ExtremeSwitching X435-24P-4S Ethernet Switch

The ExtremeSwitching X435-24P-4S is an economical, purpose-built edge switch designed for distributed enterprises, branches, and small sites. This 24-port PoE-enabled switch combines value-forward performance with straightforward management, delivering reliable connectivity for IP phones, wireless access points, cameras, and other edge devices. Built to support cost-conscious deployments, the X435-24P-4S provides flexible uplink options, solid security, and efficient operation—making it an ideal solution for sites that require a scalable, enterprise-grade data path without breaking the budget.

• Designed for distributed enterprises and branch offices, the X435-24P-4S delivers dependable Layer 2 switching with 24 PoE+ Ethernet ports and 4 SFP uplink ports. This combination enables direct power delivery to IP cameras, VoIP phones, and wireless access points while preserving high-bandwidth interconnectivity to the core network. The PoE+ support simplifies deployments by eliminating separate power infrastructure for edge devices, reducing cabling clutter, and accelerating rollout in multi-site environments. The 4 SFP uplinks provide flexible fiber connectivity to distribution switches or aggregation switches, enabling scalable topologies that grow with your business needs.
• Value-driven edge performance with enterprise-grade features. The X435-24P-4S is engineered to handle the traffic patterns of small to mid-sized sites, offering robust VLAN support, fast MAC learning, and efficient QoS to ensure voice and video traffic get the priority they require. With industry-standard security capabilities—such as ACLs, access control measures, and foundational 802.1X authentication—the switch helps protect wired network access while supporting policy-based segmentation. Its resilient design and straightforward management mean you can deploy quickly and rely on consistent, predictable performance as your site grows.
• Flexible management and streamlined operations. This Extreme Networks edge switch can be configured and monitored through a user-friendly web-based interface and a command-line interface, providing administrators with both intuitive day-to-day controls and deeper, scriptable configuration options. The X435-24P-4S supports standard management protocols and monitoring, enabling integration with existing network management systems. Its straightforward provisioning workflows enable zero-touch deployment in branch sites and allow IT teams to push consistent configurations across multiple devices, simplifying administration across a distributed footprint.
• Security and quality of service that keep business critical traffic moving. Enterprises rely on reliable, predictable behavior for IP telephony, critical applications, and streaming video. The X435-24P-4S implements VLAN isolation, ACLs, and QoS policies to separate and prioritize traffic, while controls such as DHCP snooping and port security help mitigate common attack vectors at the edge. The combination of these capabilities supports secure guest access, segregated management traffic, and reliable performance for voice and video services, even in environments with guest devices or fluctuating network loads.
• Energy efficiency, compact form factor, and quiet operation for office environments. The X435-24P-4S is designed for space-constrained deployments, with a compact footprint suitable for rack-mounting or shelf deployment in small data closets. Its energy-conscious design minimizes power consumption during idle periods while delivering full PoE performance when devices demand power. The switch’s cooling and thermal characteristics are tuned for silent or near-silent operation in open office spaces, conference rooms, or branch closets, helping to maintain a distraction-free work environment while keeping network devices powered and connected.
