Enterasys A2H254-16 P0973BK: Name and Description

1. Name

2. Core Description

• Product Positioning: As a key member of Enterasys’ A2 Series access switches (now part of Extreme Networks’ portfolio following acquisition), this switch is designed for enterprise and industrial network access layers. It focuses on providing high-speed, reliable Gigabit Ethernet connectivity and PoE (Power over Ethernet) capabilities to end devices, serving as a critical hub for connecting computers, IP cameras, wireless access points (WAPs), and IoT devices in office buildings, retail stores, industrial facilities, and campus networks.
• Key Functions & Features:
• Gigabit Port Configuration: Equipped with 16 x 10/100/1000BASE-T copper ports (for end-device connectivity) and typically 2 x 1 Gigabit SFP uplink ports (for high-speed connection to core/aggregation switches). This configuration balances local device access and uplink bandwidth, avoiding network bottlenecks.
• PoE+ Compliance: Supports IEEE 802.3af/at (PoE+) standards, delivering up to 30W of power per PoE port. The total PoE power budget (typically 370W for this model, subject to official specs) enables simultaneous power and data transmission to PoE-enabled devices, eliminating the need for separate power cables and reducing installation costs.
• Layer 2+ Managed Capabilities: Offers full Layer 2 switching functions (VLAN, QoS, Link Aggregation, Spanning Tree Protocol/Rapid Spanning Tree Protocol) and basic Layer 3 features (static routing, IPv4/IPv6 support). These capabilities allow network administrators to segment traffic, prioritize critical data (e.g., video surveillance streams), and enhance network stability and security.
• Industrial-Grade Reliability: Built with a ruggedized design to withstand harsh operating conditions—including wide temperature ranges (often -40°C to +60°C), resistance to shock and vibration, and compliance with industrial EMC (Electromagnetic Compatibility) standards. This makes it suitable for both enterprise and light industrial environments (e.g., manufacturing floors, outdoor kiosks).
