RPM 777 298/05000 Ericsson MU Power Cable

Product Overview

This cable is a DC power cable designed for Ericsson's Radio Base Station (RBS) equipment, specifically for powering Main Units (MUs) or Baseband Units within cabinets like the RBS 6000 series.

Key Functions & Specifications

1. Primary Function: To deliver -48V DC power from a Power Distribution Unit (PDU) or a DC Power System within a telecom cabinet to an Ericsson Main Unit (MU) or Baseband Unit.

2. Compatibility: This cable is designed for use with various Ericsson RBS models, including:

   • RBS 6000 series (e.g., 6201, 6301, 6601)

   • RBS 3000 series

3. Technical Specifications:

   • Voltage: Rated for standard telecom -48V DC.

   • Connectors: Features proprietary Ericsson connectors on one end that securely plug into the MU/Baseband unit, and typically lugs or a connector on the other end for attachment to a power distribution block or PDU.

   • Length: The part number suggests a length of 5 meters (the "05000" likely indicates 5000 mm). This standard length provides flexibility for routing within a cabinet or between adjacent cabinets.

   • Shielding & Gauge: The cable is built with a sufficient wire gauge to handle the current requirements of the MU and is well-shielded for safety and to prevent interference.

Deployment Scenarios

• New Site Installation: Used when installing a new Ericsson base station cabinet to provide power to the main control unit.

• Maintenance/Replacement: A critical spare part for replacing a faulty or damaged power cable during maintenance operations without disrupting the entire power system.

Troubleshooting & Notes

• Power Failures: If an MU unit fails to power on, this cable is one of the first components to check. Ensure both ends are securely connected.

• Safety: Always ensure the DC power source is switched off before connecting or disconnecting this cable.

• Genuine Part: Using a genuine Ericsson cable ensures proper fit, electrical characteristics, and safety compliance.

Purchasing & Availability

• Status: This is a standard spare part for Ericsson base stations.

• Price Range: Typically between $50 - $150, depending on the supplier and whether it is new or refurbished.

• Suppliers: Available from specialized telecom equipment distributors such as:

  • Skyward Telecom

  • Zhongtian Nuoda

  • Various vendors on eBay and Alibaba.

Important Consideration: When purchasing, verify that the connector type matches your specific Ericsson MU model.

Conclusion

The RPM 777 298/05000 is a fundamental component for powering Ericsson base station equipment. Its reliability is crucial for the continuous operation of the cellular site. Ensuring you have a genuine, well-manufactured cable is a simple but essential step in maintaining network uptime.
