Includes dual power supplies, hot-swappable modules, link aggregation (LAG), and support for HSRP/VRRP. Modular chassis or stackable designs make it easy to scale as your network grows. Supported from Cisco IOS XE Gibraltar 16. All the switches ship with a blank cover in the second power supply slot if the switches are ordered with only one power supply module. For information about available PoE and PoE+ requirements, see these sections the Power Supply Modules. The power. The Dual Power Supply Ethernet Switches with 10 GE SFP+ Ports offer high-speed access for dense server setups or as a core switch in campus networks, supporting up to 40 Gbps. It features dual power supply, more than 48 ports, and advanced functionalities like LACP, PoE, QoS, SNMP, and VLAN. Generally, multiple data switches are used at the core layer of a network so that a large amount of data can be routed to the layers in the hierarchy. Sitting at the top of the hierarchical model, core switches interconnect distribution layer switches and provide high-speed data transfer across. Description: EX3300 Ethernet Switches are flexible, cost-effective enterprise access solutions for campus and data center environments. A compact, scalable switching solution, the EX3300 supports converged data, voice, and video, with models that come with 24 or 48 10/100/1000BASE-T ports. If you're looking for the best enterprise core switches for 2026, I recommend considering options like the Cisco Catalyst 9300L with PoE+, the Cisco C9500-16X-A with dual PSUs, the M4300-12X12F managed switch, NETGEAR's 48-port managed switch, the Edge-Core 5610-52X, T-Plink's 48-port PoE solution.
