Paper knife

Background Information Generally, the board has been installed in the subrack properly before delivery and is shipped together with the subrack. If a carton is used to pack boards for shipping, unpacking and checking are necessary when the boards arrive at the destination. (Generally, a carton is used when boards are required for capacity expansion.) The boards are put into shielding bags for transportation. Take ESD protection measures when you unpack the boards to prevent damage to them.

Precautions

CAUTION Electronic circuits and components are extremely sensitive to electrostatic discharge (ESD). When handling circuit boards, make sure that you wear a securely grounded ESD wrist strap or ESD gloves, and only hold the edge of boards during operation.

Procedure Step 1 Wear a securely grounded ESD wrist strap(or ESD gloves) and make sure that it is securely grounded. Step 2 Cut the straps with diagonal pliers and use a paper knife to split the tape along the seam between the cover and the box body. See Figure 1-7.

CAUTION Do not cut too deep into the carton with the paper knife. Otherwise, the knife might scratch the articles inside.

Installing and Routing Fiber Jumpers

About This Chapter The fiber jumpers are divided into internal fiber jumpers and external fiber jumpers. Internal fiber jumpers are used for connecting optical interfaces within a cabinet. External fiber jumpers are used for connecting optical interfaces of a cabinet to those of other cabinets or peripherals. NOTE

Before you install the fiber jumpers, remove the front door and side panels of the cabinet. Assemble the front door and side panels after the fiber jumpers are installed.

6.1 About Fiber Jumpers Based on the cable types, the fiber jumpers that the OptiX 155/622H uses are classified into two types, which are 2 mm single-mode and 2 mm multi-mode fiber jumpers. Based on the connector types, the fiber jumpers that the OptiX 155/622H uses are classified into three types, which are the fiber jumpers with SC, FC, and LC connectors. 6.2 Installation Procedure This section describes how to route and install the external fiber jumpers. A corrugated pipe or winding pipe is required to protect the fiber jumpers between the cabinet and the ODF during the cabling. 6.3 Checking the Installation After the fiber jumper is installed, check whether the fiber jumper installation is correct.

Table 9-7 Requirements for lightning protection and grounding

9-10

Item

Description

On structure of the equipment room

Build the equipment room with steel and concrete. The equipment room should be equipped with facilities such as a lightning arrester to protect it against direct lightning strokes. Make sure that the lightning protection grounding of the equipment room, or that of devices such as the lightning arrester, shares the same grounding body with the protection grounding of the building where the room is located.

Use TN-S for AC power supply

Equip the communication office with special electric transformers and a metal-jacketed or insulation-jacketed power cable. The power cable should pass through a steel pipe and should be buried in the earth before entering the office. Both ends of both the metal jacket and the steel pipe should be grounded properly. Make sure that the cable is buried not less than 15 meters deep. Each of the three live cables at the low-voltage side of the AC transformer should be equipped with a gapless zinc oxide arrester respectively. The chassis, the AC neutral cable of the lowvoltage side, and the metal jacket of the cable connected to the chassis should be grounded properly.

Equip the incoming power cable with a lightning arrester

Do not lead in or lead out AC/DC power cables aerially for the office. Equip the in-room low-voltage power cable with a lightning arrester in the voltage regulator or in the AC panel. The arrester should be grounded proximately. If the office is located in the city, it is recommended that you use an arrester with the nominal discharge current of not less than 20 kA. If the office is located in the suburb of intermediate lightning danger level or higher, an arrester with the surge current higher than 60 kA is recommended. If the office is located in an isolated huge building in the city or in the mountain area where lightning occurs often, use an arrester that has a surge current of more than 100 kA. The grounding cable should be less than 1 meter long.

DC power supply grounding

The working ground of the office, that is, the anode of a -48 V DC power supply or the cathode of a 24 V power supply, should be led from the indoor grounding bus line properly. The grounding cable should meet the requirement of the maximum load of the equipment. The power supply facilities for the office must contain a DC working neutral line, which is connected from the general grounding bus line or the protection grounding bar of the equipment room.

Equipotential connection

All communication equipment and auxiliary equipment in the room, such as the mobile base station and the transmitting, exchanging, power and distribution frame should be connected to the protection ground. The protection grounding of all equipment in the communication office should share the same general grounding bar, whereas the protection grounding of the same equipment room should all connect to the same protection grounding bar. The working ground and protection ground of the communication equipment in the equipment room should adopt the joint grounding mode, that is, they share the same grounding network. Protection grounding measures should also be taken for the indoor cable rack, equipment chassis, metal ventilation pipe, metal door or window.

Item

Description

General requirements on grounding

The AC neutral line must not be connected to the protection ground of any communication equipment. Make sure that there is no fuse, switch or other similar devices on the grounding line. All grounding lines should be as short and straightforward as possible. Take measures to prevent them from being wound

On the grounding resistor

< 1 ohm. The upper end of the grounding body should be 0.7 meters or more underground. In cold areas, the grounding body should be buried in the frozen layer or lower. Make regular monitor efforts on the grounding resistor to make sure the grounding is always valid.

On routing of the signal cable

Signal cables should be led into the communication office from underground. Aerial routing of signal cables is not permitted. The leadin or leadout communication cable should be metal-jacketed. Otherwise, they should be routed in metal pipes. The grounding cable of the arrester should be as short as possible. The empty pairs in the cable should be connected to the protection ground in the equipment room.

On the grounding bus line

The general grounding bus line can be grounding loop or bar. The grounding cable should not contain aluminum material. If an interconnection occurs between different metal connectors, take measures to avoid by electric chemical corrosion. Generally, the crosssectional area is a copper bar of not less than 120 mm2 or zinc-plated flat steel of the same resistance. The grounding bus line should be kept insulated from the construction steel.

On the grounding lead-in wire

The grounding lead-in should not be longer than 30 meters. In addition, it is recommended that you use zinc plated flat steel with the crosssectional area of 40 mm x 4 mm or 50 mm x 5 mm.

9.10 Power Supply This section describes the DC power supply system. The working power voltage for the equipment ranges from –38.4 V to –57.6 V. The transmission equipment offers a transmission path for communication networks, and thus its interruption will have a wide influence. Therefore, the DC power distribution system should be protected against power failure and configured with storage batteries. To deal with a long-term power outage, a diesel generator should be equipped as the standby AC power supply for the backbone transmission equipment. The DC power supply system consists of storage battery, primary power supply (rectifier), DC distributor and control panel.

Storage battery The storage battery is an essential component of the DC power distribution system of the OptiX equipment functionally. It has the following functions: l

Issue 02 (2008-09-10)

9 Operation Environment Requirements l

Stores energy. In the case of outage of mains, the storage battery can feed power for a period of time, which depends on its capacity, so that the communication will not be interrupted immediately.

l

Filters for large capacitors. The storage batteries are useful for absorbing surge voltage from rectifiers and preventing noise and power frequency interference from getting into the communication equipment.

l

Automatically shuts down. When the voltage of the storage battery drops to below –43 V, the control circuit can automatically shut down the output.

DC distributor and control panel l

The capacity of the primary power supply should be designed according to the power consumption of the transmission equipment of the terminal office, and a certain margin should be reserved. Generally, high frequency switching power supplies with a high switching efficiency should be adopted, which should work in N+1 hot standby mode. There should be an output current equalizer for each power module. The failure of a single power module will not affect the normal operation of the whole DC power distribution system.

l

Each control panel can access a minimum of two groups of storage batteries. When one of them fails, the other can supply power instead.

l

Each control panel can access a minimum of 5 primary power supplies.

l

The power supply equipment should be capable of automation, so as to satisfy the nonattendant requirement.

primary power supply becomes faulty, it will drop out automatically, while the standby primary power supply will automatically go into operation. l

In the case of mains outage, storage batteries will discharge. When the mains resumes, it will automatically recharge the discharged storage batteries with a current 0.1 to 0.15 times of the battery capacity. When the charging voltage reaches 56.4 V, it will automatically change to constant-voltage charging.

l

When the storage batteries are fully charged, they will automatically change to floating charge.

The OptiX optical transmission equipment also has critical restriction on random transient noises, which include the abnormal operation noise of the equipment caused by external magnetic interference and the interference from the equipment itself and the grounding cables. The shorter the duration of the transient pulse, the higher values of such transient noises can be allowed. For the allowable values, see Figure 9-3. Figure 9-3 Transient noises

l

When the power supply equipment fails or works abnormally, visual and audible alarms should be given. Such alarm information should be able to be sent to the operation and maintenance center.

l

In case short circuit occurs to a tributary of the power supply system, the whole power distribution system should not be affected by the sharp voltage reduction. And the peak striking voltage should not cause any breakdowns to the transmission equipment.

Suggestions for Basic DC Power

9-14

l

The distributed power supply mode is recommended. That is, it is recommended that you adopt multiple DC power supply systems or locate the power supply equipment at different places.

l

Adopt the DC power supply systems that comply with the relevant standard, and set the output voltage of the communication power supply system to be within the required voltage range.

l

To improve the reliability of the power supply systems, improve the reliability of the AC power supply system and reduce the capacity of the storage batteries to a proper value. If difficulty exists when you improve the reliability of the AC power supply system, increase the capacity of the storage batteries to a proper value.

l

The total capacity of the high-frequency switch rectifier should meet the requirements for the input of the communication load power and the charging power of the storage batteries. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

Issue 02 (2008-09-10)



Redundant rectifier modules are required. If there are not more than 10 working rectifier modules, there should be one protection rectifier module. If there are more than 10 working rectifier modules, one protection rectifier module is required for each 10 working rectifier modules. l

The storage batteries should be installed as two groups or multiple groups. The total capacity of the storage batteries depends on the time during which the storage groups feed power to the load independently. In normal communication stations, a storage battery group should be able to feed power for at least one hour.

9.11 Lighting in the Equipment Room The OptiX transmission equipment room is equipped with three lighting systems. l

Active lighting system, which is powered by mains supply.

l

Backup lighting system, which is powered by backup power supply (diesel electric generator) of the office.

l

Emergency lighting system, which is powered by storage batteries when the mains supply has been interrupted but the backup power supply has not yet started to supply power.

9.12 Protection System This section describes the requirements for the protection system.

ESD protection The equipment-affecting electrostatic induction comes from the external electric field such as outdoor high voltage transmission line or lightning. It also comes from the internal system such as indoor environment, floor materials or equipment structure. Static electricity may damage the chips on integrated circuit boards and cause faults in software and electronic switch. Statistics shows that 60 percent of the damaged circuit boards are caused by static electricity. It is essential to take effective ESD protection measures. The following measures are recommended: l

Ground the equipment well. While laying the raised floor covered with semiconductive materials, copper foil should be used for grounding at a number of points on the floor (the copper foil should be placed between the cement ground and the semiconductive floor and should be connected to the grounding cable).

l

Take dust-proof measure. Dust may do great harm to the optical synchronous transmission equipment. Dusts or other particles getting into the equipment room may cause poor connection between connectors or metal connecting points. When the humidity in the room is high, dust can cause electrical leakage. It is found in maintenance that the equipment failure is often caused by accumulated dusts. Especially, when the humidity in the room is very low, electrostatic adherence is likely to occur.

l

Keep proper temperature and humidity. Too high humidity may make the metal components rusty, while too low humidity may induce static electricity.

l

Always wear an ESD-preventive wrist strap and lab coat when touching a circuit board to prevent electrostatic damage to the equipment.

Interference prevention With the development of technologies and social economy, more and more electromagnetic signals are transmitted in the air. They may affect the communication quality by causing crosstalk and stray noise, and even result in communication interruption. The electromagnetic interference (EMI) sources include: l

The corona discharge of the electric transmission line

l

The transformer

l

Switches

l

Waveform distortion of the power supply network caused during the operation of large equipment

l

Radio frequency (RF) interference

l

Natural interference sources such as terrestrial magnetic field and external radiation

The interference, from either inside or outside the equipment or the application system, affects the equipment through conductive modes such as capacitance coupling, inductance coupling, electromagnetic wave radiation, common impedance (including grounding system) and cable (power and signal cables). In terms of external relations of the equipment, interference is from the signal cable, power cable, grounding system and spatial electromagnetic wave. Integrated circuits (ICs) have the interference resistance capability to a degree. However when the external noises go beyond their anti-interference tolerance, corrupted signals and even system malfunction will be caused. It is impossible to eliminate or shield all the interference sources, but the following measures can be taken to suppress the interference signals:

9-16

l

High frequency interference in the power supply network is generated when the primary coil of the power supply transformer is coupled to the secondary coil through distributed capacitors. To suppress such interference, we can use an appropriate transformer, and install a low-pass filter at the inlet of the power supply cable.

l

The interference of the transient voltage in the power supply network can be reduced by inputting power directly from the primary transformer with a filter capacitor for the optical synchronous transmission equipment.

l

When the optical synchronous transmission equipment works in the 50 Hz mains power supply network with the above interference, the surge voltage caused by the power supply network and the over-voltage generated by lightening will be passed to the power supply of the optical synchronous transmission equipment, which leads to computing errors of the processors. Therefore, before directly using the mains supply, effective measures against interference from power supply network should be taken.

l

The key to eliminate the interference from the grounding system is to avoid loops among various grounds, such as the signal ground (including analog and digital grounds), BGND, PGND and shield ground, or loops formed by large distributed capacitors. Otherwise, the common impedance interference from the grounding system may affect the operation of the equipment. In buildings other than high-rises, the working ground of the optical transmission equipment should be separated as far as possible from the ground for electricity equipment and lightning protection device.

l

Prevent electromagnetic radiation interference from the surroundings to the equipment. In some integrated communication buildings, if there is a high frequency transmitter there, its influence on the optical transmission equipment should meet the relevant requirements. Independent power supplies are recommended for them.

l

EMI from the telecommunications line should be restrained. Influenced by high frequency electromagnetic field (external interference), high longitudinal voltage will occur to the Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

Issue 02 (2008-09-10)



core and sheath of the communication cable. Because of the asymmetry of cores in the cables, the longitudinal voltage will generate a horizontal noise voltage at the ends of the cores. When both ends of the cable sheath are grounded, the sheath will function as a shielding layer, greatly reducing the longitudinal voltage and reducing the interference voltage. Other effective methods include: reduce the voltage or current of the interference source; reduce the line length and the spacing of the conducting wires to reduce the area of the affected loop; directly place the insulated conducting wires on the grounded floor; use a special grounding feedback cable to avoid co-impedance; or twist the signal cable and the feedback cable together to offset partial peripheral electromagnetic interference, and so on.

Fire protection For small equipment rooms, a certain number of portable fire extinguishers should be equipped in each room for an initial fire control. In large equipment rooms, fire extinguishing facilities should be equipped. An automatic fire alarm system should also be equipped in the equipment room. All telecommunication buildings with fire alarm system should have fire emergency lighting system and evacuation instruction marks at important places, paths and gateways.

Anti-earthquake demand The designed anti-earthquake intensity of the telecommunication equipment room must be one degree (Richter scale) higher than that for the common buildings. The equipment room building that cannot meet the requirement should be reinforced. When installing the OptiX optical transmission equipment, the following anti-earthquake measures should be taken. l

Use steel framework for the cabinet of the equipment. There are locking devices to fix the boards in the cabinet.

l

The cabinet is reinforced with slide rail on the top and supports at the bottom.

Lightning protection Chimneys, antennae or other things that are over 15 m tall on the top of the equipment room building should be designed according to the lightning protection requirements for civil buildings. Measures should be taken against direct flash and intrusion of lightning current. In the main high-rise transmission building, protective measures should be taken to prevent side lightning strokes, especially in frequent lightning areas. Therefore designers should take actual conditions into consideration and take appropriate measures. For example, connect the metal external window frame to the lightning protection wire; along the height of the building, place the lightning protection metal bands at a definite spacing on the outside wall, and so on. The main equipment-room building should be provided with the following lightning protection measures: l

Issue 02 (2008-09-10)

The building should be installed with lightning arrester nets or bands at the positions susceptible to lightning strokes. Lightning prevention wires or lightning rods should be installed on the top of chimneys and antennas that are protruding from the building. The cross-sectional area of the grounding wire of the lightning protection device should not be smaller than 2 mm2, while the space between the wires not larger than 30 m.


9-17



l

The earth resistance of the earthing/grounding system is recommended to be less than 10 ohms, and the equipment grounding should be in accordance with national and local electrical codes as well.

l

Outdoor cables and metal pipes should be grounded before entering the building, and the outdoor overhead cables should be equipped with lightening protection devices at the inlet of the building.

l

It is suggested to use roof plates, beams and pillars made of reinforced concrete and the reinforcement bar as the ground wires of lightening arresters.

In the past lightning protection grounding of the building was separate from the grounding for telecommunication system and power supply system, and a large distance was required between the grounding objects. However, the distance requirement is not satisfied due to small space of the building. In fact, they cannot be separated in most cases, so joint grounding system is recommended for the lightening protection grounding of the building. The joint grounding system shall connect the telecommunication BGND, PGND, lightning protection grounding of the building, and grounding of the power frequency AC power supply system. A high earth resistance of the joint grounding system is required. The earth resistance required by telecommunication is far lower than 10 ohms, and the grounding requirements for different telecommunication devices vary, so the resistance of the joint grounding system should be determined according to the minimum resistance required for the grounding device. It is recommended to use steel bars in the walls and pillars of the building as ground wires for lightening protection. These wires should be electrically connected so as to equalize the electric potential in the building.

The Requirements of Cabling and Bundling

About This Chapter Introduces the requirements of cabling and bundling the cables. 11.1 The Requirements of Cabling Describes the method and requirements of cable routing. 11.2 The Requirements of Bundling Describes the method and requirements of cable binding.

Issue 02 (2008-09-10)


11-1



11.1 The Requirements of Cabling Describes the method and requirements of cable routing. l

For equipment room installed with supports and ESD protection floor, cables can be arranged in downward mode. That is, all cables can be routed through the interlayer of the floor or the cable trough. If the upward cabling mode is adopted, cabling rack is required above the cabinet for holding cables.

l

The specifications and cross-sectional area of the cable, and the route and position for cabling should be designed beforehand.

l

All cables should be arranged neatly, with their sheaths remaining intact.

l

Communication cables, such as alarm cables, network cables and clock cables, should be arranged separately with the power cable and optical fibers.

l

Turnings of the cable should be smooth, with the bend radius reaching 60mm or above.

l

Any damage to the insulation layer of the conducting line is not allowed.

l

The cable arrangement should take the future maintenance and capacity expansion into consideration.

11.2 The Requirements of Bundling Describes the method and requirements of cable binding. l

Bundling of the cable should be tidy, clear and elegant. As a general rule, cables are grouped by types, or grouped as needed when they are in a large number. Bind them with cable ties and route them in either upward or downward cabling mode in the cabling area at the two sides of the cabinet.

l

Cables must be bundled when arranged in ducts. Bind the cables closely with appropriate tightness. The space between the cable ties should be even and the overall appearance of the cabling nice.

l

You may not bind the cables when arranged in cable troughs. But they should be placed tidy and straight in the trough with no crossover. Moreover, the cables can not overflow the trough. At two ends and turnings of the trough, use a plastic clip for the cables.

l

Cables both inside and outside the cabinet must be bundled. Keep the cables bundled closely and neatly.

l

Use cable ties of different specifications for cables according to actual circumstances.

l

Do not connect two cable ties in bundling. Otherwise, the binding strength will be weakened.

l

After the bundling, cut the remaining part of the cable tie smoothly, removing all burrs.

l

The space between the cable ties is even and is three or four times the size of the bundle diameter.

l

When making turning for the bundled cable, keep the bend radius as big as possible to avoid breaking the cable cores at the turning.

Figure 11-1 shows the specific operation of bundling.

Engineering Labels

About This Chapter Engineering labels are affixed to both ends of various cables to identify the physical positions of cables on different devices. There are two types of engineering labels, specialized for the power cables and signal cables respectively. The power cables include –48 V / –60 V power cables, power ground cables (BGND) and protection ground cables (PGND). The signal cables include external alarm cables, network cables, clock cables, optical fibers and so on. Engineering labels for cables ensure the orderly and correct installation of cables of equipment and facilitate the easy subsequent equipment maintenance and inspection. NOTE

In case there is special requirement from the user of the equipment on the description method of the labels, the labels should be printed accordingly. However, this must be stated in the self-check report.

12.1 Introduction to Labels Introduces the labels used in the equipment. 12.2 Information Carried on Labels This section gives the information carried on labels for signal cable and power cable. 12.3 Filling Information on Labels This section describes how to fill information on labels. The contents can be printed or written on the labels. Printing is recommended for the sake of high efficiency and eye-pleasant layout. 12.4 Affixing Labels After printing or writing the label, remove the label from the bottom page and affix it to the signal cable, or the identification plate of the power cable. 12.5 Common Engineering Labels This section describes the common engineering labels. The other labels are omitted in this part. You can perform the operation as required on site.

Seen from the cabling end of the equipment, the text part of the label is on the right side of the cable. The side with "TO:" that is facing outside carries the location information of the opposite end, and the other side carries the location information of the local end. Therefore, the information in Area 1 at one end is the same as the information in Area 2 at the other end of the cable, and vice versa. In other words, the local information at one end is called the opposite information at the other end.

12.2.3 Remarks To use labels, focus on the following points. l

When printing/writing and affixing labels, pay attention to keep the labels clean.

l

Since the label paper is made of moistureproof and waterproof material, ink-jet printers and ink pens are forbidden for printing and writing labels.

l

Labels should be affixed with good order in alignment.

l

Cable ties should be bundled in the same position of power cables, with identification plates on the same side.

l

The positions of "up", "down", "right" or "left" are all based on the viewpoint of the engineering person who is working on the label.

12.3 Filling Information on Labels This section describes how to fill information on labels. The contents can be printed or written on the labels. Printing is recommended for the sake of high efficiency and eye-pleasant layout. 12.3.1 Printing Labels Use a laser printer to print the label according to the template. 12.3.2 Writing Labels Use the black oiliness markers delivered together with the equipment to write the labels.

The labels for DC power cables are affixed to one side of the identification plates on cable ties. 12.5.2 External Alarm Cables The external alarm cables are connected to the first subscriber cabinet of each row (used for power distribution). Labels posted on the first cabinet of each row should indicate which equipment is using the access terminal. 12.5.3 Ethernet Cables 12-10


Issue 02 (2008-09-10)



The engineering label of the Ethernet cable is affixed to identify the Ethernet cable of the network port on a board. The label contains the following information: cabinet number, frame number, location number, physical slot number, and Ethernet port number. 12.5.4 Fibers Between Two Devices These labels are affixed to the fiber jumpers that connect the optical interfaces on the boards in a frame or on the device boxes. There are two types of labels for fiber jumpers: one is for the fiber that connects the optical interfaces on two devices, the other is for the fiber that connects the device and the ODF. 12.5.5 Fiber That Connects the Device and the ODF The label stuck on the fiber from the equipment to the ODF contains all necessary information on the cabinet and the ODF. 12.5.6 Trunk Cables The trunk cables include 75-ohm/120-ohm E1 cables, 120-ohm T1 cables, 34 Mbit/s, 45 Mbit/ s, 140 Mbit/s, 155 Mbit/s cables and 120-ohm to 75-ohm trunk cables, and clock cables. 12.5.7 Subscriber Cables The labels are affixed to both ends of the subscriber cables to identify the position of the cables on the device side and the main distribution frame (MDF) side.

12.5.1 Power Cables The labels are affixed to the DC cables that provide power for the cabinets, including the –48 V, PGND, and BGND cables. The labels for DC power cables are affixed to one side of the identification plates on cable ties. Table 12-2 provides the information carried on the labels for the DC power cables. Table 12-2 Information on labels affixed to the DC power cables Content

Meaning

MN(BC) - -1

MN (BC): BC is written right under MN. On the loaded cabinet side, MN identifies the row and column number of the power distribution equipment such as the control cabinet and distribution box; BC identifies the row and column number of the –48 V connector (if there is no row number or column number, or the connector can be identified without them, BC can be omitted). BGND and PGND have no row and column number for identification. On the power cabinet side, only MN is used to identify the cabinet.

MN(BC) - -2 MN(BC) - BGND MN(BC) - PGND

The label only carries location information about the opposite equipment, the control cabinet, or the distribution box. The information of the local end is not necessary. Table 12-2 lists the information of two –48 V power supplies on the label. The information for other DC voltages (such as 24 V, 60 V) should be provided in similar methods. Make sure that labels are affixed in correct direction. That is, after the cable ties are bundled onto the cable, the identification plates with the labels should face up, and the text on the labels in the same cabinet should be in the same direction, as shown in Figure 12-9.
