Alcatel-Lucent 3AL86652AB AA02 PSC3 Power Interface Board

The Alcatel-Lucent 3AL86652AB AA02 PSC3 is a power interface board engineered for advanced power distribution, monitoring, and control in optical transport network platforms for SDH/SONET and packet-optical architectures. This module provides intelligent power management functionality including redundant −48 V DC power feed distribution, voltage regulation, current monitoring, and load balancing across multiple shelf sections in the 1696MS and related transport platform enclosures. The PSC3 (Power Supply Controller 3) card implements comprehensive power management features with automatic load sharing between redundant power feeds, overcurrent protection with resettable circuit breakers, overvoltage protection, undervoltage detection, reverse polarity protection, and hot-swappable design enabling field replacement without service disruption. Advanced features include per-rail voltage monitoring, output current measurement, temperature sensing, power good status indication, power sequencing control, and alarm reporting for undervoltage, overvoltage, overcurrent, overtemperature, and power feed failure conditions. The module supports intelligent power budgeting and distribution to installed line cards, service interface boards, cross-connect modules, main processing units, and other shelf-resident equipment with dynamic power allocation based on module requirements. Integration with the transport shelf backplane provides high-current power distribution paths and communication with the system control processor through I²C, SMBus, or PMBus interfaces for remote monitoring and management. Management interfaces include SNMP v3, TL1, and IPMI-compatible protocols for integration with Alcatel-Lucent's 1350 OMS, NuWave EMS, and third-party network management systems, providing access to input voltage levels, output current readings, temperature sensors, power consumption statistics, and alarm conditions. The module features robust electromagnetic compatibility (EMC) filtering per EN 300 386 and FCC Part 15 Class A standards to prevent conducted and radiated interference. Environmental specifications comply with ETSI EN 300 019 Class 3.1 and NEBS GR-63 Level 3 standards, supporting continuous operation in controlled telecommunications facilities with ambient temperatures from 0 °C to +45 °C and relative humidity up to 95% non-condensing. The PSC3 is validated for deployment in Alcatel-Lucent 1696MS/1650SM/1660SM/1670 series transport platforms and ensures compliance with Telcordia GR-487, ETSI EN 300 132, and NEBS GR-487 standards for telecommunications power systems and distribution equipment.
