R8202 Installation Guide

1. Never open the hermetic seal before and after the installation.

   

2. The RRU body is applied with antirust coating. Make sure that the coating is not damaged during transportation and installation.

3. Never install the RRU with the interface side pointing upwards.

   

4. Never install the RRU horizontally.

   

5. Do not place flammable articles on the QCell equipments.

6. The Pico RRU cannot be directly or indirectly grounded. Otherwise, the Pico RRU may fail to be powered on or have insufficient power supply. All the bare metal connectors between the external antenna interface of the Pico RRU and the antenna must be insulated.

   

1. In the pole mount device installation, the pole diameter ranges from φ60 mm to φ120 mm.

2. Do not install the device close to a fire detector. A space of at least 500 mm is required.

3. It is recommended that the Ethernet cable connecting the Pico RRU to the pBridge use the CAT-5E Unshielded Twisted Pair (UTP) cable, which satisfies the CMR protection rating requirement. The Ethernet cable length must be less than 100 m.

4. If the cable length exceeds 100 m, a network cable repeater (PEX) is required. The PEX can be mounted to the wall or bundled. The OUT end (bevel end) of the PEX is connected to the ZXSDR R8119, and the IN end is connected to the PB.

5. The Ethernet cable bends must be round, with a bending radius larger than or equal to 8 cm.

6. Repeater (PEX) installation requirements:

   • The repeater installation environment temperature is not higher than 45℃.

   • To ensure good heat dissipation, it is prohibited to cover the surfaces of the repeater except the installation contact surface by objects.

   • At least four binding cables must be used to bind the repeater.

   • The Ethernet cables must be bound tightly 10–20 cm away from the two ends of the repeater.

   • Each link can use at most one repeater.

   • The repeater must be installed horizontally. It is prohibited to install the repeater vertically.
