Managing the Complexity of a Telecommunication Power Systems Equipment Replacement Program

Telecommunication operators must manage many types and models of power equipment from many manufacturers each with different characteristics. With Telco's globally reporting strong pressure on CAPEX reduction, it is important to develop capability not only of predicting end-of-life of equipment, but also of managing the vast number of types, makes and models used in a variety of environments. Delayed replacement results in higher service disruption risk while early replacement places considerable pressure on CAPEX budgets. We have developed an Equipment Reliability Analysis (ERA) program for telecommunication power equipment life cycle replacement. Rectifiers, batteries and UPS life data are grouped by features including technology, manufacturer make/model, life-data analysis from field failure data, and equipment tear-down analysis for life cycle replacement decisions. Replacement decisions are based on a number of inputs, including field experience, type of application, defect data and life data analysis.
