B. Upgrade from Old PMU

Use this procedure only if your Site Controller cabinet has EDACS Interface panels and an old PMU.

This procedure consists of upgrading the Site Controller by replacing the old PMU, replacing the old Power Sensor interface module, and replacing the cables between them.

Parts Required

Before you start this procedure, be sure you have all the parts on hand. The parts for this procedure are shown in Table 3.

Procedure

The following steps involve equipment in the Site Controller cabinet only:

1.Turn off the main 12V power supply for the cabinet.

2.Mark “+” on the wire going to the screw terminal marked “+” on the back of the old PMU. Then disconnect this wire at the PMU end.

3.Mark “–” on the wire going to the screw terminal marked “–” on the back of the old PMU. Then disconnect this wire at the PMU end.

4.Mark “RS-232” on the cable going to the DB-25 connector marked “RS-232” on the back of the old PMU. Then disconnect this cable at the PMU end.

5.Disconnect any cables going to the connectors marked “Antennas 1-4”, “Transmitters 1-9”, “Transmitters 10- 18”, and “Transmitters 19-20” on the back of the old PMU. (There is no need to label these cables since they will not be used with the new PMU.)

6.Replace the old PMU with the new PMU. There will be a half rack unit space (7/8 inch) both above and below the new PMU.

7.Connect the existing wire labeled “+” in step 2 to the terminal labeled “+” on the back of the new PMU.

8.Connect the existing wire labeled “–” in step 3 to the terminal labeled “–” on the back of the new PMU.

9.Connect the existing cable labeled “RS232” in step 4 to the right-hand VDT interface on the back of the new PMU (see Figure 7).

10.Find the Power Sensor interface module mounted in the left end of the upper EDACS Interface Panel in the upper rear of the cabinet. If a cable is connected to the

LBI-39128 specifications

Ericsson LBI-39128 is a comprehensive communication solution designed to meet the ever-evolving demands of modern telecommunications. It is renowned for its ability to enhance network performance while providing a robust framework for various communication technologies. This product primarily targets service providers, enabling them to maximize their operational efficiency and improve service delivery.

One of the key features of the LBI-39128 is its versatility in supporting multiple generation technologies, including 2G, 3G, LTE, and even 5G. This ensures that service providers can seamlessly integrate their existing infrastructure and gradually evolve towards more advanced network capabilities without the need for a complete overhaul. The product caters to a wide array of deployment scenarios, from urban environments with high user density to rural areas requiring expansive coverage.

In terms of network performance, the LBI-39128 excels with its advanced radio technologies. It employs Massive MIMO (Multiple Input Multiple Output) and beamforming techniques, which significantly enhance spectral efficiency and improve user experience. With multiple antennas transmitting and receiving signals simultaneously, users benefit from increased throughput and reduced latency, essential for applications such as video streaming and real-time communications.

Another critical characteristic of the Ericsson LBI-39128 is its focus on energy efficiency. The product integrates intelligent power management systems that optimize energy consumption, thereby reducing operational costs for service providers. This aligns with the growing emphasis on sustainable practices within the telecommunications industry.

Moreover, the LBI-39128 features advanced management and automation capabilities. Its network function virtualization (NFV) support enables operators to deploy virtualized network functions efficiently, allowing for dynamic scaling and resource allocation based on real-time demand. This agility is crucial for handling varying loads and enhancing the overall resilience of the network.

Security is also a primary consideration in the design of the LBI-39128. It incorporates robust encryption methods and secure access protocols to protect sensitive data and ensure the integrity of communication channels. This is particularly important in an age where cyber threats are becoming increasingly prevalent.

In summary, the Ericsson LBI-39128 is a state-of-the-art telecommunications solution that stands out due to its support for multiple technologies, advanced radio capabilities, energy efficiency, automated management, and robust security features. Its design reflects the needs of contemporary service providers, allowing them to build and sustain high-performance networks that meet the demands of future communications.
