Overview:
The Zyxel GS1915v2 Series features nine Gigabit Smart Managed Switches ranging from 8 to 26 ports, designed for SMBs, retail, hospitality, and lightindustrial environments. Featuring NebulaFlex, the series allows you to choose between Nebula cloud management and intuitive standalone web management. Built for diverse deployment scenarios, the portfolio includes fanless desktop and wall-mount models, smart-fan rack-mount switches, and a rugged DIN-rail switch with dual AC/DC power redundancy. PoE+ models offer power budgets from 60W to 180W, delivering reliable power and connectivity for a wide range of business applications.
Affordable cloud switch with plug and play simplicity
Multiple choices and comes with SFP ports support fit in various applications for SB/SMB
Flexible PoE options with 60W to 180W power budgets across 8-, 10-,18- and 26-port models
Selectable cloud or standalone management with a user-friendly setup wizard
Compact and near-silent design is ideal for any working environment
Benefits:
Connect everything. Manage anywhere.
Reliable Gigabit connectivity, effortless management and room to grow – the GS1915v2 Series delivers everything a small business network needs. From 8 to 26 ports, there's a Cloud/Smart Managed Switch for every deployment - shop floor, hotel lobby or industrial site.
Silent fanless desktop and wall-mount models suit front-of-house spaces, smart-fan rack-mounts keep cool in the cabinet, and a rugged DIN-rail model with dual AC/DC power redundancy handles harsher environments.
Setup takes minutes – plug in, connect, done. And with Gigabit SFP fibre uplinks on every model, the network is ready to grow with your business.
Everything connected, nothing complicated.
9x Gigabit Cloud/Smart Managed Switches, one simple choice. From 8 to 26 ports, with flexible PoE and Nebula cloud or standalone management, the GS1915v2 Series connects your whole business – no complexity, no compromise.
Designed to disappear into any workspace.
Not every business has a server room – and the GS1915v2 Series doesn't need one. Compact and space-saving, these switches are made to work where your business works: tucked under a counter, mounted behind a till or sitting quietly on a shelf.
Fanless models run in complete silence, while smart-fan cooling (GS1915-18EPv2/26EPv2/26HPv2) keeps larger units whisper-quiet – so there's no background hum in small offices, coffee shops or retail stores where every bit of atmosphere counts.
And with desktop, wall-mount, rack-mount and DIN-rail options across the range, there's a GS1915v2 to fit whatever space you have – even when that space is barely there at all.
More power. More devices. Zero drama.
Six PoE models deliver budgets from 60W to 180W, with up to 30W PoE+ per port for access points, IP cameras and VoIP phones – one cable for data and power.
Continuous PoE keeps critical devices running through switch reboots, while time-based scheduling switches devices off out of hours to save energy.
Need power where there's no socket? The GS1915-8PDv2 draws its power from an upstream PoE switch.
Click. Tap. Done.
Get up and running in minutes with the Nebula mobile app. With just a few simple clicks, our user-friendly step-by-step wizard walks you through the entire installation process, no technical expertise required.
Once connected, the intuitive interface gives you complete control, making it easy to adjust settings, monitor performance and manage your network anytime, anywhere.
