Extreme Networks 45112 BlackDiamond 8800 GM-4Xi Interface Module

The Extreme Networks 45112 (GM-4Xi) is a high-performance Gigabit Ethernet interface module designed for the BlackDiamond 8800 series modular switching platform. It features four unpopulated SFP (Small Form-factor Pluggable) slots, providing flexible fiber optic or copper connectivity options for core and aggregation layers. This module is engineered to deliver wire-speed performance across all ports, supporting a wide range of standard SFP transceivers, including 1000BASE-SX, LX, and ZX. The GM-4Xi is optimized for enterprise-class data centers and carrier-grade environments where high-density, low-latency Gigabit connectivity and modular scalability are required.The module utilizes the advanced ExtremeXOS modular operating system, enabling comprehensive Layer 2 and Layer 3 functionality, including advanced routing, Quality of Service (QoS), and granular security policies. Each port supports hardware-based Access Control Lists (ACLs) and sophisticated traffic management features to prioritize mission-critical data such as Voice over IP (VoIP) and video streaming. The hardware architecture ensures high availability through integrated link aggregation (802.3ad) and support for EAPS (Ethernet Automatic Protection Switching) for resilient ring topologies. Its internal switching fabric interface is designed to prevent bottlenecks, ensuring consistent throughput even under heavy network loads.
Designed for long-term reliability and ease of maintenance, the 45112 is fully hot-swappable, allowing for installation or removal from the BlackDiamond 8800 chassis without interrupting system operation. The module includes a comprehensive set of front-panel LED indicators for real-time link status and activity monitoring for each individual port. It is built with a robust mechanical design that ensures proper alignment and grounding within the chassis backplane. The GM-4Xi is compliant with international safety and electromagnetic compatibility (EMC) standards, providing a stable and standardized interface for expanding the capabilities of modular core switches.
