Cloud-Managed Switch for SMB Networks

The ZyXEL GS1920-24V2 is a rack-mountable smart managed switch built for small and medium businesses. It delivers 24 Gigabit Ethernet ports and four SFP combo uplinks for fibre or copper uplinks. The unit supports Layer 4 switching and NebulaFlex cloud management, allowing instant transition between standalone and cloud modes without licences. Power draw is 27.20 W under typical load.

Ideal for Growing Offices.

This switch suits administrators who want quiet, fan-optimised operation and simple cloud oversight across multiple sites. It fits standard racks and runs on an internal power supply. Buyers who need PoE on every port or higher uplink speeds should look elsewhere, as the spec provides 24 ports without PoE and 1 Gbps uplinks only. The 4.63 lb weight eases single-person installation.

NebulaFlex Licence-Free Cloud Management

The defining specification is NebulaFlex, which lets you move between local GUI control and the Nebula cloud platform at any time with no subscription cost. This flexibility means the same hardware adapts to changing management policies without replacement. Combined with Layer 4 capability and 28 total ports, it future-proofs the access layer for expanding SMB networks.

  • 28 total ports including 4 SFP uplinks for fibre expansion
  • Layer 4 switching capability for advanced traffic control
  • 24 PoE ports power devices without separate adapters

Questions about this item

How many PoE devices can the GS1920-24V2 power before the 27.20 W budget is exhausted?

How loud is the GS1920-24V2 when it runs continuously in a rack?

The GS1920v2 series uses a smart fan design for whisper-quiet operation, keeping noise low during all-day use.

Which SFP transceivers must I already own to use the four uplink ports on the GS1920-24V2?

The four combo ports accept standard SFP (mini-GBIC) modules for 1000Base-X fiber or copper uplinks.
