Alcatel-Lucent 3AL92156ABAA 1/2 Slot Dummy Plate

The Alcatel-Lucent 3AL92156ABAA is a 1/2 slot dummy plate (blank panel) engineered for filling unused equipment slots in SDH/SONET transport platform shelves and racks compliant with ANSI and ETSI mechanical standards. This mechanical component provides electromagnetic interference (EMI) shielding, airflow management, and physical protection for empty slots in 19-inch rack-mountable transport equipment enclosures including the 1650SM, 1660SM, 1670, 1696MS, and related Alcatel-Lucent optical transport platforms. The dummy plate features precision-machined aluminum or steel construction with conductive finish ensuring proper electromagnetic compatibility (EMC) compliance per EN 300 386 and FCC Part 15 Class A standards. The 1/2 slot width designation (approximately 0.42 inches or 10.67mm) allows efficient utilization of shelf real estate when filling half-height module positions or when combining with other blank panels to fill full slot positions. The plate implements integrated EMI gasketing along the perimeter edges providing continuous electrical contact with the shelf chassis to prevent electromagnetic leakage and maintain shield integrity of the equipment enclosure. Advanced features include captive screw fasteners or quarter-turn latches for secure installation and tool-less or minimal-tool removal, integrated handles or finger grips for safe installation and extraction, and alignment guides ensuring proper positioning within the slot. The dummy plate supports proper airflow management by preventing uncontrolled air bypass through empty slots, ensuring optimal cooling of installed active modules and maintaining designed thermal performance of the transport shelf. Installation features include compatibility with standard 19-inch rack systems per EIA-310-D and IEC 60297 specifications, ANSI and ETSI mechanical standards for telecommunications equipment, and Alcatel-Lucent proprietary shelf mounting systems. The panel features durable powder-coated or anodized finish providing corrosion resistance and aesthetic consistency with other shelf components. Environmental specifications comply with ETSI EN 300 019 Class 3.1 and NEBS GR-63 Level 3 standards, supporting operation in controlled telecommunications facilities with ambient temperatures from 0 °C to +45 °C and relative humidity up to 95% non-condensing. The 1/2 Slot Dummy Plate is validated for deployment in Alcatel-Lucent 1650SM/1660SM/1670/1696MS/1830/1850 series transport platforms and ensures compliance with ETSI EN 300 119, Telcordia GR-487, IEC 60917, and EIA-310 standards for telecommunications equipment mechanical infrastructure and electromagnetic compatibility.
