Installation Scenarios
About This Chapter A DBS3900 mainly consists of the BBU and RRUs. With RRUs remotely installed, the DBS3900 can be deployed indoors and outdoors. If a DBS3900 is installed outdoors with AC or DC power supply, the BBU can be installed in an outdoor APM30H, TMC11H, TP48600A-H17B1 (shortened to TP48600A in this document), or OMB. If a DBS3900 is installed indoors with AC or DC power supply, the BBU can be installed in an IMB03, a 19-inch rack, or directly installed on the wall. 3.1 Outdoor Installation Scenarios with AC Power Supply This section describes the outdoor installation scenarios where a DBS3900 is supplied with AC power. 3.2 Outdoor Installation Scenarios with DC Power Supply This section describes the scenarios where the DBS3900 is installed outdoors and is supplied with DC power. 3.3 Indoor Installation Scenarios with AC Power Supply This section describes the scenarios where the DBS3900 is installed indoors and is supplied with AC power. 3.4 Indoor Installation Scenarios with DC Power Supply This section describes the indoor installation scenarios where a DBS3900 is supplied with DC power.

Configurations of Cabinets Used by a DBS3900 Overall principles for configuring a DBS3900 l
When being configured with an APM30H (Ver.D), a DBS3900 can support a maximum of 15 RRUs. When being configured with an OMB, a DBS3900 can support only one RRU. When being configured with an OMB (Ver.C), a DBS3900 can support a maximum of 6 RRUs. When being configured with other cabinets, a DBS3900 can support a maximum of 12 RRUs.
l
During initial deployment, the basic cabinet is positioned on the right and the auxiliary cabinets such as the battery cabinet and transmission cabinet, if required, are positioned on the left. During capacity expansion, unless otherwise stated, the original cabinets remain in the original positions and new cabinets are added to the right side of original cabinets.
The principles for configuring the DBS3900 of which the BBU is installed in an APM30H cabinet are as follows: l
An APM30H can be installed side by side with only one TMC11H, or it can be stacked on a maximum of two IBBS200Ds/IBBS200Ts/IBBS300Ds/IBBS300Ts. (An IBBS200D/ IBBS200T/IBBS300D/IBBS300T can be stacked on another cabinet of the same type.)
l
An APM30H or TMC11H can be installed on the ground or stacked on an IBBS200D, IBBS200T, IBBS300D, or IBBS300T.
l
An APM30H (Ver.D) can be installed side by side with only one IBBS700D or IBBS700T.
l
If both the battery cabinet and transmission cabinet are required, the battery cabinet is positioned on the left side of the basic cabinet, and the transmission cabinet is stacked on the battery cabinet or positioned on the left side of the battery cabinet.
The principles for configuring the DBS3900 of which the BBU is installed in a TP48600A cabinet are as follows: l
A TP48600A can be installed together with a TMC11H (Ver.C) side by side.
l
A TP48600A can be installed together with an IBB300D, IBBS300T, IBBS700D, or IBBS700T side by side.
BBU Installed in an APM30H (Ver.D) or TMC11H (Ver.D) NOTE
APM30H (Ver.D) is shortened to APM30H, and TMC11H (Ver.D) is shortened to TMC11H.
Single- or dual-mode base station An APM30H cabinet can supply power to a maximum of 15 RRUs. When a base station is configured with 7 to 12 RRUs, another DCDU-12B must be added to the APM30H. When a base station is configured with 13 to 15 RRUs, an ODM and an OFD must be configured. Issue 03 (2014-08-30)

l
When routing cables, avoid sharp objects, for example sharp edges on the wall. If necessary, use tubes to protect the cables.
l
When routing cables, keep the cables away from heat sources and use heat insulation materials to insulate the cables from the heat sources.
l
Reserve a proper distance (0.1 m or 3.937 in. is recommended) between equipment and cables especially at the cable curves to protect the cables and equipment.
Indoor cabling requirements l
Route each cable into the room through the feeder window.
l
Reserve drip loops for all cables outside the feeder window before routing them into the room. Ensure that the radiuses of the drip loops are greater than or equal to the minimum bending radiuses of the cables.
l
When routing a cable into the room, ensure that a person is assisting you in the room.
l
Apply waterproof treatment to the feeder window.
Outdoor Cabling Requirements l
Protect outdoor cables against potential damage. For example, put the cables through tubes.
l
The cables to be protected include AC power cables, transmission cables, and cables laid out underground.
l
When routing cables through tubes on the ground below the cabinet, put a 30 mm to 50 mm (1.18 in. to 1.97 in.) length of the tubes into the base of the cabinet but do not put the tubes into the cabinet. Use waterproof tape or waterproof silicon gel to block both ends of the tubes and use sheet metal tabs to secure the tubes to the cable holes in the base.
l
When routing cables through tubes along a metal cable trough below the cabinet, do not put the tubes into the base of the cabinet but cover the cable trough and connect the tubes to the cable holes in the base.
l
Use clips to secure cables outdoors. For the method of installing a clip, see the installation guide delivered with the clip.
l
Arrange cables neatly along the routing direction and use clips to secure the cables.
l
Determine the positions where the clips are installed according to the actual situation. For example, 7/8" feeders are secured with clips at an interval of 1.5 m to 2 m (4.92 ft to 6.56 ft), CPRI fiber optic cables and power cables are secured with clips at an interval of 1 m to 1.5 m (3.28 ft to 4.92 ft). Ensure that the clips are evenly spaced and in the same direction.
l
When fastening cables with a clip, ensure that the cables are aligned neatly and are routed through the holes in the clip. Do not stretch the cables too tightly. NOTE
There are two types of clips: 3-hole clip and 6-hole clip, which are described as follows: l
A 3-hole clip is shown by illustration a in the following figure. It is often used to fasten feeders.

Check as follows: 1. Remove the board, and check whether any pin of the slot on the backplane is bent, broken, or missing. Replace the subrack if necessary. 2. Insert the board into the subrack, and check the status of indicators on the board. 3. If the indicators indicate an exception, remove the board, insert it into a vacant slot holding the boards of the same type, and check the status of the indicators. l If the board works properly, the original slot is faulty. In this case, replace the subrack. l If the fault persists, the board is faulty. In this case, replace the board.
Failure in the power supply to other components in the cabinet
Check as follows: 1. Check whether the indicator on the fuse terminal block that connects power supply to the component is on. Skip this step and go to step 2 if this component does not use any fuse terminal block. l If the indicator on the fuse terminal block is on, the fuse is faulty. In this case, replace the fuse according to the instructions in Replacing a Fuse. l If the indicator on the fuse terminal block is off, go to step 2. 2. Use a multimeter to measure the input power to the component. l If the input power is normal, replace the component. l If the input power is abnormal, check whether the power cable for the component is connected securely. If the power cable is not securely connected, turn off the circuit breaker for the component (if there is no circuit breaker for the component, remove the connector from the power unit) and reconnect the power cable. If the power cable is securely connected, the protector (such as circuit breaker or fuse) on the component may be damaged. In this case, replace the damaged protector.

Handling Measure
Failure in the power supply to a board in the BBU
Check as follows: 1. Remove the board, and check whether any pin of the slot on the backplane is bent, broken, or missing. Replace the subrack if necessary. 2. Insert the board into the subrack, and check the status of indicators on the board. 3. If the indicators indicate an exception, remove the board, insert it into a vacant slot holding the boards of the same type, and check the status of the indicators. l If the board works properly, the original slot is faulty. In this case, replace the subrack. l If the fault persists, the board is faulty. In this case, replace the board.
Failure in the power supply to other components in the cabinet
Check as follows: 1. Check whether the indicator on the fuse terminal block that connects power supply to the component is on. Skip this step and go to step 2 if this component does not use any fuse terminal block. l If the indicator on the fuse terminal block is on, the fuse is faulty. In this case, replace the fuse according to the instructions in Replacing a Fuse. l If the indicator on the fuse terminal block is off, go to step 2. 2. Use a multimeter to measure the input power to the component. l If the input power is normal, replace the component. l If the input power is abnormal, check whether the power cable for the component is connected securely. If the power cable is not securely connected, turn off the circuit breaker for the component (if there is no circuit breaker for the component, remove the connector from the power unit) and reconnect the power cable. If the power cable is securely connected, the protector (such as circuit breaker or fuse) on the component may be damaged. In this case, replace the damaged protector. If the protector cannot be replaced, replace the upper-level power distribution component.

Failure Type
Handling Measure
Failure in the power supply to a board in the BBU
Check as follows: 1. Remove the board, and check whether any pin of the slot on the backplane is bent, broken, or missing. Replace the subrack if necessary. 2. Insert the board into the subrack, and check the status of indicators on the board. 3. If the indicators indicate an exception, remove the board, insert it into a vacant slot holding the boards of the same type, and check the status of the indicators. l If the board works properly, the original slot is faulty. In this case, replace the subrack. l If the fault persists, the board is faulty. In this case, replace the board.
Failure in the power supply to other components in the cabinet
Check as follows: 1. Check whether the indicator on the fuse terminal block that connects power supply to the component is on. Skip this step and go to step 2 if this component does not use any fuse terminal block. l If the indicator on the fuse terminal block is on, the fuse is faulty. In this case, replace the fuse according to the instructions in Replacing a Fuse. l If the indicator on the fuse terminal block is off, go to step 2. 2. Use a multimeter to measure the input power to the component. l If the input power is normal, replace the component. l If the input power is abnormal, check whether the power cable for the component is connected securely. If the power cable is not securely connected, turn off the circuit breaker for the component (if there is no circuit breaker for the component, remove the connector from the power unit) and reconnect the power cable. If the power cable is securely connected, the protector (such as circuit breaker or fuse) on the component may be damaged. In this case, replace the damaged protector. If the protector cannot be replaced, replace the upper-level power distribution component.

Insert the board into the subrack, and check the status of indicators on the board. 3. If the indicators indicate an exception, remove the board, insert it into a vacant slot holding the boards of the same type, and check the status of the indicators. l If the board works properly, the original slot is faulty. In this case, replace the subrack. l If the fault persists, the board is faulty. In this case, replace the board.
Failure in the power supply to other components in the cabinet
Check as follows: 1. Check whether the indicator on the fuse terminal block that connects power supply to the component is on. Skip this step and go to step 2 if this component does not use any fuse terminal block. l If the indicator on the fuse terminal block is on, the fuse is faulty. In this case, replace the fuse according to the instructions in Replacing a Fuse. l If the indicator on the fuse terminal block is off, go to step 2. 2. Use a multimeter to measure the input power to the component. l If the input power is normal, replace the component. l If the input power is abnormal, check whether the power cable for the component is connected securely. If the power cable is not securely connected, turn off the circuit breaker for the component (if there is no circuit breaker for the component, remove the connector from the power unit) and reconnect the power cable.

l
When routing cables, keep the cables away from heat sources and use heat insulation materials to insulate the cables from the heat sources.
l
Reserve a proper distance (0.1 m or 3.937 in. is recommended) between equipment and cables especially at the cable curves to protect the cables and equipment.
Indoor cabling requirements l
Route each cable into the room through the feeder window.
l
Reserve drip loops for all cables outside the feeder window before routing them into the room. Ensure that the radiuses of the drip loops are greater than or equal to the minimum bending radiuses of the cables.
l
When routing a cable into the room, ensure that a person is assisting you in the room.
l
Apply waterproof treatment to the feeder window.
Outdoor Cabling Requirements l
Protect outdoor cables against potential damage. For example, put the cables through tubes.

Failure Type
Handling Measure
Failure in the power supply to a board in the BBU
Check as follows: 1. Remove the board, and check whether any pin of the slot on the backplane is bent, broken, or missing. Replace the subrack if necessary. 2. Insert the board into the subrack, and check the status of indicators on the board. 3. If the indicators indicate an exception, remove the board, insert it into a vacant slot holding the boards of the same type, and check the status of the indicators. l If the board works properly, the original slot is faulty. In this case, replace the subrack. l If the fault persists, the board is faulty. In this case, replace the board.
Failure in the power supply to other components in the cabinet
Check as follows: 1. Check whether the indicator on the fuse terminal block that connects power supply to the component is on. Skip this step and go to step 2 if this component does not use any fuse terminal block. l If the indicator on the fuse terminal block is on, the fuse is faulty. In this case, replace the fuse according to the instructions in Replacing a Fuse. l If the indicator on the fuse terminal block is off, go to step 2. 2. Use a multimeter to measure the input power to the component. l If the input power is normal, replace the component. l If the input power is abnormal, check whether the power cable for the component is connected securely. If the power cable is not securely connected, turn off the circuit breaker for the component (if there is no circuit breaker for the component, remove the connector from the power unit) and reconnect the power cable. If the power cable is securely connected, the protector (such as circuit breaker or fuse) on the component may be damaged. In this case, replace the damaged protector. If the protector cannot be replaced, replace the upper-level power distribution component.
