In addition to industry standard tools, you will need the materials described in Table 2-1 during the installation.

Installation Tools
The following tools are needed during the installation.

Location & Environment

In addition to network planning, when determining where to place the eNB you need to consider factors such as climate, hydrology, geology, the possibility of earthquakes, reliable electric power, and transportation access. Avoid locating the eNB in areas where there may be extreme temperatures, harmful gases, unstable voltages, volatile vibrations, loud noises, flames, explosives, or electromagnetic interference (e.g., large radar stations, transformer substations). Avoid areas prone to impounded water, soaking, leakage, or condensation.
Table 2-2 provides typical environmental specifications for this eNB.

Personnel Requirements
The installation personnel must master the basic safe operation knowledge, through the training, and having the corresponding qualifications.

Lightening & Grounding Protection 

You must protect the eNB against lightning. Following are guidelines concerning grounding.

• The yellow-green ground wire must be at least 10mm2 in diameter.
• In principle, always place the grounding as near as possible to the equipment.
• Connect to a reliable outdoor grounding point (earth) using one ground screw.
• The connection of the grounding points and ground bar need to be tight and reliable. Rustproofing the terminals, e.g., with anti-oxidant coating or grease, is required.

Installation

Unpacking
Before opening the box, make sure the package is in good condition, undamaged and not wet. During the unpacking, avoid potential damaging impacts from hits or excessive force. Once unpacked, check whether the quantity is consistent with the packing list.

Installation Procedure
Figure 3-1 provides an overview of the installation process.

Install on Pole
Check to ensure the diameter of the pole is in the range of 1.6inch to 2.8inch (40mm to 70mm). The position of the eNB on the pole should be at least 47 inch (120 cm) in height. Follow the steps below to install the eNB on a pole. The brackets include two parts. One part is installed on the back of the eNB, the other is for pole mounting or wall mounting.
Following will introduce how to fix the eNB on a pole.

1. Assemble the back bracket on the back of the eNB with 4 screws.

2. Assemble the pole mount part and fix it on the pole. Note that the height must satisfy the requirement described above.
   Screw hole a is used to assemble and fix the two components of the bracket, and the screw hole b is used to adjust the angle of the eNB, which helps the eNB to receive signals better.

3. Align screws holes on the back bracket with corresponding screw holes on the pole mount bracket. a corresponds to a, and b corresponds to b. First, screw at position a to mount the eNB on the pole mounting bracket. Note that do not fasten the screws. And then adjust the angle of the eNB and fasten screws at position b. At last, fasten screws at position a.

4. Proceed to “3.5 Connect Cable”.

Install on Wall
Ensure that the wall can bear at least 4 times the weight of the eNB. Follow the steps below to install the eNB on the wall.

1. Against the wall mounting bracket on the wall, with the arrow pointing up. Mark the drilling locations with a pencil or marker.
2. Drill two .4in/10mm diameter by 2.8in/70mm deep holes in the wall at the marked locations.
3. Insert expansion bolts into the two drilled holes.
4. Hang the wall mounting bracket on expansion bolts, and fasten with flat washers, spring washers and nuts in sequence.
5. Refer to the step 3 of in “3.3 Install on Pole”. Align screw holes on the back bracket with corresponding screw holes on the wall mounting bracket and fasten screws in sequence.
6. Proceed to “3.5 Connect Cable”.

Connect Cable

Cable Laying Requirements

General requirements:

• Bending radius of power cable and grounding cable: > tripled of the diameter of the cable.
• Bind the cables according the type of the cable, intertwining and crossing are forbidden.
• An identification label should be attached after the cable is laid.

Grounding laying requirements:

• The grounding cable must connect to the grounding point.
• The grounding cable must be separate with the signal cables, of enough distance to avoid signal interference.

Connect Ethernet Cable

The diameter of the Ethernet cable must is not less than 7mm. Recommend to use CAT6e shield Ethernet cable.

ATTENTION: If the diameter of the Ethernet cable is less than 7mm, the connector cannot be locked. The eNB will be flooded and damaged.

1. Unscrew the ETH connector in sequence.

2. Pass through the Ethernet cable the unscrewed connector based on original sequence.

3. Insert the RJ-45 connector to the ETH/POE port at the right bottom of the eNB.

4. Tighten the connector of the ETH/POE port in sequence.

5. Connect the other end of the Ethernet cable to the POE port of the PoE adaptor.

6. Connect the LAN port of the PoE adaptor to a LAN switch or a router for maintenance and backhaul.
   NOTE: The PoE adaptor must have lightning protection measures and be placed in a waterproof position.

7. Connect the PoE adaptor to an AC power.

Connect Ground Cable

eNB Grounding
Prepare the grounding cable according to the actual measurements and requirements of the specific installation site. The eNB has two grounding screws located on the bottom of the unit, as shown in Figure 3-2. Follow the steps below the figure to connect the ground cable.

1. Unscrew one grounding screw, connect one end of the ground cable to the grounding screw, and fasten it again.
2. Once the eNB is installed at the outdoor location, the other end of the ground cable needs to connect to a good grounding point.

Pole Grounding
The purpose of the pole grounding is to protect the equipment in the station from the damage of lightning overvoltage as far as possible. However, the interfaces between the eNB and the outside world mainly include power system, grounding system, antenna feeder and lightning receiving device, and signal line. Therefore, the damage caused by lightning mainly comes from the voltage difference between the equipment in the eNB and one or more of the four interfaces. The pole grounding is shown in Figure 3-3.

1. The installation position of the grounding bar shall meet the design requirements. The holding pole and tower body must be connected to the lightning protection network or grounded with a separate lead.
2. The diameter of the grounding wire meets the design requirements. The copper nose must be used for grounding, and the grounding resistance is required to be less than 10 ohms. If the resistance of the public network communication equipment placed in other systems is less than 10 ohms, the grounding network of the system should be overlapped.
3. The grounding wire must be the whole wire material. When laying, it should be bound separately with other cables. All grounding wires should be fixed with wire code or binding tape with a fixed spacing of 0.3m. The appearance should be straight and beautiful.
4. The copper bar must be used for the grounding bar, and the specification of the grounding bar shall meet the design requirements. If there are no specific requirements in the design, 300 × 40 × 4mm and fixed with expansion bolts.
5. The grounding wire must be made of the whole cable material, the intermediate joint is strictly prohibited, and the excess length should be cut. The skin shall be complete, and the insulation resistance of the core wire to the ground (or metal isolation layer) shall meet the technical requirements of the cable.
6. The grounding wire shall be connected to the integrated grounding bar of the building. If it is impossible to connect to the integrated grounding bar of the building, the appropriate grounding point can be selected according to the integrated grounding situation of the indoor building. The selection of grounding point must be higher than the grounding grid, and the feeder grounding shall be towards the downward direction of the feeder, never upward.
7. The grounding electrode of the self-built grounding grid for the outdoor antenna of the tunnel must meet the design requirements. The buried depth of the grounding electrode and the welding quality of the flat iron meet the specification requirements. In principle, the buried depth of the grounding electrode shall not be less than 0.7m. The non-self-built grounding network shall be connected to the grounding network of the owner.
8. The eNB grounding, power adapter grounding, distribution box grounding and feeder grounding must be connected to the grounding bar independently, and the grounding bar must have a path from the lead to the earth.

Power on to Check LED Status

Power on the eNB, and wait a few minutes while the eNB boots up. Per the previous Figure 1-1 and Table 1-2 in “1.3 Appearance”, check that the LED indicators are lighting as expected.
