Extreme 4120-24MW-4Y 4000 Series Multi-Gig PoE Switch 24-Port 90W PoE++ 4x25GbE Uplinks High-Density Campus Edge Network

Next-Generation Edge Performance with Extreme 4120-24MW-4Y

The Extreme 4120-24MW-4Y Multi-Gig PoE Switch provides a high-density solution for modern enterprise environments. It specifically addresses the needs of high-speed wireless access points and bandwidth-heavy IoT devices. This hardware removes traditional 1Gbps bottlenecks at the edge of your network.

You get 24 ports that support 100M, 1G, 2.5G, and 5G speeds. This flexibility allows you to upgrade your cabling and devices incrementally without replacing your entire switching fabric. The auto-negotiation technology ensures that every connected device runs at its maximum capable speed.

Reliability is built into the core of the 4000 Series architecture. These switches support redundant power supplies to maintain uptime in critical environments. If you are looking for an Extreme Networks dealer, distributor, and reseller in India, this model offers the best balance of power and port density for campus deployments.

Advanced Power Delivery for High-Demand Devices

Modern hardware requires more than just standard PoE. This switch provides 802.3bt PoE++ delivering up to 90W per port. This power level is necessary for high-end PTZ cameras, large display screens, and Wi-Fi 7 access points.

The total PoE budget is managed intelligently to prevent oversubscription. You can prioritize critical ports to ensure that vital security or communication hardware never loses power. This eliminates the need for expensive and cluttered midspan power injectors.

Heat management is handled by high-efficiency internal fans. This ensures the switch remains stable even when delivering maximum power to all 24 ports simultaneously. The compact 1U form factor makes it easy to install in standard server racks or wall-mount cabinets.

High-Speed 25GbE Uplinks and Stacking

Backhaul congestion can ruin the performance of even the fastest edge ports. The Extreme 4120-24MW-4Y Multi-Gig PoE Switch includes four SFP28 uplink ports. These ports support both 10GbE and 25GbE speeds depending on your transceiver choice.

These high-speed links ensure that traffic from multi-gigabit clients moves to the core network without delay. You can also use these ports for high-speed stacking. Stacking allows you to manage multiple switches as a single logical unit.

Up to eight units can be stacked together. This creates a highly resilient system with a single management IP address. Configuration changes and firmware updates propagate across the stack automatically, saving significant administrative time.

Cloud-Native Management and Security

Security starts at the physical layer with this switch. It supports hardware-based MACsec encryption on both access and uplink ports. This prevents unauthorized data interception and man-in-the-middle attacks within your local infrastructure.

Management is simplified through ExtremeCloud IQ. This platform provides deep visibility into device health and client performance. You can monitor traffic patterns and troubleshoot connectivity issues from a single web-based dashboard.

The switch also supports automated fabric attachments. This allows you to extend your network fabric to the edge without manual VLAN tagging. Devices are automatically assigned to the correct network segment based on their identity and role.

Optimizing for Modern Campus Networks

Campus networks are changing as more users move to wireless-first connectivity. The Extreme 4120-24MW-4Y Multi-Gig PoE Switch provides the infrastructure needed to support these users. It bridges the gap between old 1G copper and new fiber-speed wireless standards.

Deploying this switch reduces the complexity of your wiring closet. You can run data and high-wattage power over a single Category 6A cable. This reduction in cabling lowers installation costs and improves airflow in tight spaces.

Finally, the switch is designed for longevity. The hardware specs exceed current common requirements, giving you several years of headroom. It is a stable investment for any IT team focused on future-proofing their infrastructure.
