TP-Link Omada SG3428XPP-M2 network switch 24 × 2.5G PoE 500 W, 4 × 10G SFP+

All 24 RJ45 ports run at up to 2.5 Gbit/s and remain compatible with 100 Mbit/s and 1 Gbit/s devices. A multi-gigabit port makes sense for newer Wi-Fi access points whose wireless speed exceeds one gigabit, and for workstations and NAS units fitted with a 2.5G network card. You can upgrade the network step by step, because older gigabit devices keep working on the same ports.

Eight ports support the PoE++ standard (IEEE 802.3bt) and deliver up to 60 W, while the other sixteen are PoE+ ports with up to 30 W. The total PoE budget is 500 W. PoE++ is meant for devices that need more than 30 W, such as higher-draw access points or pan-tilt cameras. One switch can therefore power the access points and cameras of an entire floor without extra power supplies, as long as the total stays within budget.

When 24 ports move 2.5-gigabit traffic at the same time, the link to the rest of the network has to be fast too. The four 10G SFP+ slots are suited to connecting a server, NAS or core switch, and links can be aggregated for even more bandwidth. Switching capacity is 200 Gbit/s, the forwarding rate is 148.8 million packets per second and the MAC address table holds 32,000 entries.

Static routing with up to 48 routes and 32 IP interfaces moves traffic between VLANs directly on the switch. Stacked VLAN, voice VLAN and MAC-based or protocol-based VLANs are supported. User access is controlled by 802.1X together with RADIUS and TACACS+ servers, IP-MAC-Port binding, DHCP snooping and ARP inspection block spoofing attacks, and ACLs filter traffic at both IPv4 and IPv6 level.

ERPS quickly restores connectivity in a ring topology if one of the links fails. The three fans are redundant and the switch supports a redundant power supply (RPS). It can be managed from the Omada cloud via web or app, or standalone through the web interface, command line, SNMP v1/v2c/v3 and RMON, and for initial setup there is a console port with both RJ-45 and micro-USB connectors. Maximum power consumption is 629.1 W and the operating range is 0 to 40 °C.

Businesses moving their office Wi-Fi to newer multi-gigabit access points; schools, hotels or warehouses where dozens of access points and cameras are powered from one cabinet; IT administrators who need VLANs, 802.1X authentication and static routing; and networks whose backbone already runs at 10 Gbit/s.
