Frequently asked questions about this product
What PoE budget does the ZyXEL GS1920-24HPV2 offer?
375 W in total, across its 24 ports, to the PoE+ 802.3at standard (30 W maximum per port). This is a comfortable budget: it can power all 24 sockets with cameras and phones, or a dozen more power-hungry devices.
What are the 4 combo ports on this switch for?
They are uplinks that can be used with SFP fibre or RJ45 copper, as you choose, but not both at the same time on the same slot. They connect the switch to the network core, to another building or to a server.
What level of management does this switch offer?
Layer 2 management via a web interface, with SNMP monitoring. VLANs, quality of service and device monitoring are therefore accessible from a browser, without using a command line.
Is the GS1920-24HPV2 ready for IPv6?
Yes, it is IPv6 compatible. Moving to this addressing scheme therefore does not require replacing the switch, which matters for an access device meant to stay in place for several years.
How much power should you allow for this switch?
Up to 463.5 W, once the 375 W of PoE is being delivered to devices. This is the figure to use when sizing the UPS and the rack ventilation, not the idle consumption.
How much rack space does this switch take up?
440 × 270 × 44 mm and 3.8 kg, i.e. 1U high and 27 cm deep. It is designed for 19-inch rack mounting; a shallow wall-mount cabinet will not be enough.
Is the switch new and covered by a warranty?
Yes, new equipment, with the invoice serving as the warranty document. This is the ZyXEL GS1920-24HPV2, reference GS192024HPV2-EU0101F.
Designed for video surveillance: a 384 W PoE+ budget shared across the powered ports, transmission up to 250 m and power maintained even when the switch restarts. Rackable metal housing, VLAN and automatic loop prevention.
•Total PoE+ budget of 384 W, up to 30 W per port (802.3af/at)
•2 Gigabit SFP ports for a fibre link
•Fast PoE and Perpetual PoE: power maintained when the switch restarts
A managed enterprise switch that powers IP cameras, Wi-Fi access points and phones on every one of its ports, with no mains socket. Switching capacity 176 Gbps, stackable, upgradable to fibre.
Layer 3 managed enterprise switch (static routing and RIP) that powers all its ports over the network cable, for cameras and Wi-Fi access points. Switching capacity 128 Gbps, upgradable to 10 Gbps fibre.
Managed access switch designed for SMEs and branch offices: powers workstations, Wi-Fi access points and IP cameras over Power over Ethernet, with centralised control from Aruba Central and automated deployment.
•Managed via Aruba Central (cloud or on-premise), web GUI, CLI and REST API
•PoE+ up to 30 W per port (IEEE 802.3af/at, class 4)
Fast PoE instantly powers cameras, Wi-Fi access points and IP phones over the network cable, with no break on restart. Four 10G links absorb traffic to the network core. Web, cloud app or command line control, built-in DoS/802.1X security.
Managed switch that powers its ports over PoE+ through the network cable, with two 2.5 Gbps combo ports for recent Wi-Fi access points. Configurable through the HUAWEI eKit App cloud or locally.
Cisco Catalyst 2960-X managed switch with LAN Base image: 24 Gigabit PoE+ ports with a 370 W budget, 4 SFP 1 Gbps uplink ports and FlexStack-Plus stacking of up to 8 switches. 1U, 5.8 kg, for a 19-inch rack.
Covers a whole floor of cameras, Wi-Fi access points and IP phones on a single device, without multiplying power units. 10G links and a capacity of 176 Gbps absorb the combined traffic. VLANs, security and administration of enterprise equipment.
Designed for SMEs and video surveillance, in a 19″ rackable format: automatic IP camera recognition, PoE consumption alarm and remote port restart through Ruijie Cloud.
