1. Remote Radio Head(RRH) – ODU : 3 no’s

2. Base Controller Unit(BSC) – IDU : 1 no

3. GPS Antenna : 1no

4. 120 degree Sector Antenna : 3 no’s

5. 2mtr Pigtail Cable : 6 no’s

8. BSC(IDU) Power Cable with Connector : 2 no’s

Component Inspection: • Carefully unpack the PointMAX package and inspect the unit for physical damage. • Verify that all the components are present against the shipping information or purchase order. Immediately contact PointRed Telecom (P) ltd., if any portion of the system is missing or damaged. 2.2. Installation Physical installation of the PointMAX system installation includes two steps as follows:

• RRH – ODU installation. • BSC – IDU installation.

2.2.1 Remote Radio Head (ODU) installation:

• RRH has to be installed on the tower/mast using appropriate clamps. • 3 RRH installed on the tower represent each per Sector. • Connect Pigtail(2 per RRH) from each RRH to Antenna • Install and Connect Fibre cable from each RRH to IDU in appropriate module(PM 18) • Install the Power cable using power connector provided to each RRH. • Install GPS Antenna with cables using appropriate clamps provided & connect to BSC

unit (PM 18 module). • Install Grounding cable to each RRH using proper lugs and connect to Earth Point.

2.2.3 DC Power Supply The power connector is of AMP Tyco CPC series 5 type. The cable connector is shown in below Figure.

The connector is wired as follows:

Pin 1

Negative Supply

Pin 2

Positive Return

Pin 3

On the mating (RRH) connector this pin is

connected to chassis Earth

Cable crimp pins are available in two sizes. One to fir cable gauge AWG 8-10 and one to fit AWG 12-14. Either can be fitted although the cable gauge determines the maximum length of power cable that can be supported. 2.2.4 Recommended Maximum Power Supply Cable Length The power cable should be AWG12 minimum gauge, specified to NEC/ CEC.ANSI/NFPA 70. The cable length should be sufficient to make sure that the cable voltage drop under highest current load does not increase the input voltage at the RRH above -36V the maximum allowable cable length can be calculated using the following equation:


Maximum cable length (m) = 1000 X (VPSU – 36) / (IMAX X 2 X CableRES) Where the maximum current IMAX is typically 5.5A, the source voltage VPSU is -48V and the cable RES is the cable resistance expressed as ohm/Km. This value will depend upon the manufacturer and gauge of cable. For AWG12 cable with a resistance of 5.2 ohm/Km this would give a maximum cable length of 209m. However, if back up battery power is used with a voltage of 40V the maximum cable length is reduced to 70m.

2.2.5 Earth Requirements The RRH must be connected to the local earth bonding point and has a connection for this purpose. This is two M6X6mm deep holes on a 15.5mm pitch. The earth strap should be AWG10 minimum diameter. The inputs to the RRH power supply are isolated from chassis ground. However the positive terminal can be connected to local (chassis) earth external to the RRH as required (access via pin 3 of chassis socket). 2.2.6 Fuse The RRH is fitted with a 5A anti‐surge fuse fitted to the supply line (‐48V nominal). 2.2.7 Optical Connector The optical input carries the digital IQ data and unit control data. The standard optical wavelength is 850nm. The fibre fitted is a multi‐mode fibre. The connectors are ODC2 Flange mount. In the case that 2 optical connectors are fitted the left hand optical 1 is the primary connector. 2.2.8 Health and Safety The unit weighs approximately 12Kg; so it is recommended that care should be exercised when lifting the product. Appropriate safety gear should be used at all times. If using a hoist to lift the unit up a mast, attach the rope to the carrying handle at the top of the unit.


2.2.9 RRH Mounting Fit the mounting brackets to the unit as described in below diagram of the mounting Instructions,

Fig 1 Fig 2 Fig 3

• Attach studs supplied to the outer pair of the holes on a mounting bracket as shown Figure 3.

• Tighten the pair of nuts against the brackets to a torque of 15Nm.

• Thread a nut and washer onto the free end of each stud as shown in Figure 4.

• Position the upper pair of pole mounting brackets in the required position for the unit to

be mounted on the pole. Secure the brackets in position using a washer and nut to a torque of 15Nm, as shown in fig 4. Once tight the nut should then be locked by tightening the opposing against the other side of the pole mounting bracket, ensuring that it does not move. Note: For the upper bracket the hooks should point upwards.

• Repeat steps i to iv for the lower bracket, positioning the pair of brackets approximately

350mm lower on the pole, with the hooks facing downwards and the brackets only tightened loosely against the pole.

• Hook the slot in the unit mounting brackets onto the hook on the upper pole mounting

bracket, see Figure 5.


• Slide the lower pair of mounting brackets down the pole until the hooks locate into the slots on the lower unit mounting bracket, as shown in Figure 5.

• Secure the lower pair of pole mounting brackets firmly in position against the pole and

lock the nuts against each other.

• Secure the unit to the pole mounting brackets using the M8 screws, washers, spring washers and nuts provided, using a torque of 15Nm, as shown in Figure 5.

Ensure all nuts are tightened to a torque of 15Nm

2.2.10 Base Station Controller Unit (IDU) installation

• BSC unit is Horizontal-mounted six (6) slots, 2U 19”inch rack-mounted enclosure. • BSC unit has to be installed on the Rack using appropriate check nets. • Check in the BSC unit, 8 modules are inserted properly as shown in the diagram. • Install the power Cable with power Connector provided to BSC unit. (PM 14

Module). • BSC unit has two power modules (PM 14) which supports power redundancy, so

install power cables for both modules for redundancy. • Install CAT6 cable from BSC unit (PM 17 module) to backhaul provided. Eg: switch.

The backhaul cable has to be connected to “Ethernet port ETH 1” in PM 17 module of BSC unit.

• BSC unit has two Controller Cards (PM 17) to support 1+1 functionality, so install backhaul cable for both modules to support redundancy.


• Connect the fibre cable which is laid from RRH to BSC unit (PM 18 Module) using STP fibre module.

• Connect the GPS cable which is laid from GPS to BSC unit (PM 18 Module) in “GPS port”.

• BSC unit has two hot swappable & manageable cooling units (Fan). • Install Grounding cable to BSC unit using proper lugs and connect to Earth Point. • Power on the BTS, check for “READY LED”. RDY LED’s in respective modules

has to turn “Green” (LED in Top Left most end in the each module) in order to know all modules are activated. Fibre Port & GPS Port LED’s should also turn “GREEN”, in order to know that respective device is active. If LED indication is “Orange”, it shows device is inactive. Note: All modules have to be handled carefully. Refer to Module Handling document.

Note: All modules have to be inserted in respective slots, as shown in the above diagram. The module has to be inserted properly in the respective slot using Hot swap lever (Black Nob) & Nob has to pressed fully for the module to become Active. While removing the module, initially the Nob has to be pull back wait for 10 sec till the LED’s turns blue then remove from the slot.
