xvi About this document

Introduction to a high level procedure This document contains procedures that provide information necessary for an experienced user to perform a particular task. Requirements, main procedure tasks and expected results are consolidated into a single procedure. The step numbers in parenthesis provide links to specific steps in the complete procedure. Warnings, caution or danger messages are embedded in the procedure along with the precautionary message icons.

Example of a high level procedure Before you start • Obtain a user account and password that allows you to access the OME6130 network element with privileges for creating and modifying user accounts. • Be familiar with the OME6130 network element user interface as illustrated in the Local Craft Access User Guide, 323-1855-195.

Procedure tasks • Log into the OME6130 network element with appropriate access privileges (step 1). • Create a new user account (step 2). • Assign a password to the new user account (step 4).

Expected results • A success message is displayed. • If the expected results do not occur, contact your next level of support.

Observing product and personnel safety guidelines

1-

This chapter contains safety guidelines that you must follow for personal safety and to operate the equipment correctly. Nortel Networks documentation contains precautionary messages and safety procedures that refer to specific tasks or conditions. You must read and follow all precautionary messages before you start to work on the equipment.

Audience Personnel working directly on equipment must be • trained, authorized, and qualified to carry out the tasks required • able to follow safety guidelines specific to the product and all local customer-specific safety procedures

Precautionary messages To prevent personal injury, equipment damage, and service interruptions, you must follow all precautionary messages in Nortel’s documentation and all local safety standards required by your company. The following precautionary messages appear in Nortel’s documentation: DANGER Risk of personal injury

A precautionary message with this symbol indicates a risk of personal injury. DANGER Risk of electrical shock

A precautionary message with this symbol indicates a risk of personal injury caused by an electrical hazard.

Trouble Clearing and Module Replacement Procedures 323-1855-543 Standard Rel 2.0 Iss 1 Jun 2007

1-2 Observing product and personnel safety guidelines

DANGER Risk of laser radiation exposure

A precautionary message with this symbol indicates a risk of personal injury caused by exposure to a laser beam.

WARNING Risk of burn

A precautionary message with this symbol indicates a risk of personal injury caused by a hot surface. CAUTION Risk of interruption to service

A precautionary message with this symbol indicates a risk of service interruption or equipment damage. CAUTION Risk of damage to circuit packs

A precautionary message with this symbol indicates a risk of static damage to circuit packs. Use antistatic protection.

Safety standards Nortel’s network elements conform to all relevant safety standards. The OME6130 complies with the following safety standards: • IEC/EN 60950-1:2001—Information technology equipment - Safety, Part 1: General requirements • IEC 60825-1:2001 and IEC 60825-2:2004 Safety of Laser Products • FDA 21 CFR 1040—Performance Standards for Light-Emitting Products, 1997

Laser radiation—optical transmission systems Nortel’s optical products use laser or light-emitting diode (LED) sources that emit light energy into optical fibers. This energy is within the red (visible) and infrared (not visible) areas of the electromagnetic spectrum.

International standards The IEC 60825 series of international standards cover the safety of laser and LED products. The following list provides examples from the International Electrotechnical Commission (IEC), Code of Federal Register (CFR), and European Norm (EN) series of standards: • IEC 60825-1, Safety of Laser Products—Part 1: Equipment Classification, Requirements and User’s Guide Edition 1.1; Edition 1: 1993, Consolidated with Amendment 1: 1997; Issue 1, 1998 (123 pgs) (Part 1 of a series of publications under the general title of: Safety of Laser Products) and Amendment 2: 2001. This standard provides information about equipment classification and on limit values for the safety of laser products. Note: In Europe, the EN 60825 series of standards for CE marking purposes evaluate the safety of laser and LED products. The EN 60825 series is technically equivalent to IEC 60825. •

IEC 60825-2:2004-06, Safety of laser products Part 2: Safety of Optical Fiber Communication Systems, Third Edition, June 2004, 56 pgs. This standard provides information about the safety of optical fiber communication systems. Regional standards such as the EN 60825 series: for example, British Standard BS EN 60825-1:1994, Safety of Laser Products, Equipment Classification, Requirements and User’s Guide, 15 Dec 1994, 123 pgs. These standards are based on the IEC 60825 series. Note: In Europe, the EN 60825 series of standards for CE marking purposes evaluate the safety of laser and LED products. The EN 60825 series is technically equivalent to IEC 60825. In the United States, the Food and Drug Administration (FDA), publishes regulations 21 CFR 1010, Performance Standards for Electronics Products: General, April 1996, and 21 CFR 1040 in the Code of Federal Register (CFR). Regulations 21 CFR 1010 and 21 CFR 1040 contain laser safety requirements equivalent to the European standards. Note: FDA Laser Notice 50, issued by the US Department of Health and Human Services (FDS) on July 26, 2001, now states that there is no objection to the FDA conforming with IEC labels as specified in IEC 60825-1. This is in an effort on the part of the FDA to align its standards for laser products with international standard IEC 60825-1.

Nortel Networks ensures that all its products are compliant with either or both FDA and IEC requirements, as required.

Laser radiation hazards The maximum radiation hazard encountered when disconnecting an optical fiber or during a fiber break does not exceed the accessible emission limit (AEL) for Class 1 (IEC) or Class I (FDA). The worst case hazard level as defined by IEC 60825-2 is Hazard Level 1, and defined by ANSI Z136.2 as a Service Group 1. Because the system is intended to be installed in a restricted access location, no additional engineering design features are required to prevent exposure to the laser radiation. Labeling The OME6130 system and circuit packs have been labeled in accordance with IEC 60825-1, IEC 60825-2 and FDA Laser Notice 50 (Dated July 2001). Circuit pack labels The optical interface has a laser aperture warning label located on the right bottom of the OME6130 chassis. The element of a typical circuit pack explanatory label is a laser warning symbol and a laser hazard level statement in accordance with IEC 60825-2:2000. OME6130 chassis do not use lasers that exceed the AEL for Class 1, and therefore, do not require wavelength and optical power information at the aperture. The information is provided in this chapter for every optical circuit pack • wavelength, shown as a nominal value or dense wavelength division multiplexing (DWDM) range of values, such as in the following examples: — 1310 nm nominal indicates a single wavelength in the range of 1270 nm to 1360 nm — 1550 nm nominal indicates a single wavelength in the range 1525 nm to 1625 nm • •
