebroken vezelkabel of connector. Niet in de straal kijken of deze rechtstreeks bekijken met optische instrumenten.

Avvertenza	L'estremit� del connettore o del cavo ottico senza terminazione pu� emettere radiazioni laser invisibili. Non fissare il raggio od osservarlo in modo diretto con strumenti ottici. L'osservazione del fascio laser con determinati strumenti ottici (come lupette, lenti di ingrandimento o microscopi) entro una distanza di 100 mm pu� provocare danni agli occhi.
Advarsel	Usynlig laserstr�ling kan emittere fra enden av den ikke-terminerte fiberkabelen eller koblingen. Ikke se inn i str�len og se heller ikke direkte p� str�len med optiske instrumenter. Observering av laserutgang med visse optiske instrumenter (for eksempel �yelupe, forst�rrelsesglass eller mikroskoper) innenfor en avstand p� 100 mm kan v�re farlig for �ynene.
Aviso	Radia��o laser invis�vel pode ser emitida pela ponta de um conector ou cabo de fibra n�o terminado. N�o olhe fixa ou diretamente para o feixe ou com instrumentos �pticos. Visualizar a emiss�o do laser com certos instrumentos �pticos (por exemplo, lupas, lentes de aumento ou microsc�pios) a uma dist�ncia de 100 mm pode causar riscos � vis�o.
�Advertencia!	El extremo de un cable o conector de fibra sin terminaci�n puede emitir radiaci�n l�ser invisible. No se acerque al radio de acci�n ni lo mire directamente con instrumentos �pticos. La exposici�n del ojo a una salida de l�ser con determinados instrumentos �pticos (por ejemplo, lupas y microscopios) a una distancia de 100 mm puede comportar lesiones oculares.
Varning!	Osynlig laserstr�lning kan komma fr�n �nden p� en oavslutad fiberkabel eller -anslutning. Titta inte rakt in i str�len eller direkt p� den med optiska instrument. Att titta p� laserstr�len med vissa optiska instrument (t.ex. lupper, f�rstoringsglas och mikroskop) fr�n ett avst�nd p� 100 mm kan skada �gonen.
