22 iPasolink250 Installation and Commissioning Guide Document ID: 141-DOC000008-E Specification Standard Compliance Safety Certified for CB – Scheme IEC 60950 / EN 60950 UL 60950 CAN/CSA-C22.2 No. 60950 Laser Safety IEC 60825-1 / EN 60825-1 IEC 60825-2 / EN 60825-2 21 Code of Federal Regulations (CFR)1040 Safety Recommendations This section lists the safety recommendations that need to be followed for safe operation of the network element. General Safety Guidelines  Keep the chassis clean and dust-free before, during and after the installation.  Keep tools away from the area where you and others could fall over them.  Avoid wearing loose cloths that could get caught in the chassis. Fasten your tie or scarf and roll up your sleeves before handling the equipment.  Wear safety glasses if you are working under any conditions that might hazardous to your eyes.  Do not perform any action that creates a potential hazard to people or make the equipment unsafe. Maintaining Safety with Electricity Follow the listed guidelines while working on equipment powered by electricity: 1. Locate the emergency power-off switch for the room in which you are working. Then, if an electrical accident occurs, you can act quickly to turn off the power. 2. Disconnect all power by turning off the power and unplugging the power cord before: Installing or removing a chassis Working near power supplies 3. Do not work alone if potentially hazardous conditions exist. 4. Never assume that power is disconnected from a circuit. Always check the circuit to confirm. 5. Look carefully for possible hazards in your work area, such as cords, and missing safety grounds. If an electrical accident occurs, proceed as follows: Turn off the system. Determine if the person needs rescue breathing or external cardiac compressions, and then take appropriate action.
23 Chapter 3 Observing Safety Guidelines Preventing Electrostatic Discharge Damage Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage occurs when electronic components are improperly handled and can result in complete or intermittent failures. To ensure optimal electrostatic discharge protection:  Always follow ESD-prevention when removing and replacing components.  Ensure that the chassis is electrically connected to earth ground.  Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact.  Connect the grounding clip to an unpainted surface of the chassis frame to safely ground ESD voltages.  The wrist strap and cord must operate effectively to properly guard against ESD damage and shocks. If no wrist strap is available, ground yourself by touching the metal part of the chassis.  For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 Mega Ohms (MOhm). Site Environment Network element can be mounted in a rack. The location of the network element, the layout of your network element rack including wiring room is extremely important for proper system operation. Network element placed closer to each other, inadequate ventilation, and inaccessible panels can cause system malfunctions and shutdowns, which calls for unscheduled system maintenance. While planning your site layout and network element locations, consider the precautions described in the section "Preventive Site Configuration on page 24" to understand how to avoid network element failures and reduce the possibility of environmentally caused shutdowns. If you are currently experiencing shutdowns or unusually high errors with your existing network element, these precautions may help you isolate the cause of failures and prevent potential problems. General Site Requirements This section describes the requirements your site must meet for safe installation and operation of the system. Before installation, verify the site for readiness as per the site verification checklist given in "Site Verification Checklist".
24 iPasolink250 Installation and Commissioning Guide Document ID: 141-DOC000008-E Preventive Site Configuration Take following precautions to plan an acceptable operating environment for your network element and to avoid environmental equipment failures:  Electrical equipment generates heat. Without adequate air circulation, the ambient air temperature might not be adequate to cool equipment to acceptable operating temperatures. Ensure that the room in which you operate your system has proper ventilation.  Damage from static discharge can cause immediate or intermittent equipment failure. Always follow the ESD prevention procedures to avoid damage to equipment.  An open chassis allows air leaks, which may interrupt and redirect the flow of cooling air from internal components. Ensure that the chassis cover is secure to allow cooling air to flow effectively from right to left within it. CAUTION: Proper hydraulic/pneumatic material handling equipment must be used for mounting the equipment. If the network element is heavy and the hydraulic equipment is not available then ensure that at least two installers are at the installation site. Configuring Equipment Racks While planning an acceptable equipment rack configuration, ensure that:  The enclosed racks have adequate ventilation and are not overly congested.  The enclosed rack should have lowered sides and a fan to provide cooling air, since each unit generates heat.  The rack frame does not block the intake or exhaust ports while chassis is mounted in an open rack.  Chassis is placed at the right position into the rack, if the chassis is installed on slides.  Adequate ventilation is available for equipment at the bottom of the rack. In an enclosed rack with a ventilation fan in the top, excessive heat generated by equipment near the bottom of the rack can be drawn upward and intake ports of the equipment.  Baffles helps isolating exhaust air from intake air, which also helps to draw cooling air through the chassis. The best placement of the baffles depends on the airflow patterns in the rack. Experiment with different arrangements to position the baffles effectively. Working with Power Supply Unit When you install power feeds to the product input terminals or if you perform routine power maintenance, make sure that you do the following:  Read the power procedures before you perform any function.  Use appropriate insulated tools to perform any tasks.
25 Chapter 3 Observing Safety Guidelines The green LED continuously lit at the faceplate on the base card indicating that the card is powered up and is functioning correctly. If the green LED on the PSU is ON, the power at the associated feeder is present and the conditions can be assumed to be normal. Some of the possible cases when the green LED on the base card is not ON are:  Power supply unit is damaged or non-functional.  Base card is damaged or non-functional.  Feeder low voltage or power failure  Over-current failure  Blown fuse in the power supply unit due to the reverse polarity condition at the input terminals. The circuit breaker on the power supply unit is an electronic circuit breaker that cuts off the power to the card on over-current condition. RISK OF ELECTRICAL SHOCK: The battery feeds can be at a high enough potential to constitute a shock hazard. Use the appropriate insulated tools when working with power unit. RISK OF PERSONAL INJURY, ENERGY HAZARD: The battery feeds are capable of supplying very high current which, during an unintentional short, can cause burns. Use the appropriate insulated tools when working with power unit. Preventing Damage to Card and Pluggable Module In this section, the generic term 'card' is used to refer to cards or pluggable modules as applicable. These cards are shipped to the customer premises in shielded containers. All cards are subject to damage by rough handling or by electrostatic discharges. NOTE: Follow precautions for handling electrostatic sensitive devices. While handling, installing, storing or replacing cards, take the following necessary precautions:  Wear an antistatic wrist-strap, a heel grounder, or another personal grounding device before you remove a module from its package or from the shelf.  Follow installation and removal procedures for each module. Make sure to understand and perform each precautionary message in these procedures (for example, opening or closing the latches of the card simultaneously).  Do not touch the solder side of the module, the pin connector, or the components.
26 iPasolink250 Installation and Commissioning Guide Document ID: 141-DOC000008-E  Inspect all pin connectors for damage before using them on each module.  Inspect each module for damage before inserting the component into the shelf.  Store uninstalled cards separately in a shielded box.  Do not stack cards on or against each other.  Do not force cards into their packaging material.  Do not store several cards in the same container.  Allow each module to reach room temperature before you insert the module into the shelf.  When not in use store pluggable modules in their protective static-dissipative containers to prevent damage to the exposed connector terminals.  Leave spare cards in the original shielded containers until you need the cards.  To prevent damage to cards in storage, follow procedures that prevent accumulation of dirt or dust on the pin connectors and damage to the printed-circuit board or its components wrapage. This situation is typical for printed-circuit boards stored in areas where the humidity can exceed 95% and the temperature can exceed 70 °C.  While transporting cards, pack each module in its original shielded container and padding, or in an electrostatically shielded bag. In case the original packing material is lost, place the module in a shielded bag and use another container with sufficient padding.  Air filters have to be replaced once in 6 months. Dissipating Static Electricity The static electricity level in your body increases when you move around or come into contact with other charged surfaces. Excessive levels of static electricity can damage the equipment. You must either wear a properly functioning heel grounder (that attaches to your leg and foot) and/or an antistatic wrist-strap, or another grounding device when you work on any of the following:  Network element chassis (including the metal frame and cover)  Cables connected to cards  Cards Any one of the previously mentioned grounding devices dissipates electrostatic charges to the ground quickly and safely. Use grounding devices correctly to eliminate the ESD threat you pose to the equipment. When you wear an antistatic wrist-strap or a heel grounder, you must make sure the grounding straps are in contact with a moist part of your skin. Connect the grounding cord to the grounding plug on a grounded fixture of the product you are working on, such as the shelf ESD jack, grounded fixtures are accessible on most of the products.
27 Chapter 3 Observing Safety Guidelines CAUTION: Heel grounders or similar worn footwear attachments work when the floor is designed to dissipate static electricity. Also check for the ESD foot wear attachment connectivity to ground using suitable ESD tester. If the properties of the floor are unknown or in doubt, use a wrist-strap and make sure it is connected to a piece of electrostatic discharge (ESD) grounding equipment before proceeding with any maintenance or installation activity. The following guidelines provide an optimal electrostatic discharge protection:  Install bays on conductive floor coverings.  Provide conductive shoes, antistatic wrist-straps and heel grounders to all personnel working on the equipment.  Maintain local environmental conditions so that relative humidity around equipment to be serviced is in excess of 20% (preferably higher than 40%). This lowers the threat of developing damaging electrostatic levels.  Implement an ESD training and control program that educates personnel on the hazards of ESD and simple mitigation procedures that can easily be applied. Controlling Equipment Environment The maximum operational long-term ambient temperature of the system location is 40 °C. A temperature above 40 °C is permissible (according to ETSI EN 300 019-1-3 V2.1.2 Edition 2003-04 for Environmental Class 3.1: Temperature controlled locations and ETSI EN 300 019-2-3 V2.1.2 for Environmental Class T3.1 and T3.1E: Temperature controlled locations) provided the probability of occurrence is less than 1%. A temperature of 50 °C is permissible but the duration should not exceed 72 continuous hours. Using Optical Fibers Optical fibers are either single mode or multiple modes. The information in the following sections applies to all optical fibers. Handling Optical Fibers When handling optical fibers:  Wear safety glasses when you install optical fibers.  Do not look into the opening of an optical fiber, or the opening of an optical fiber connector, if the optical fiber is active or the unit has the power turned on.  Avoid direct exposure to optical fiber ends or optical connector ends where you can access the laser signal directly.
28 iPasolink250 Installation and Commissioning Guide Document ID: 141-DOC000008-E LASER RADIATION EXPOSURE RISK: Do not look directly into the optical beam. Invisible light can severely damage your eyes. Keep all optical connectors capped. Splicing Optical Fibers Before looking at a spliced optical fiber with a magnifier:  Power off all laser sources to the optical fiber or disconnect the remote optical fiber end from the laser sources before you start splicing. The laser sources can be in a central office, on subscriber premises, or in a remote location.  Disconnect all optical test sets from the optical fiber before you start splicing. The connections can be local or remote.  Use only the optical instruments approved by your company. When splicing optical fibers:  Clean your hands after you handle optical fibers. Small pieces of glass are not always visible and can damage your eyes.  Do not handle pieces of optical fiber with your fingers. Use tweezers (preferably non metallic) or adhesive tape to lift and discard any loose optical fiber ends.  Wear rubber gloves when you clean optical connectors. The gloves prevent direct contact with the isopropyl alcohol and prevent contamination of the ferrules with skin oils.  Place all optical fiber clippings in a plastic container provided for that purpose.  Handle optical fibers with caution. Place the optical fibers in a safe location during installation.  Protect all optical fiber connectors with clean dust caps at all times.  Follow the manufacturer instructions when you use an optical test set. Incorrect calibration or control settings can create hazardous levels of radiation. EYE INJURY RISK: If you have a piece of a glass in your eye, get medical assistance immediately. Repairing Optical Fibers When an accidental break occurs in the optical fiber:  Report the location of the damaged optical fiber to both the central office and the field repair personnel.  Power-off all laser sources to the optical fiber or disconnect the remote optical fiber end from the laser sources. The laser sources can be in a central office, on subscriber premises, or in a remote location.

75 This chapter describes the procedures to be followed when cleaning and inspecting optical and fiber connectors. It also describes the procedure to be followed during inserting and ejecting of cards and fan trays. NEC recommends that you always clean fiber-optic connectors before connecting to transmission equipment, test equipment, patch panels, or other connectors. Cleaning Fiber Connectors 1. Clean the fiber end with a new lint-free cleaning pad, lens tissue, or swab. Move the cleaning pad back and forth across the fiber end several times. If you are using a swab, gently rotate the swab as you wipe across the end face. 2. Clean the ferrules and other parts of the connector with a lint-free, non abrasive cleaning pad or lens tissue. After you finish, discard the used pad or tissue. 3. Aim a filtered, dry compressed-air dust remover at a shallow angle to the fiber end face and blow across the end face from a distance of 6–8 inches. 4. Verify whether the other end of the fiber is disconnected from its laser source. Inspect the fiber-optic connector with an optical fiber scope to verify that it is free of dirt and dust. Then do either of the following: If the connector is clean, cover the connector with a protective dust cover until ready to use it. If the connector is not completely clean, continue with steps 5 to 13 to clean it with alcohol. 5. Apply 99% isopropyl or ethyl alcohol to a lint-free, non-abrasive cleaning pad or lens tissue. 6. Clean the ferrules and other parts of the connector with a lint-free, non abrasive cleaning pad or lens tissue. After you finish, discard the used pad or tissue. 7. Apply alcohol to a new, lint-free cleaning pad, lens tissue, or swab. 8. Clean the fiber end with a new lint-free cleaning pad, lens tissue, or swab. Move the cleaning pad back and forth across the fiber end several times. If you are using a swab, gently rotate the swab as you wipe across the end face. 9. Immediately dry the fiber ends with a clean, dry, lint-free cleaning pad or lens tissue. 10. Discard the used cleaning materials. 11. Aim a filtered, dry compressed-air dust remover at a shallow angle to the fiber end face and blow across the end face from a distance of 150-200 mm. Appendix III General Procedures
76 iPasolink250 Installation and Commissioning Guide Document ID: 141-DOC000008-E 12. Inspect the fiber-optic connector with an optical fiber scope to verify whether it is free of dirt and dust. 13. Cover the connector with a protective dust cover until it is ready to be used. Cleaning Optical Connectors It is important to keep all interconnects as clean as possible. Since the single-mode fiber has a light-carrying core with diameter less than 10 micro meters, even a single microscopic speck of dust on the connector end can significantly attenuate the light traveling through the fiber. Clean connections are required for accurate and repeatable measurements. Leave the protective dust covers on the connectors when they are not in use. Observe the following guidelines to achieve the best performance:  Visually inspect fiber ends to locate any signs of damage.  Use dry connections whenever possible.  Keep connectors covered when not in use. For more information on cleaning procedure, refer to "Cleaning Fiber Connectors on page 75". CAUTION: Improper cleaning may result in high attenuation due to dirt or dust or may cause mechanical damage to the fiber end, resulting in performance degradation. While handling an optical fiber, do not exceed the minimum bed radius (35 mm). Do not over tighten the cable tie wraps while dressing the cable. DANGER: Do not look into the end of fiber-optic connectors or into faceplate connectors of installed circuit packs. The light source used in fiber-optic devices can damage your eyes. The following items are recommended for cleaning the optical connectors:  99% isopropyl or ethyl alcohol  Lint-free, non abrasive optical-quality cleaning pads or lens tissue, or cotton or urethane-foam swabs.  Pressurized dry-air duster.  Optical fiber scope.
