EXTREME NETWORKS 5120-44X-4Y-2C-AC-F - Layer 2/3 Universal Ethernet Switch
Overview
The EXTREME NETWORKS 5120-44X-4Y-2C-AC-F is an enterprise-grade, high-density 10 Gigabit fiber aggregation switch custom-engineered for modern campus edge stacks, heavy-utilization distributed corporate closets, and localized high-performance Internet of Things (IoT) terminal collections. This universal hardware platform resolves the deployment bottlenecks associated with routing high-bandwidth video encoders, medical imaging arrays, and dense data links by delivering cost-optimized, line-rate physical layer consolidation. It establishes automated operational readiness across large business facilities and multi-tier networks requiring scalable, low-latency fiber concentration.
The physical architecture centers on a 1RU fixed chassis featuring 44 unpopulated 1G/10Gb SFP+ optical access ports paired alongside 4 dedicated 10G/25Gb SFP28 uplink interfaces. To eliminate upstream performance constraints, the layout incorporates 2 native, high-capacity 100Gb QSFP28 structural ports that can be utilized as high-speed uplinks or bound into a resilient hardware stacking loop. This specific AC-F configuration ships pre-packaged with 6 hot-swappable cooling fans running a specialized front-to-back forced airflow profile, driven by a single 550W AC modular power supply unit while leaving a secondary power bay open for field-replaceable electrical redundancy.
Engineered for unified cloud-managed or on-premises administration, the system interfaces natively with ExtremeCloud IQ and Extreme Platform ONE, facilitating zero-touch deployment (ZTP) and automated port configuration changes via instant port profiles. The underlying hardware is optimized to support line-rate 256-bit AES MACsec cryptographic encryption across all physical interfaces to safeguard corporate point-to-point links against active extraction or intercept attempts. Avoid deploying this fiber-only access node in multi-drop copper topologies requiring native twisted-pair RJ-45 connectivity, or in high-draw industrial settings requiring direct IEEE 802.3bt Power over Ethernet power injection from the switch chassis.
Key Features
44 dedicated SFP+ fiber ports provide high-density 10Gb aggregation capacity.
Dual 100Gb QSFP28 interfaces handle massive upstream bandwidth or stacking lines.
Four fixed SFP28 slots extend flexible 10G/25G long-range uplink coverage.
Hot-swappable dual PSU architecture enables hitless secondary AC provisioning.
Automated central provisioning via ExtremeCloud IQ eliminates local manual setup.
