Operation Safety Rules

High optical power can cause bodily harm, especially to eyes. Never look directly into the end of the optical transmitter fiber jumper or the end of its active connector.

Do not touch any component or wires on cards, or metal conductors in sockets. ESD protection measures should be taken if it is necessary to touch the card during maintenance. Carpets or other materials that easily generate static electricity should not be used on the floor of equipment room.

Optical communication equipment must be protected from electrical surges, thunder and lightning.

Exercise care if you must bend fibers. If bends are necessary, the fiber bending radius should never be less than 38 mm.

Do not open the active fiber connector unnecessarily. If it is necessary to open it for equipment maintenance, protection measures should be taken to avoid contaminating the end face of connector.

The network management system requires a dedicated computer. Use of unidentified memory devices should be prohibited so as to avoid computer viruses.

When maintaining or testing the equipment, connect the instrument earth ground cable with the equipment (or the cabinet where the equipment is installed) earth ground cable properly.

Damaging the grounding may inhibit proper operation of the equipment and should be avoided.

A good protection earth ground should be provided before the equipment installation.

Before the equipment is powered on, the protection earth ground cable of its chassis should be well grounded. Check that the insulation resistance and ground resistance meet the specification; and that the power ground is making a good connection.

Human safety

Do not install / operate the equipment or lay cables during a lightning storm.

1 Operation Safety

Version: A 1-3

Direct or indirect contact (through damp objects) with high voltage power supply can cause bodily harm and should be avoided.

Do not connect or remove the power cable while it is powered. Do not insert the power cable without a plug directly into the socket.

To prevent laser radiation from injuring eyes, do not look into the end face of the fiber or fiber connector directly with naked eyes.

Before installing the equipment, users should wear ESD protection clothing and a wrist strap. Do not wear conductive articles such as jewelry and watches to prevent electric shock and burn.

During the installation, the tools used (such as a soldering iron) should be electrically insulated and must be used and placed properly; otherwise they may do harm to human body and cause damage on the equipment or circuit board.

In case of fire, users should evacuate the building or equipment area, and activate any alarm system or make a fire alarm call.

Equipment safety

Do not install the equipment before construction of the equipment room is completed.

When moving or lifting the equipment, avoid collisions with other hard objects.

Never stack two or more pieces of equipment to move together, so as to avoid collapse and wear.

The equipment should be installed in a place that is away from direct sunlight but has good ventilation.

Do not place the equipment near flammable, explosive, corrosive materials or in an atmosphere with solvent gases or smoke.


1-4 Version: A

1.2 Mechanical Safety

During the operations for the equipment, we always need to use various tools; and the proper operation with tools may avoid accidental bodily injury and equipment damage. This section introduces safety precautions for drilling holes, handling sharp objects and working at heights.

Drilling

Drilling on the cabinet without prior authorization is strictly prohibited. Drilling may damage the electromagnetic shield (EMS) performance and the wires and cables inside the equipment. If the metal filings from the drilling fall into the cabinet, it may result in an electrical short circuit on one or more circuit boards.

During the drilling, users should fully comply with the prescribed safety measures, and should confirm the position, dimension and depth first.

Before drilling, wear close fitting sleeves or bind up the cuffs.

Clean the metal shavings with a vacuum immediately after completing the drilling operation. Do not blow metal shavings away using compressed air, by mouth or other means. Do not pick metal shavings up by hand.

Sharp objects

When carrying the equipment by hand, wear the protective gloves to avoid injury by sharp objects.

Generally, two persons are needed for lifting or moving the cabinet. Lift the cabinet by grasping its lower edges from both ends, and place it on the ESD protection cushion with good grounding. When moving the cabinet, use care not to collide with other objects.

Using a ladder

Before using a ladder, first check whether the ladder is solid enough to stand on. The ladder shall be put into use only after it is checked and found to be qualified.

The suitable slant angle of the ladder ranges from 60 to 70 as shown in Figure 1-1. The ladder should be placed on stable ground.

1 Operation Safety

Version: A 1-5

Figure 1-1 Slant angle of ladder

The width of ladder should be no less than 50 cm; and the ladder should be equipped with anti-skid feet to prevent slipping.

Ensure that your center of gravity does not deviate from the ladder edge. To reduce the danger and ensure safety, maintain your balance on the ladder before and during any operation.

Installation personnel should wear anti-skid shoes. Avoid stepping on any cable, the cabinet or other equipment. Keep all objects secured, preventing them from falling on top of or hitting the equipment. Protect the cabinet top from the construction wastes such as metal filings.


1-6 Version: A

1.3 Electrical and Electronic Safety

This section describes safety precautions for electricity and ESD.

1.3.1 Electrical Safety

Related knowledge

Do not connect or remove the power cable while it is powered, because the transient contact between the core of the power cable and the conductor may generate electric arc or spark, which may cause fire or bodily injury.

Safety measures

Operators must follow the rules below, to ensure electricity security.

Avoid connecting or removing the power cable without disconnecting power supply.

Before connecting the power cable, confirm that its label meets the requirement.

1.3.2 Electrostatic Discharge

Related knowledge

The static electricity generated by the human body may damage the electrostatic sensitive components on the circuit board, such as the large-scale integrated circuit (LSI).

The human body can generate static electromagnetic fields from the friction between the skin and the clothing, clothing friction, and the friction between shoes and the floor during the physical movement. And such static electromagnetic effects can remain for an appreciable time on the body.

1 Operation Safety

Version: A 1-7

Safety measures

Before operating the equipment or holding a card, wear an ESD protection wrist strap that is properly grounded, so as to prevent the electrostatic sensitive components from being damaged by the static electricity in the human body.

Figure 1-2 shows the method of wearing an ESD protection wrist strap.

Figure 1-2 Wearing an ESD protection wrist strap


1-8 Version: A

1.4 Laser Safety

Related knowledge

Laser transceivers / transmitters are used in the optical transmission system and associated test tools. Because the laser being transmitted through the optical fiber produces a small beam of light, it has the very high power density and is invisible to human eyes.

When a beam of light enters the eye, retina may be hurt. Viewing an un-terminated fiber or damaged fiber with the unaided eye at distances greater than 150 mm will normally not cause eye injury. However, damage may occur if an optical tool such as a microscope, magnifying glass or eye loupe is used to view the energized fiber end.

Safety measures

To avoid laser damage, obey the following instructions:

All operations should be performed by authorized personnel who have relevant qualifications.

Wear a pair of protection eye glasses when you are handling or near a strong laser.

Never look directly into the end face of the optical fiber or connector.

Use an optical power meter to check and ensure that the optical source is switched off by measuring the optical power.

When handling or near a laser, do not wear reflective objects as jewelry and watches to prevent accidental eye injury.

Before cutting or splicing optical fibers, ensure the fibers is disconnected from the optical source.

1 Operation Safety

Version: A 1-9

1.5 Other Safety Precautions

This section introduces safety precautions for plugging / unplugging cards, binding cables and laying cables.

Installing / uninstalling a card

When plugging / unplugging a card, wear an ESD protection wrist strap and slide the card gently along the slide rails to avoid distorting pins on the backplane.

Prevent the circuit surfaces of cards from contacting each other, to avoid shorting or scratching.

Always wear an ESD protection wrist strap when touching a card's circuitry, components, connectors, or wiring trough, so as to prevent damage to sensitive devices caused by electrostatic discharge.

Binding cables

Installers should bind all wires and cables used in onsite installation. Each cable type should be bound separately. For example, power cables, alarm cables and optical fibers should be laid out independently and bound separately. Note that optical fibers cannot be bound with typical wire binder.

After completing the equipment installation, do not adjust the position of the equipment or cables.

Laying cables

If the temperature is too low to allow proper cable handling measures should be taken to warm cables before handling.

When carrying cables, especially in low temperature, users should treat them with great care. When transporting cable for short distances it is common practice to roll the cable spool. When rolling cable spool always follow the direction indicated by the arrow on the spool. If there is no arrow indication on the spool, follow the direction that the cable is wound on the spool. Never roll the spool in the opposite direction as the cable ring may become loose.

The cable staging area should be stable and reliable, and away from any heat sources.


1-10 Version: A

The cables' bends and branching elements should be kept in a proper order; that is, they should be arranged neatly without crossing or twisting. Any bends in the cable should be smooth and without any kinks. The power cable should be a single piece. Avoid connecting or welding two cables to form a longer one.

In laying cables, it is better to lay, arrange and secure them one by one.

Cable labels should be clear and in order.

The measured value of the working environment temperature and humidity in the equipment room is the value that measured at the point that is 1.5m above the floor and 0.4m in front of the cabinet when there is no protection board either in front of or behind the cabinet. The measured value should meet the following requirements:

Temperature range: 0 to +45.

Relative humidity range: 10% to 90%.

Dust-proofing requirements

Dust falling inside the equipment room on the cabinet body will cause electrostatic adherence, which reduces the service life of the equipment and easily leads to the equipment failure. Therefore, users should control the density of dust particles inside the equipment room. Under static condition, the number of dust particles that are larger or equal to 0.5m in one liter of air should be less than 18,000. The following anti-dust procedures are suggested:


Version: A 3-9

The door and the windows should be completely airtight.

Use dust free material for the floor, wall surfaces and ceiling of the equipment room.

Clean the equipment room and anti-dust screens on the equipment regularly.

Don shoe covers and ESD protection clothing before entering the equipment room. Keep the shoe covers and ESD protection clothing clean and frequently replace.

ESD protection requirements

Electrostatic induction is usually caused by the external electric field such as high voltage transmission line and lightning, as well as internal systems such as interior environment, material of the floor and equipment structure. Contact between the operation and maintenance engineers and the equipment may also bring the static electricity on human body to the equipment.

In order to eliminate the harmful effects of ESD, users should take the following measures:

Flooring material: Lay an ESD protection raised floor and provide adequate earth grounding for the floor. The electric resistance of an ESD protection raised floor should comply with the Technical Specifications on Access Floor in the Equipment Room of Computers. When there is no access floor, lay static electrically conductive floor (volume resistivity: 1.0107 to 1.01010). Static electrically conductive floor and access floor both should have electrostatic grounding. They should be connected with the earthing device via a current-limiting resistance of 1M and an earth ground cable.

Caution: Do not use wooden floor, fur, flax, chemical fiber carpet or plastic flooring.

Ceiling material: Choose ESD protection materials. Plasterboard is allowed under normal circumstances; common plastic material is prohibited.

Wall surface material: Choose ESD protection wallpaper. Painting the wall with plaster or lime is allowed under normal circumstances. Do not use normal wallpaper or plastic wallpaper.


3-10 Version: A

There should be a mark for ESD protection in the equipment room.

Operation and maintenance engineers should be required to wear an ESD protection wrist strap while working. The ESD protection wrist strap should be connected with the ESD protection earth ground fastener on the cabinet, so as to achieve good grounding.

Electromagnetic radiation protection requirements

The electric field intensity of the equipment room is suggested to be less than 126dB and the magnetic field intensity less than 800 (A/m). Usually, users should take the following electromagnetic radiation protection measures:

Keep away from the high-voltage transmission lines, high-power equipment and high-power broadcast transmitters.

Shield the interference source of electromagnetic radiation.

In order to achieve good EMC restriction, the building where the equipment room is located should have comprehensive grounding standards and connect the ground network with legible ground marks.

Do not use handheld wireless communication devices near the equipment in the equipment room.

Air conditioning and ventilation

In order to meet the operating room requirements, users should install air conditioners and ventilators in the equipment room.

Caution: The equipment room should be equipped with an air conditioner that operates all year round. The air-conditioner should be appropriately positioned so that it will not blow directly on the equipment.

3.4.5 Equipment Room Power Supply

The equipment room should provide power supply outlets and meet the requirements for construction. The power should meet the equipments needs and provide adequate margin. The equipment room power cabinet should be equipped with adequate connectors.

AC power supply requirements

The major AC power supply should be the AC mains supply. In order to guarantee reliable communication, besides the AC mains supply, a diesel-engine generator may also be equipped as the standby power supply. For increased reliability the equipment should be supplied with redundant power rails.

DC power supply requirements

DC power supply system includes storage battery, rectifier and DC power distribution equipment. The nominal DC working voltage is -48V, the variation range allowed is -57V to -40V. The DC power supply should have over-voltage and / or over-current protection.

3.4.6 Lightning-proofing and Grounding

Recently constructed equipment rooms usually use a combined grounding scheme. In a combined grounding scheme the AC ground, DC ground, protection earth ground, lightning-proofing earth ground of all communication equipment share one set of grounding bodies. Below are the general requirements:

The ground resistance should be less than 5. The ground cables are arranged independently and cannot form an electrical

path via a connection between construction bars or form a path via cabinet racks.

Ensure that the ground cable and the ground bar in the equipment room are well connected.

The equipment room should be equipped with lightning rod or a lightning protection network in geographical areas that are subject to lightning strikes.


3-12 Version: A

The ground body of lightning conductor and lightning arrester are designed in a radial pattern or a ring pattern.

The cabling racks, iron hanging racks, cabinet racks or shells, metal ventilation ducting, metal doors and windows should have protection earth grounds.

3.4.7 Supporting Facilities

Relevant supporting facilities are available, including the MDF, ODF, and DDF.

Supporting facilities have adequate terminals and are normally connected.

The construction site is equipped with essential tables and chairs, telephone for communication, AC power supply socket for construction and so on.
