Alcatel-Lucent 3HE01473AAAB01 7750 SR IOM 2 LINE Card 20G

The Alcatel-Lucent 3HE01473AAAB01 7750 SR IOM 2 (Input/Output Module 2) LINE Card 20G is a high-performance interface module engineered for versatile network connectivity and packet processing in Nokia (formerly Alcatel-Lucent) 7750 Service Router platforms for carrier-grade IP/MPLS network infrastructure. This second-generation IOM module provides 20 Gbps aggregate forwarding capacity with support for multiple interface types including Fast Ethernet, Gigabit Ethernet, and channelized interfaces for flexible service delivery in telecommunications service provider, enterprise, and data center environments. The IOM 2 LINE Card implements advanced packet processing functionality including Layer 2 switching, Layer 3 routing, MPLS label operations, quality of service (QoS) enforcement, access control lists (ACLs), and traffic management optimized for mobile backhaul, business services, Internet access, and data center interconnect applications. The module features multiple interface slots supporting Small Form-factor Pluggable (SFP), Enhanced Small Form-factor Pluggable (SFP+), or RJ-45 transceivers for flexible connectivity to diverse network infrastructures including copper and fiber optic media. Advanced features include distributed forwarding architecture with local packet processing to reduce latency and increase throughput, hierarchical quality of service (H-QoS) with multiple scheduling algorithms (strict priority, weighted fair queuing, deficit round robin), traffic policing and shaping per committed information rate (CIR) and peak information rate (PIR) parameters, comprehensive access control with hardware-accelerated ACL processing, and support for jumbo frames up to 9216 bytes. The IOM 2 implements sophisticated buffer management with dynamic buffer allocation, congestion avoidance mechanisms, and multicast replication engines for efficient bandwidth utilization. Integration with the 7750 SR chassis backplane provides high-speed connectivity to switch fabric modules, routing engines, and control processors for coordinated network operation and centralized management. The module supports hot-swappable design enabling field replacement without service disruption to the routing platform, with automatic module detection, configuration restoration, and traffic redistribution upon insertion or removal. Management interfaces include connectivity to the system control processors through the chassis backplane for centralized module management, performance monitoring, fault detection, and integration with the router's operations, administration, and maintenance (OAM) framework through SNMP v3, NETCONF/YANG, RESTful APIs, and proprietary element management system protocols compatible with Nokia's Network Services Platform (NSP), 5620 Service Aware Manager (SAM), and third-party network management systems, providing access to interface statistics, buffer utilization, QoS counters, error rates, temperature readings, alarm status, and diagnostic information. The IOM 2 LINE Card implements comprehensive operations, administration, and maintenance (OAM) capabilities including Bidirectional Forwarding Detection (BFD), Ethernet OAM (802.3ah/802.1ag/Y.1731), MPLS OAM, loopback testing, and link trace for proactive fault detection and service level agreement (SLA) verification. Power is distributed via the chassis backplane from redundant −48 V DC or AC power supply units with integrated voltage regulation, current monitoring, overcurrent protection, and intelligent power management. The module features robust electromagnetic compatibility (EMC) design per EN 300 386, FCC Part 15 Class A, and CISPR 32 standards with integrated shielding and filtering to prevent electromagnetic 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 (with derating above 40 °C) and relative humidity from 5% to 95% non-condensing. The 7750 SR IOM 2 LINE Card 20G is validated for deployment in Nokia 7750 SR-12, 7750 SR-7, 7750 SR-1, and related service router platforms requiring second-generation input/output modules, and ensures compliance with IEEE 802.1/802.3 standards, IETF RFC specifications, ITU-T Y.1731/G.8031/G.8032, MEF specifications, MPLS Forum standards, Telcordia GR-63/GR-1089 (NEBS), RoHS/WEEE directives, and CE/FCC marking requirements for carrier-grade interface modules in telecommunications service provider and enterprise network infrastructure.
