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".
23
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.
24
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.

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.
26
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 300 019-23 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.
27
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.

Setting Ethernet IP, Subnet Mask, Router ID, and Port
Rate on the Network Element
Ethernet IP
Each network element has a network management system (NMS) interface which is a 10/100
Mbps network interface controller (NIC) port. Ethernet IP is the IP address with which the
network element communicates with the external world.
Subnet mask length
The subnet mask length is an optional parameter that corresponds to the Ethernet IP address.
Subnetting is used to set the subnet mask parameters.
NOTE: The subnet mask for a point-to-point connection (that is, a direct Ethernet
connection between the WUI host and the network element) should be set to 32.
Router ID
Network element communicate in the network over the embedded communication channel
(ECC), using the router ID. A network element can be configured either as a gateway element
(interconnecting two networks) or just a pass-through network element.
Before setting the Ethernet IP, Subnet Mask, Router ID, and Port Rate on the Network Element:
 Log into network element WUI using the NMS port.
 Ensure your PC is correctly connected to the network element through the NMS interface.
 Ensure that you have the Ethernet IP address, router ID, sub net mask and static route IP of
the network element to be configured.
 Ensure the PC is configured in the same NMS as the network element.
To set the Ethernet IP, Subnet Mask, Router ID, and Port Rate on the Network Element,
1. Connect the laptop with static IP 192.168.1.x to the node so that, it can be accessed.
2. Launch the Internet Explorer 8.0/ Firefox 3.6 browser and enter the URL

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.

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 urethanefoam swabs.
 Pressurized dry-air duster.
 Optical fiber scope.

Appendix III General Procedures
Ejecting Cross-Connect Cards
To eject the cross-connect card:
1. Press the RST (Reset) switch till LED status displays 'RED' color and release the switch
immediately. Sts (Status) LED displays 'RED' color. During this card goes for booting
process.
2. Once the process is complete, Sts (Status) LED displays 'RED BLINKING' color. This
indicates that card is ready for Jack-Out. Now slave cross-connect card will become Master
cross-connect card.
3. Remove the screws located at either end of the face plate using Philips (PH1) screwdriver.
4. Operate the two ejector levers (outwards) to disengage the card from the backplane.
5. Slide out the card with the ejector levers in horizontal position along the guide ways.
Inserting and Ejecting Cards
This section details the insertion and ejection of the cards in a network element. The cards are
provided with ejectors that aid in their insertion and ejection from the chassis.
STATIC ELECTRICITY: Static electricity can damage the equipment. While
unpacking and handling cards, or making network element interconnections, wear a grounding
wrist strap to discharge the static buildup.
CAUTION: If any of the plug-in units or interface modules need to be inserted or
ejected, it is imperative that the following procedures are adopted to avoid possible damages
to the connectors or spring fingers.
To insert a card in a network element:
1. Identify the appropriate slot into which the card is to be inserted.

LC CONNECTOR
Data Communication Network is SDH network
that enables OAM communication between
individual network elements as well as inter
network element communication.
Lucent Connector. An optical fiber connector
terminates the end of an optical fiber, and
enables quicker connection and
disconnection than splicing. The connectors
mechanically couple and align the cores of
fibers so that light can pass. LC connectors
are replacing SC connectors in corporate
networking environment due to its smaller
size.
DHCP
Dynamic Host Configuration Protocol. A
protocol used by networked devices (clients)
to obtain various parameters necessary for
the clients to operate in an Internet Protocol
(IP) network. By using this protocol, system
administration workload greatly decreases,
and devices can be added to the network
with minimal or no manual configurations.
MAC ADDRESS
Media Access Control address. An address—
typically made up of numbers and letters—
assigned to your hardware that uniquely
identifies its place on the network.
ELAN
Emulated Local Area Network. An emulated
LAN is a set of clients and servers
connected by virtual circuits over a network.
OSPF
Open Shortest Path First. A dynamic routing
protocol for use in Internet Protocol (IP)
networks.
EOW
Engineering Order Wire. An operator's
communication channel that supports a 2wire analog telephone.
PDH
Plesiochronous Digital Hierarchy (PDH). A
technology used in telecommunications
networks to transport large quantities of
data over digital transport equipment such as
fibre optic and microwave radio systems.
