The base transceiver station (BTS) has RF radiation (radiation hazard). Suggestions for theinstallation and operation of BTSs are given in the following section. Operators are also requiredto comply with the related local regulations on erecting BTSs.



1-7

l The antenna should be located in an area that is inaccessible to the public where the RFradiation exceeds the stipulated value.

l If the areas where RF radiation exceeds the stipulated value are accessible to workers,ensure that workers know where these areas are. They can shut down the transmitters beforeentering these areas. Such areas may not exist; but if they exist, the areas must be within arange of less than 10 m around the antennas.

l Each forbidden zone should be indicated by a physical barrier and striking sign to warn thepublic or workers.

Laser

CAUTIONWhen handling optical fibers, do not stand close to, or look into the optical fiber outlet withunaided eyes.

Laser transceivers or transmitters are used in the optical transmission system and associated testtools. Because the laser that is transmitted through the optical fiber produces a small beam oflight, it has a very high power density and is invisible to human eyes. If a beam of light entersthe eye, the retina may be damaged.

Normally, staring into the end of an unterminated optical fiber or broken optical fiber with theunaided eyes from a distance of more than 150 mm (6 inches) will not cause eye injury. Eyesmay, however, be damaged if an optical tool such as a microscope, magnifying glass or eyeloupe is used to stare into the bare optical fiber end.

Read the following guidelines to prevent laser radiation:

l Only the trained and authorized personnel can perform the operation.

l Wear a pair of eye-protective glasses when you are handling lasers or optical fibers.

l Ensure that the optical source is switched off before disconnecting optical fiber connectors.

l Never look into the end of an exposed optical fiber or an open connector if you cannotensure that the optical source is switched off.

l To ensure that the optical source is switched off, use an optical power meter.

l Before opening the front door of an optical transmission system, ensure that you are notexposed to laser radiation.

l Never use an optical tool such as a microscope, a magnifying glass, or an eye loupe to lookinto the optical fiber connector or end.

Read the following instructions before handling optical fibers:

l Only the trained personnel can cut and splice optical fibers.

l Before cutting or splicing an optical fiber, ensure that the optical fiber is disconnected fromthe optical source. After disconnecting the optical fiber, use protecting caps to protect allthe optical connectors.

7.3 Principles of Routing and Binding the Power Cables andPGND Cables

This describes the principles for routing and binding the BSC power cables and PGND cables.When installing the BSC power cables and PGND cables, abide by the principles.

Principles of Routing Cablesl The layout of power cables and PGND cables must facilitate future expansion.

l The power cables and PGND cables must be separated from the other cables. When thepower cables and the PGND cables are laid parallel to signal cables, the spacing betweenthem must be at least 30 mm.

l The bending radius must be five times greater than the diameter.

l In underfloor cabling mode, a surplus length of power cable must be reserved outside thecable inlet of the power distribution box on the top of the cabinet. This facilitates theinstallation of the terminal. In addition, the cables must be laid flat on the top of the cabinet.

l When connecting power cables to the terminals of the power distribution box, lay the cablesstraight and smoothly.

Principles of Binding Cablesl The power cables and PGND cables must be separated from the signal cables.

l The spacing between cable ties must be 200 mm.

l If the underfloor cabling mode is used, the power cables and PGND cables should be routedalong the middle column on the right of the cabinet front.

l The selection of cable ties depends on the diameter (150 mm/300 mm) and quantity ofcables.

l The cable ties are bound in the same direction. The extra length of the cable ties are cutand the cut surfaces are smooth without sharp edges.

9 Checking and Setting the DIP Switch of theSubrack

This describes how to install the subrack of the BSC, and then check and set the DIP switch ofthe subrack. In general, subracks are installed on the rack when the BSC is delivered.

PrerequisiteThe subrack whose DIP switch needs to be set is installed.

Context

CAUTIONWear an ESD wrist strap and ensure that it is properly connected to the ESD connector on thecabinet. For details, refer to Wearing an ESD Wrist Strap.

The DIP switch is used to configure the number of the subrack. Figure 9-1 shows the cover forthe DIP switch of the subrack.

Figure 9-1 Cover for the DIP switch of the subrack

7 Reserved, undefined, generally set to 0 (ON)

8 (the most significantbit)

l For the GMPS and the main GTCS on the MSC side, the bitshould be set to 1 (OFF).

l For the GEPS and a non-main GTCS, the bit should be set to0 (ON).

Bit 8 (the most significant bit) is used to set the startup mode of the GSCU in the subrack. Thedefinitions of this bit are as follows:l If this bit is set to 0 (the status of the DIP bit is ON), the GSCU is set to Not Start

Automatically. The startup of the GSCU depends on the GOMU. In other words, when theGSCU is started, it loads data from the GOMU.

l If this bit is set to 1 (the status of the DIP bit is OFF), the GSCU is set to Start Automatically.When the GSCU is started, it checks whether the Flash file is valid. If the Flash file is valid,the GSCU loads data from the Flash. If the Flash file is invalid, the GSCU loads data fromthe GOMU.

NOTE

l When a new BSC is deployed, or a BSC is upgraded from V900R001 or V900R001C04 to V900R008,bit 8 of the GMPS and the main GTCS on the MSC side must be set to 1 (OFF). For the GEPS andother GTCSs, bit 8 must be set to 0 (ON).

l If the BSC6000 V900R008 is upgraded between B versions or between C versions, you do not needto reset the DIP bits.

As the DIP switches use odd parity check, the number of 1s in the eight DIP bits must be an oddnumber. The setting should adhere to the following principles:

1. Set DIP bits 1 through 5 and DIP bit 8.2. Set DIP bit 7 to 0.3. Count the number of 1s that have been set.

l If the number of 1s is even, set DIP bit 6 to 1.

l If the number of 1s is odd, set DIP bit 6 to 0.

Assume that the subracks are numbered from 0 to 3. For the setting of the DIP switches in thiscase, refer to Table 9-2. Subrack 0 should be the GMPS or the main GTCS on the MSC side.Subracks 1 to 3 may be the GEPS or the non-main GTCS.

11.2 Installation Principles of the BSC Signal CablesThis describes the installation principles of the BSC signal cables. The cables should meet therequirement for minimum bending radius, the principles of laying cables, the principles ofrouting cables, and the principles of binding cables.

Overall PrinciplesWhen installing the BSC signal cables, pay attention to the following points:

l The optical cable should not be stretched roughly or stepped on. Heavy objects should notbe placed on the cable. In addition, the cable should be kept away from sharp objects toavoid damage.

l An optical connector must be covered with dustproof caps when it is not in use.

l If the connectors of the signal cables are made before delivery, you should pack theconnectors with soft and durable materials during cabling.

l Protect the jackets of the signal cables from being damaged during the routing.



11-3

l When coiling the extra length of optical cables on the fiber management tray, apply forceevenly to minimize damage to the optical cables.

l The actual installation positions must meet the requirements of site survey and dataconfiguration.

l When installing the signal cables, you should route the extra part of the interconnectioncables on both sides of the cabinet according to the requirement for the bending radius ofthe cables.

l The related operation guide is intended for only the installation method. The actualinstallation position of cables should cater to the demand of site survey and should beconsistent with the data configuration scheme.

Minimum Bending RadiusThe bending radius of the BSC signal cable satisfies the requirements of all kinds of cables.Table 11-2 lists the bending radius of the signal cables.

Table 11-2 Requirements for the bending radius

Cable Bending Radius

Ethernet cable Not less than 25 mm

Trunk cable Not less than 40 mm

75-ohm coaxial clock signal cable Not less than 45 mm

Inter-GSCU cable Not less than 25 mm

Signal cableof the alarm box

Not less than 25 mm

PDB monitoring signal cable Not less than 25 mm

Optical cable Not less than 40 mm

Principles of Laying CablesTo facilitate maintenance and expansion, adhere to the principles when routing cables.

The layout sequence in overhead and underfloor cabling modes must be the same. The principlesare as follows:

l The cables meant for the front of the cabinet must be laid only in the front side of the cabinet.Do not lead in the cables around the rear side of the cabinet. Follow the same principle forthe cables meant for the rear of the cabinet.

l When routing cables at the front side of the cabinet, ensure that the signal cables and clocksignal cables for the GSCU are separated from the inter-GTNU cables. The inter-GTNUcables are routed from right to left. The signal cables and clock signal cables for the GSCUare routed from left to right. Route the signal cables that are led out of the GSCU before




Issue 02 (2008-06-30)

routing the signal cables that are led out of the GGCU. The routing of other signal cableshas no sequence.

l While routing the cables at the rear of the cabinet, route the trunk cables before routing theoptical cables.

Principles of Routing CablesAdhere to the following principles when routing signal cables:

l Protect the jackets of the signal cables from being damaged during the routing.

l Hold the connector when plugging out the signal cable to protect the signal cable frombeing damaged.

l When installing the signal cables, you should route the extra part of the interconnectioncables on both sides of the cabinet according to the requirement for the bending radius ofthe cables.

l For combined cabinets, the extra signal cable in front of the cabinet should be routed alongthe cable ladder or at one side of the cabinet. It should not be placed in the gap between thecombined cabinets.

l The signal cables and power cables must be laid separately. If they have to be installedcrosswise, cross them at an angle of 90 degrees.

l The bending radius of the BSC signal cable satisfies the requirements of all kinds of cables.Table 11-2 lists the bending radius of the signal cables.

l Extra length of the signal cable should be reserved near the connector.

l The signal cables must be neatly laid in the rack, according to the engineering design.

l If the height difference between the cable rack and the top of the cabinet exceeds 800 mm,a downward cable ladder must be used. The signal cables and the lower part of thedownward cable ladder must be bound together.

l The routing should be in accordance with the engineering design.

l The cabling is clear, proper, and smooth at the bends. The cables are laid in parallel.

l The signal cables layout facilitates maintenance and future expansion.

Principles of Binding CablesAdhere to the following principles when routing signal cables:

l The signal cables and power cables must be bound separately. The spacing between cableties must be at least 150 mm.

l The twines for binding the cables must be coated with wax.

l The signal cables must be bound at the entrance and exit of the cable trough and at theturning points, as shown in Figure 11-1.
