Zyxel GS1915-18v2 - 16-Port Smart Managed Switch
16 x 10/100/1000 Mbps2 x Gigabit SFPNo PoE output or inputStandalone GUI or NebulaFlex
The Zyxel GS1915-18v2 is a fanless Smart Managed Layer 2 switch for wired networks that need 16 Gigabit RJ45 ports and two Gigabit SFP uplink slots. It supports standalone web management or NebulaFlex cloud management. This exact model has no PoE output or PoE-powered input.
Best For: For small offices and other wired networks needing 16 Gigabit Ethernet ports, two SFP uplink options and configurable Layer 2 management. It is not suitable where the switch must power PoE devices directly.
Before you order: This is the non-PoE GS1915-18v2, not the GS1915-18EPv2. Its two uplinks are Gigabit SFP, not SFP+ or 10Gbps, and SFP modules and fibre cabling are separate. Cloud management requires an account/registration, internet and suitable configuration; some advanced Nebula features may require an extra licence. Confirm the regional mains plug, and provide an AC outlet, network uplink and suitable cables. Keep it indoors with ventilation and suitable mounting support.

- Power cord
- Wall-mount kit
- Rack-mount kit
What It Means in Practice
- Use the 16 RJ45 ports for 10/100/1000 Mbps Ethernet connections; the two SFP slots provide Gigabit uplink options, with compatible transceivers and matching cabling purchased separately.
- Choose the standalone web GUI for local management or NebulaFlex cloud management. Cloud use requires an account/registration, internet and suitable configuration; ordinary local switching does not require a cloud subscription.
- LACP or static aggregation supports up to 8 groups and 8 links for this model, but requires matching peer configuration and does not guarantee multiplied throughput for a single traffic flow.
- The switch draws power from AC mains. Since it has no PoE output or PoE-powered input, connected PoE devices require their own power or separate suitable PoE equipment.
What Will Not Work
- No PoE output or PoE-powered input; it cannot power access points, phones or cameras over Ethernet.
- The two uplink slots are Gigabit SFP, not SFP+ 10Gbps or 2.5GbE. Compatible transceivers and matching opposite-end fibre/optics are needed for fibre use and are not included.
- Cloud management needs a Nebula account/registration, internet and suitable configuration; some advanced features may require an extra licence. Confirm any required paid feature licences separately.
- Requires an AC outlet, network uplink and suitable Ethernet cables. The regional mains plug has not been verified.
- For indoor ventilated installation; no DIN-rail or outdoor weatherproof use is established. Provide ventilation/clearance and suitable mounting support.
Key Features
16 Gigabit Ethernet ports
Connect up to 16 wired devices over 10/100/1000 Mbps RJ45 ports.
Two Gigabit SFP uplinks

Frequently Asked Questions
Does this switch provide PoE?
No. The GS1915-18v2 has no PoE output and no PoE-powered input. Connected access points, phones or cameras need their own power or separate suitable PoE equipment.
What are the 18 ports?
There are 16 RJ45 Ethernet ports supporting 10/100/1000 Mbps and two Gigabit SFP uplink slots. The SFP slots are not SFP+ 10Gbps ports.
Are SFP modules and fibre cables included?
No. SFP transceivers and fibre cables are separate purchases; choose compatible optics and matching opposite-end fibre/optics.
Can I manage it without Nebula cloud?
Yes. The switch supports a standalone web GUI. Cloud management requires a Nebula account/registration, internet and suitable configuration; some advanced features may need an extra licence.
Singular Expert Insight
Its 16 RJ45 ports and two Gigabit SFP slots provide a clearly defined mix of copper connections and optional fibre uplinks, with a choice of local web or NebulaFlex cloud management. The exact GS1915-18v2 is non-PoE, so PoE devices need their own power or separate PoE equipment.
Buyer’s Guide
✓ Buy it if For small offices and other wired networks needing 16 Gigabit Ethernet ports, two SFP uplink options and configurable Layer 2 management. It is not suitable where the switch must power PoE devices directly.
✕ Skip it if This is the non-PoE GS1915-18v2, not the GS1915-18EPv2. Its two uplinks are Gigabit SFP, not SFP+ or 10Gbps, and SFP modules and fibre cabling are separate. Cloud management requires an account/registration, internet and suitable configuration; some advanced Nebula features may require an extra licence. Confirm the regional mains plug, and provide an AC outlet, network uplink and suitable cables. Keep it indoors with ventilation and suitable mounting support.
→ Also consider If connected devices need power over Ethernet, choose a confirmed PoE switch configuration instead; the GS1915-18v2 cannot provide PoE. If you plan to use its SFP slots, budget for compatible transceivers and matching fibre or other cabling separately.
