z

Be sure to turn off power before installing and removing power cables.

z

Before connecting cables, make sure that the cables and cable tags are correct.

3.3 Fuse

Caution: Never install or remove electrified fuses.

z

Only technicians qualified for high-voltage operations can install or remove fuses.

z

Be sure to switch off power before replacing AC fuses.

3.4 Tools

Warning: High-voltage and AC operations call for special tools instead of general-purpose or makeshift tools.

3.5 Drilling Holes

Warning: Do not drill on the cabinet at will. Improper drilling may damage cables inside the cabinet. The metal filings resulting from the drilling may fall into the cabinet and short-circuit the circuit board. z

Wear insulated gloves and move away the cables inside the cabinet. Huawei Technologies Proprietary 5


Safety Precautions

z

Protect your eyes from flying metal filings.

z

Prevent metal filings from falling into the cabinet.

z

Drill at proper places to avoid affecting the electromagnetic shielding performance of the cabinet.

z

After drilling, remove all the metal filings at once.

3.6 Thunderstorm

Danger: Never work on high-voltage and AC or work on steel towers and masts in thunderstorms.

Thunderstorms generate powerful electromagnetic fields in air. Ground the equipment properly to avoid thunder stroke.

3.7 Static Electricity

Caution: Static electricity generated on human body may damage the electrostatic-sensitive parts on the circuit board, such as large-scale integrated circuit (IC).

z

In dry climate, the electrostatic charge carried by the human body may be up to 30 kV. The charge may remain on the human body for rather a long period. When an operator with electrostatic charge contacts a part, the electric discharge may damage the part.

z

Before contacting any equipment, hand-held plug-in boards, circuit boards or IC chips, put on an anti-static wrist strap with one end well grounded to protect sensitive parts from static electricity on your body.

z

Before touching any board or module, discharge the static electricity in your body by wearing an anti-static wrist strap.

z

Add a resistance over 1M between the strap and the grounding point to protect yourself from electric shock. The resistance over 1M is reliable in terms of electrostatic voltage discharging. Check the anti-static wrist strap regularly. Never replace the cable of the anti-static wrist strap with other cables.

z

Prevent electrostatic-sensitive boards or modules from touching the object with static electricity or the object that may easily generate static electricity. For Huawei Technologies Proprietary 6


Safety Precautions

example, when rubbing on an object of insulating materials such as packing and conveyer, an electrostatic-sensitive part takes electric charge. When touching a human body or connect to the ground, the discharge may damage the part. z

Electrostatic-sensitive boards or modules can only contact good conductors, such as anti-static packing bags. Pack the board with an anti-static bag for stock or transport.

z

Before connecting any measurement device to boards or modules, ground it to discharge its static electricity.

z

Do not place boards or modules near strong DC magnetic field, for example, the cathode ray tube of a scope. Keep the distance at 10 cm at least.

z

The damage caused by static electricity is accumulative in effect. If the damage is slight, the part does not fail. However, as the damage occurs repeatedly, the part may suddenly fail. The electrostatic discharging damage on the part may be explicit or implicit. The implicit damage is not visible. However, it makes the part vulnerable to over-voltage and high-temperature.

Figure 1 shows how to wear an anti-static wrist strap. Plug of anti-static wrist strap

Figure 1 Wearing an anti-static wrist strap

3.8 Labels on Power Supply Cables

Attention: Before connecting the cables, check the labels on them.



Safety Precautions

3.9 Leakage Current

Warning: To avoid large leakage current, ground the equipment before powering it on.

Before connecting the AC input power supply, be sure to connect the protection-grounding terminal of the equipment housing with the earth. The purpose is to avoid the electric shock on human body resulting from leakage current. The leakage current is caused by the EMI filter earth capacitance of the equipment AC power supply input terminal and the Y capacitance of the primary power supply.

3.10 Flammable Air

Danger: Do not place the equipment in an environment with flammable, explosive air or smog. Never operate any digital equipment in this environment.

It is extremely dangerous to operate any digital equipment in this environment.

6.5.2 Connecting E1/T1 Cable The DB9 male connector connects to the E1/T1 port of BBU3806, and the SMB female connector to the peer end. Connect the E1/T1 cable by following the principles below: z

The TX end of the trunk cable from BBU3806 must connect to the RX end of the cable from the peer end.

z

The RX end of the trunk cable from BBU3806 must connect to the TX end of the cable from the peer end.

z

Connections between E1 cables from BBU3806 and its peer end depend on specific data configurations.

z

If the trunk cable from BBU3806 is coaxial at 75 ohm and the cable from the peer end of BBU3806 is a 120-ohm twisted pair one, you must connect the two types of cables through an adapter or a transit cable.

6.5.3 Wiring Principles for E1/T1 Cable Route the E1/T1 cable by following the principles below: z

Do not rout the E1/T1 cable overhead outside the equipment room.

z

If the E1/T1 cable has to go outside the equipment room, route them underground through a metal pipe. Ground both ends of the pipe securely.

z

If the E1/T1 cable has to go outside the equipment room and fails to be routed underground, you shall: z

Shield the cable through a metal tube. Ground both ends of the tube

securely. For the section of the cable led into the equipment room, connect it to the protection grounding bar for sound grounding. z

Choose the cable with an outer metal layer. Ground both ends of the metal

layer securely. For the section of the cable led into the equipment room, connect it to the protection grounding bar for sound grounding. z

Ground the idle wire pairs of the E1/T1 cable inside the equipment room. For example, you may connect the idle core wires and shielding layer of the E1/T1 cable to a small metal plate, lead a grounding cable from the plate, and then connects it to the protection grounding bar inside the equipment room.

z

Do not cross the E1/T1 cable with the power cable, grounding cable, and feeder.

z

When routing the E1/T1 cable in parallel with the above three types of cable, keep it at least 30 mm away from any of the cables.

z

Route the cable nicely and neatly, and secure it with cable ties.

z

Make sure the radius of any bent is 20 times larger than the diameter of the cable.




6.6 Installing Fiber 6.6.1 Introduction to Fiber The fiber transmits high-speed CPRI signals between BBU and RRU. There are four LC connectors with identifiers at both ends of the optical fiber numbered as 1a/2a, 1b/2b, 1c/2c, and 1d/2d, as shown in Figure 6-4. (1)

6.6.2 Wiring Principles for Fiber Route the fiber by following the principles below: z

When unpacking fibers, you must check them with the packing list in terms of type, model, and quantity. Classify the fibers by installation position to facilitate future installation.

z

Before installation, check that there is no fold or impress on the fiber and that the connectors are intact. Otherwise, replace it with a good one.

z

Before installation, check that the connectors of the fiber are clean. Otherwise, clean the connectors with a piece of dust-free cotton cloth or a wiping box. For more details, see Appendix D “Cleaning Optical Fiber Connectors”.

z

During installation, do not pull the fiber too tense, jam on the fiber with height foot or any other object, or lay the fiber on sharp objects.

z

If one end of the fiber connects to an optical device, never look straight at the end face of the fiber connector. Otherwise, your eyesight might be affected.

z

When left unused, cover the connector with a protective cap.

z

Make sure the radius of any bent is 20 times larger than the diameter of the cable.

z

Stuff the fiber inlet on the cabinet top with soft matters, for example, fireproof cotton, to avoid possible damage to the fiber.

C.2.4 Printing Labels You can print or write labels. Printing is advisable for high efficiency and eye-pleasant layout.

I. Template for Printing The Word-form template is available for label printout: z

Download the template from http://tech-support.huawei.com/asp/comm/index.asp (path:

//support/technical

document/project

management/installation

and

maintenance/document/others). z

Get the template from Huawei local office.

When using the template, you can directly modify the contents on the template. Be sure to observe the following rules: z

Do not change the settings of centered characters, direction, and fonts.

z

When there are too many characters to fill in, zoom out the characters, but make sure that the printouts are clear and legible.

II. Cells Merging on the Template The procedure is as follows: 1)

Recover the table structure (if gridlines are displayed, you can start from Step 3) directly).

2)

Click [Edit/Select All].

3)

Click [Format/Borders and Shading/Borders]. Select “Box” and click . Huawei Technologies Proprietary C-3


4)


Select the cells to merge and click [Table/Merge Cells].

If two merged cells are still not large enough, use multiple lines.

III. Requirements for Printer Use a laser printer to print labels. Before printing a label, set up the page and try the printing on ordinary blank paper (both sides are blank): 1)

Cover the blank paper onto the whole page of label paper. Check that the page setup conforms to the requirement.

2)

Make sure the printer properties, such as "paper size" and “direction”, have been set correctly.

3)

If the warning prompt as shown in Figure C-3 appears before printing, click to continue the printing.

Figure C-3 Warning prompt before printing If the printout conforms to the requirement, print it to label paper. If not, adjust the page setup and try the printing again until the printout is satisfactory. Adjust the page setup as follows: 1)

Click [File/Page Setup].

2)

Select the [Margins] tab page.

3)

Select “Left” for [Gutter Position].

4)

Set [Header] and [Footer] as 0. Adjust the values of [Top], [Bottom], [Left], and [Right].

When the page setup is correct, save it for future use. The page setup is only necessary for the first time you use the template to print the labels.

IV. Requirements for Feeding Printer No matter what model of printer you are using, feed in paper pieces one after another by hand. Never use the auto-feed mode to avoid jamming the labels. The reason is that the label paper is different from the ordinary paper. It is composed of two pages and processed through many stages.




Different models of printers entail different feeding modes. Be sure to feed in the paper pieces correctly.

V. Requirements for Printed Labels Make sure that the printed labels satisfy the following requirements: All the printout is on the label. Nothing should be printed on the bottom page of the

z

label. Contents in the cells are aligned in the center. In a single-line printout, the dividing

z

lines and the mark “TO:” are not covered by the printed characters. Avoid overwriting the mark “TO:” with contents in merged cells or multiple-line

z

printing. Use the space bar to move the contents to the next line.

C.2.5 Writing Labels Use the black oiliness markers delivered together with the device to write the labels. If have to, you may use black ball-pens instead. In that case, take care not to leave the oil on the label. Note that the oil contaminates the label and blurs the words.

Note: The delivered marker has two nebs. Be sure to use the smaller neb to write the labels.

For easy recognition and good looking, write close to the standard typeface. Table C-1 shows the standard typeface. Table C-1 Standard typeface for handwriting 0

C.2.6 Affixing Labels After printing or writing the label, remove the labels from the bottom page. Affix them to signal cables or the ID plates of the power cables.

I. Affixing Label to Signal Cable 1)

Decide where to affix the label.

Affix the label 20 mm from the connector on the signal cable. To avoid bending the cable or affecting other cables, you may affix the label at other positions. For the vertical cable, affix the label with the text area to the right. For the horizontal cable, affix the label with the text area downward. Figure C-5 shows how to affix a label to a vertical signal cable. The method is similar for affixing a label to a horizontal cable except the cable is 90° clockwise.

Figure C-5 Affixing a label to a signal cable 2)

Fold the narrow part of the label to the right, as shown in Figure C-5-a.




The length of the narrow part is designed for an external cable diameter of 2.6 mm. After this part has been stuck to the back of the label, it may not overlap the entire printed part. 3)

Fold the printed part along the dotted line according to the directions shown in Figure C-5-b.

Figure C-5-c shows the finished label.

II. Affixing Label to Power Cable Remove the label from the bottom page. Affix it to the rectangular flute on the ID plate on the cable tie. Be sure to affix the labels on the same side of the ID plates. Bind the cables with cable ties 20 mm from the connectors. You can change the position to suite actual needs. Bind the cables with cable ties at both ends. After the bundling, the finished ID plate should be on top of the cable in horizontal cabling, or on the right side of the cable in vertical cabling. Make sure that the label is facing out, as shown in Figure C-6.

Figure C-6 Appearance of affixed labels on power cables

C.2.7 Information Carried on Labels I. For Power Cables Affix labels for power cables on one side of the ID plates. On the labels, there is information (the part after the mark “TO:”) about the location of the device at the other end of the cable, such as the location of the control cabinet, distribution box or power socket.




II. For Signal Cables The two sides of the label affixed on the signal cable carry information about the location of the ports connected to both ends of the cable, as shown in Figure C-7. The information is given like this: z

Area 1 contains the location information of this end of the cable.

z

Area 2 (with the mark "TO:") contains the location information of the other end of the cable.

z

Area 3 has been folded up inside the label. Area 1

Area 3

Area 2

TO:

Figure C-7 Printed parts on the label for signal cables 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. 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. In other words, the local information at one end is the opposite information at the other end.

C.2.8 Points for Attention z

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

z

Because the label paper is made of moisture-proof and waterproof material, do not use ink-jet printers or ink pens to print or write labels.

z

Affix labels neatly.

z

Cable ties bundle power cables in the same position, with ID plates on the same side.

z

The positions of “up”, “down”, “right” or “left” are all based on the viewpoint of the one working on the label.

C.3 Engineering Labels for Optical Fibers These labels apply to the optical fibers that connect the optical interfaces on the boards in a subrack or a box.




There are two types of labels for optical fibers: 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 Optical Distribution Frame (ODF).

II. Example of the Label Figure C-11 shows the label on the trunk cable between the device and the DDF:




Figure C-11 Example of the label on the trunk cable between the device and the DDF “A01-03-01-01-R” indicates that local end of the trunk cable connects to the receiving terminal of Trunk Cable 01 in Slot 01, Frame 03 of the cabinet on Row A, Column 01 in the equipment room. “DDF-G01-01-01-AR” indicates that the opposite end of the trunk cable connects to the receiving terminal of Direction A (connected to optical network equipment) on Row 01, Column 01 of the DDF on Row G and Column 01 in the equipment room.

C.5 Engineering Labels for Power Cables C.5.1 Labels for DC Power Cables The labels apply to the DC cables that provide power for the cabinets, and the protection grounding cables, including the -48V, PGND, and BGND cables. The labels for DC power cables are on one side of the ID plates on cable ties.

I. Meaning of the Label Table C-6 shows the information carried on the labels for the DC power cables: Table C-6 Information on labels affixed to the DC power cables Content

Meaning

MN(BC)--48V1

MN (BC): BC is right under MN.

MN(BC)--48V2

On the load cabinet side, MN alone can identify the cabinet.

MN(BC)-BGND

On the power 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 -48V 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.

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 Huawei Technologies Proprietary C-14



C-6 lists the information of two -48 V power supplies on the label. The information of other DC voltages (such as 24 V and 60 V) is similar.

II. Example of the Label Be sure to affix labels in a correction direction. Make sure that the ID plates with the labels face outwards when bundling the cables with cable ties. Make sure that the text on the labels in a cabinet are in the same direction, as shown in Figure C-12. TO: A01 B08

-48V2

TO: B03

(1)

-48V2

(2)

Figure C-12 Example of the labels on the DC power cable In Figure C-12, (1) indicates the label on the load cabinet side, which carries the information about the position of the cable on the power distribution box. (2) indicates the label on the distribution box side, which carries the information about the position of the cable on the load cabinet side. On the load cabinet side, the label marked with “A01/B08--48V2” on the cable indicates that the cable is for -48V2 DC supply, which is from the 8th connector on the second row of -48V bus bar in the cabinet on Row A, and Column 1 in the equipment room. On the distribution box side, the label marked with “B03--48V2” indicates that the cable is for -48V2 DC supply, which is from the load cabinet on Row B, Column 03 in the equipment room.




Note: z

In the power distribution box (or the first power cabinet of a row in the transmission equipment room), every terminal block on the -48V connector bar has a numeric identification. For example, in the above label of “A01/B08--48V2”, “08” (or sometimes “8”) is the numeric identification of the terminal block.

z

PGND and BGND are two copper bars. On each bar, the terminal blocks are short-circuited. Therefore, which terminal is connected makes no difference. You only need give the row number and column number of the power distribution box, instead of giving the specific serial number of the terminal block on the copper bar. For example, if the label on the load cabinet side is “A01-BGND”, it means that the power cable is a BGND that connects BGND copper bar in the power distribution box on Row A, Column 01 in the equipment room. The information on the labels for PGND cables is similar.

Figure D-2 Dust-free pick (2)

D.2.2 Selection Select a cleaning means for an optical fiber connector depending on the transmission rate of the fiber, specifically: z

Dust-free cloth and anhydrous alcohol are applicable to the fiber connectors that bear low-rate (2.5 Gbit/s or low) transmission.

z

Wiping paper, wiping boxes, and dust-free picks are applicable to the fiber connectors that bear high-rate (10 Gbit/s or wavelength division system) transmission.

z

Dust-free picks are applicable to the fiber connector that integrates an optical module with a flange on the front panel of a board.

D.3 Cleaning Requirements The requirements for the cleaning of an optical fiber connector are as follows: 1)

Clean the places around the optical fiber connector before cleaning the connector.



2)

Appendix D


Insert the optical fiber connector immediately into the corresponding optical sub-board or flange after cleaning it lest the corresponding port on the sub-board or flange becomes dirty.

3)

Do not touch the end face of the optical fiber connector after cleaning it. Cover it with a protective cap if it is not in use for the moment.

4)

Clean the flange on the optical subboard and the optical port in the board only when:

z

The detected optical power performance of the subboard supporting optical power detection is greatly different from the actual measured optical power.

z

The subboard that does not support optical power detection reports alarms or the transmit optical power of the subboard is greatly different from the typical optical power even if the receive optical power is within its working range.

5)

Examine the optical port surface using a fiber microscope. Make sure that the optical port is clean.

z

When the Raman amplifier applies to the wavelength division multiplexing (WDM) system, examine the surfaces of all optical ports before the input ports using a fiber microscope.

z

Examine the surfaces of all optical ports on the link of long-distance transmission (over 120 km) of WDM equipment and 10G MADM equipment.

D.4 Precautions I. Fiber Protection The protection requirements for optical fibers are as follows: z

Never bend fibers smaller than 90°.

z

Coil up extra fibers into a round or “8”. Never wind them around each other.

z

Never apply more than 1 kg axial tension to a fiber. Never hang anything on only a fiber.

z

Never apply any impulse force to the axis of a fiber. Protect the optical fibers from crush.

z

Never place any optical fiber at 85 °C or higher.

II. Laser Safety Never look at the exit of an optical fiber directly lest the laser injures eyes.
