Alcatel-Lucent 3AL97237AB 1642 EMC Chassis DC-48V

The Alcatel-Lucent 3AL97237AB 1642 EMC Chassis DC-48V is a ruggedized equipment enclosure engineered for housing and interconnecting line cards, service interface boards, cross-connect modules, control units, power supply units, and fan modules in the 1642 Extended Metro Core (EMC) optical transport network platform. This chassis provides the mechanical infrastructure, backplane connectivity, power distribution, and thermal management foundation for SDH/SONET and packet-optical transport applications in metro access, aggregation, and core network deployments. The 1642 EMC chassis implements a modular slot-based architecture with multiple card slots supporting various interface types including STM-1/OC-3, STM-4/OC-12, STM-16/OC-48, Gigabit Ethernet, and Fast Ethernet services with flexible configuration options optimized for scalable network growth. The chassis features integrated −48 V DC power distribution system with redundant power feed inputs, overcurrent protection, voltage regulation, and power monitoring capabilities ensuring reliable operation per telecommunications standards. Advanced features include high-speed backplane connectivity providing serial links between installed modules for data transport, control plane communication, timing distribution, and management traffic; integrated grounding and bonding points for electromagnetic compatibility (EMC) compliance and lightning protection; forced-air cooling system with fan tray mounting locations and optimized airflow paths ensuring thermal management of installed modules; cable management features including strain relief points, routing guides, and bend radius control for fiber and copper cabling; and comprehensive EMI/RFI shielding with conductive gaskets and filtered ventilation maintaining electromagnetic compatibility per EN 300 386 and FCC Part 15 Class A standards. The chassis implements robust mechanical construction with powder-coated or anodized aluminum/steel frame providing structural integrity, corrosion resistance, and durability for long-term deployment. Installation features include compatibility with standard 19-inch rack mounting systems per EIA-310-D and IEC 60297 specifications, front and rear access configurations for flexible deployment scenarios, integrated handles and lifting points for safe installation and maintenance, and alignment guides ensuring proper module insertion and backplane connector engagement. The chassis supports hot-swappable module installation enabling field replacement of line cards, power supplies, and fan units without service disruption. Management interfaces include backplane connectivity to shelf controllers for integrated monitoring of temperature, fan speed, power consumption, and module status through SNMP v3, TL1, and proprietary element management system protocols compatible with Alcatel-Lucent's 1350 OMS. 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 from 5% to 95% non-condensing. The 1642 EMC Chassis is validated for deployment in Alcatel-Lucent optical transport networks and ensures compliance with ETSI EN 300 119, Telcordia GR-487, IEC 60917, EIA-310, NEBS GR-63, and ITU-T G.783 standards for telecommunications equipment mechanical infrastructure, environmental protection, electromagnetic compatibility, and operational reliability.
