Build a managed network with 24 10/100/1000 Mbps RJ45 PoE-enabled ports and four open 10G SFP+ slots for uplinks. The 370 W PoE power budget provides up to 30 W per port for IEEE 802.3af and IEEE 802.3at devices, including wireless access points, VoIP phones, and IP cameras. Auto-sensing Ethernet ports support automatic speed negotiation, while Auto-MDIX simplifies connections. This Layer 2+/Layer 3 Lite switch supports Web browser, SNMP, RMON, Telnet, SSH, and RJ45 console configuration. Network controls include VLAN, link aggregation and trunking, port mirroring, bandwidth control, IGMP Snooping, broadcast storm control, jumbo frames up to 12 kBytes, and QoS with CoS or DSCP. IPv4 and IPv6 dual-protocol support, LLDP, DHCP snooping, access management filtering, and up to 16,000 MAC address entries support flexible network administration. The Powered Device Monitor self-healing function checks connected PoE devices and restarts devices that fail to respond or send network traffic. IEEE 802.3at/af detection provides short-circuit, overload, and high-voltage protection. IEEE 802.3az Energy Efficient Ethernet and Green Ethernet technology reduce power use by deactivating unused ports and adjusting power levels based on cable length. A 128 Gbps switching capacity, 95.23 Mpps forwarding rate, store-and-forward architecture, two cooling fans, grounding point, and included 19-inch rackmount brackets support installation in managed office, surveillance, VoIP, and network environments.
