Switch ZYXEL GS1920-24HPV2, 24 port Gigabit Smart-Managed PoE, for rack mounting

ZYXEL GS1920-24HPV2 is a 24-port Gigabit Smart-Managed PoE switch aimed at serious small and medium networks, offices, and locations with PoE devices – cameras, access points, IP phones. You get a combination of 24x 100/1000Mbps PoE ports plus 4x Gigabit combo (RJ-45/SFP) for uplink or optical connections, all in a rack-mountable chassis. The high maximum consumption of 463.5W suggests a stable PoE capacity for many devices simultaneously. Management and security are top-notch, with a host of access control and filtering features by MAC, IP, and ports.

What you get

The main advantage here is flexibility – 24 PoE ports allow you to directly power IP cameras, access points, and phones without separate adapters, while the 4 combo Gigabit ports provide options for connecting to other switches or optical infrastructure. A table with 16K MAC addresses means the switch can easily handle larger and segmented networks without “forgetting” devices. Support for IEEE 802.3af / 802.3at ensures compatibility with PoE and PoE+ devices, which is important for more power-hungry access points or PTZ cameras. The powerful level of security – 802.1X, RADIUS, TACACS+, ACLs, and DHCP snooping – gives you tools to keep the network under control, especially in environments with many users or guests. Management with IPv6, dual stack, and various RFC standards facilitates integration into modern, mixed IPv4/IPv6 infrastructures.

• You have 24x 100/1000Mbps PoE ports, allowing direct powering and connecting dozens of PoE devices from a single switch.
• You have 4x Gigabit combo (RJ-45/SFP) ports for flexible uplink connections – copper or optical, depending on the needs of the network.
• Maximum consumption of 463.5W provides a serious PoE budget for multiple devices powered simultaneously.
• A table with 16K MAC addresses allows stable operation in larger and segmented networks without scaling issues.
• A rich set of security features – from 802.1X, Port security, DHCP snooping (IPv4/IPv6), ACL packet filtering to RADIUS/TACACS+ – gives fine control over access.
• Management with IPv6 over Ethernet, dual stack, ICMPv6, DHCPv6 relay, and Neighbor discovery makes it ready for modern IPv6 networks.
• Designed for rack mounting and with incoming power 100–240V AC, 50–60Hz, the switch easily fits into standard server or communication racks.
• A long warranty of 60 months provides peace of mind for reliability in a professional environment.

Who it is suitable for

This switch is suitable if you are building or expanding an office network, video surveillance, or Wi-Fi infrastructure with many PoE devices and want centralized management and a serious set of security features. It is also suitable for corporate and educational environments where RADIUS/TACACS+ authentication and VLAN policies are mandatory. It is not the most logical choice if you only need a simple, cheap unmanaged switch for 2-3 devices at home.

The combination of 24 PoE ports, 4 flexible combo uplinks, a rich security package, and support for IPv6 makes ZYXEL GS1920-24HPV2 a stable core for a serious network infrastructure that you can upgrade confidently for years to come.
