laser with high power.

Looking into or near the end face of the optical fiber directly with naked eyes may

injury eyes. To prevent laser radiation from injuring eyes, keep your eyes away from

the end face of the optical fiber or damaged optical fiber for more than 150mm. Eyes

may be injured by observing the naked end face of the optical fiber from optical

instruments, such as microscope, magnifier and loupe.

Security measures

Operators should abide by the following requirements, so as to avoid laser damage.

u Operators must obtain the necessary qualification about laser safety.

1-8 Version: A


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

laser.

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

before you ensure that the optical source is switched off.

u Use an optical power meter to check and ensure that the optical source is

switched off by measuring the optical power.

u When handling or near a laser, do not wear reflective objects as jewelry and

watches to prevent accidental eye injury.

u Before cutting or splicing optical fibers, ensure that the fibers are disconnected

from the optical source.

1.6 Other Safety Precautions

Plugging / Unplugging a Card

u 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.

u Prevent the circuit surfaces of cards from contacting each other, to avoid

shorting or scratching.

u 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.

u Do not plug or unplug the card while it is powered.

Binding Cables

u 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 should be bound with dedicated cable ties.

u After completing the equipment installation, do not adjust the position of the

equipment or cables.

Version: A 1-9


Laying Cables

u If the temperature is too low to allow proper cable handling, measures should

be taken to warm cables before handling.

u 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.

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

sources.

u The cables' bends and branching elements should be kept in a proper order

and 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.

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

u The labels on the cables should be clear and complete.

u Temperature range : 0℃ to 45℃.

u Relative humidity: 10% to 90%.

3-8 Version: A


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 0.5μm in one liter of air should be less than 18,000. The

following anti-dust measures are recommended:

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:

u 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 Specification for Raised Floor of Computer

Rooms. When the access floor is not installed, lay the static electrically

conductive floor (volume resistivity: 1.0×107Ω·cm to 1.0×1010Ω·cm). Static

electrically conductive floor and access floor both should have electrostatic

grounding. They should be connected with the ground cable and ground

equipment via a current-limiting resistance of 1MΩ.

POTN series of products.

Requirements for Layout of Wires and Cables

Preparing for Cable Arrangement

Introduction to Wires and Cables

Connection and Layout of Internal Wires and Cables

Connection and Layout of External Wires and Cables

Version: A 7-1


7.1 Requirements for Layout of Wires and Cables

Layout Principles of Wires and Cables

u The specifications, routes, cross-sectional area, and position of the cables

arrays should comply with the construction plan drawing. Take future

maintenance and capacity expansion into account when arranging the cables

and connecting the ports.

u When arranging the cables on the floor, keep the floor clean and smooth. A

dirty or rough floor may contaminate or damage the insulating sheath of the

cables.

u Arrange the cables in good order, without damaging their insulating sheaths.

Do not drag or draw the cables forcibly.

u Arrange the AC/DC power cables and the signal cables separately in different

bundles. If they cannot be arranged in different routes, leave an interval of more

than 5cm between them.

u The optical fiber jumpers should be arranged last to prevent them from being

kinked, bent excessively or pressed.

Wiring Principles of Wires and Cables

u If the equipment room is equipped with wiring channels mounted under an ESD

protection raised floor, installers can use the floor access wiring mode. In this

mode, wires and cables enter via the wiring holes at the cabinet bottom from

the channel under the ESD protection raised floor.

u If the equipment room is equipped with the upper support channels, installers

can use the top access wiring mode. In this mode, wires and cables enter via

the wiring holes at the cabinet top from the upper support channel.

u Arrange the wires and cables in the wiring channels located on both inner sides

of the cabinet and pass through the wiring holes.

Bending Principles of Wires and Cables

u To prevent the cable cores from being damaged, do not apply too much force

when bending the cables at the corners.

7-2 Version: A

7 Connection and Layout of Wires and Cables

u The bend radius of the optical cable should not be smaller than 20 times the

optical cable’s external diameter.

u The bend radius of the electrical cable should not be smaller than 5 to 10 times

the electrical cable’s external diameter.

Layout principles for power cables

u With the premise that the cables must be arranged in compliance with the route,

the power cables (including protection earth ground cables) should be

processed on site according to the “shortest” route principle.

u The power cables should be made of a continuous segment of copper core with

no intermediate connections.

Layout Principles of Optical Fibers

u Protection measures, such as using corrugated conduits or channels, should

be used when the optical fibers are routed outside the cabinet.

u Take the fragility of the optical fibers into consideration when arranging optical

fiber jumpers. The bend radius of optical fibers should be no less than 38mm.

u To prevent laser radiation from injuring the eyes, never look at the end face of

the optical fibers directly during handling.

u The fiber connectors that are not in use should be protected by the anti-dust

caps.

Principles of Binding Wires and Cables

u After arranging the wires and cables in the fiber passage units, use the binder

to stabilize the wires and cables carefully, but do not bind the fiber pigtail

excessively.

u You should not bind the cables when they pass the wiring channel; make the

cables inside the channel neat, without crossing or twisting them. Always keep

the cables within the channel.

u Secure the cables near the entrances of the channels and at the corners with

the correct binding method.

Version: A 7-3


u Bind the cables with wire binders carefully at equal intervals with appropriate

tightness; and the bound cables are arranged close to each other in good order,

without crossing or twisting. See Figure 7-1.

Figure 7-1 Binding of Straight Cables

u Cables coming out from connectors should be bound in order. Do not cross or

twist them, as shown in Figure 7-2.

Figure 7-2 Binding of Lead-out Cables

u Installers should cut all sharp points at the ends of cables. Arrange all wire

binders in the same direction. See Figure 7-3.

Figure 7-3 Arranging the Wire Binders

u When binding the bent cables, do not bind them midway through the bend;

otherwise, it will break the cores inside the cables. Figure 7-4 shows the proper

binding method.

7-4 Version: A


Figure 7-4 Binding of Bent Cables

u The principle of arranging the cables inside the cabling rack is: the shorter the

cable is, the higher the location is. Figure 7-5 shows the arrangement method.

Figure 7-5 Arranging Wires and Cables

Version: A 7-5


7.2 Preparing for Cable Arrangement

Before cable arrangement, make sure you have done the following:

u Remove the front panel of the PDP ( for some PDPs, remove both the front

panel and the bottom baffle). After arranging the cables, restore the front panel

(and the bottom baffle) to its original place.

u Remove the nylon screen or the plastic board covering the wiring holes for inlet

and outlet on the cabinet for convenience of cable arrangement.

7.3 Introduction to Wires and Cables

u The internal cables are the wires and cables that are connected inside the

cabinet. They are usually connected before delivery.

u The external cables are wires and cables that connect the equipment and other

devices outside the cabinet. They are usually connected on site.

See Table 7-1 for the classification of wires and cables.
