β Frequently Asked Questions (FAQ)
π What is the difference between PoE and PoE+ on this managed Zyxel switch?
The GS1920-24HPv2 supports the PoE+ standard (IEEE 802.3at) which delivers up to 30 watts per port, compared to 15.4W for standard PoE (802.3af). This higher power allows powering demanding network devices such as high-resolution motorized PTZ IP cameras, tri-band WiFi 6 access points, IP phones with color touch screens, or PoE digital signage displays. The total budget of 375W allows simultaneous powering of all ports in PoE+.
βοΈ How does Zyxel's NebulaFlex cloud management work without a license?
NebulaFlex is an exclusive Zyxel technology offering total flexibility: switch at any time between free Nebula cloud management (no subscription fees or license) and local standalone mode via the web interface. The Nebula cloud platform allows centralized multi-site administration from a web browser or mobile app, with real-time monitoring, automatic alerts, mass configuration deployment, and analytical reports. Ideal for geographically distributed infrastructures (store chains, bank branches, multi-site establishments). Switching modes is done in a few clicks without resetting or losing configuration.
π‘ Can I connect this network switch to my fiber optic internet box?
Absolutely! The GS1920-24HPv2 connects perfectly to your fiber box (Orange Livebox, Freebox, SFR Box, Bouygues Bbox) via a simple RJ45 CAT5e/CAT6 Ethernet cable. Plug one port of the switch into a free LAN port on your box to distribute the Internet connection to all your wired network devices (computers, NAS servers, printers, IP cameras, WiFi access points). The 4 combo SFP ports also allow direct fiber optic connections if you have a professional fiber termination (FTTO).
π§ Does this smart switch require complex configuration?
No, the switch is plug-and-play for basic use: plug in the power and your Ethernet cables, it works immediately as a standard unmanaged switch. To take advantage of advanced features (VLANs, QoS, LACP link aggregation, security ACL), access the intuitive web interface via a browser by typing the switch's IP address. The user-friendly graphical interface requires no command line knowledge. Guided configuration wizards included. Alternative: use the Nebula mobile app for simplified setup from an iOS or Android smartphone/tablet. Complete documentation and quick guides available.
π‘οΈ Is the switch compatible with VLANs to segment my business network?
Yes, absolutely! The GS1920-24HPv2 fully supports VLANs 802.1Q with the ability to create up to 4096 distinct VLANs for advanced network segmentation. Logically separate your traffic: guest WiFi VLAN isolated from the Internet, office VLAN for employees, VLAN for servers/sensitive data, VLAN for video surveillance, priority VoIP telephony VLAN, IoT/home automation VLAN. VLAN configuration by port (access, trunk, hybrid) with tagging/untagging. GVRP support for automatic VLAN propagation. Enables compliance with security regulations (GDPR, PCI-DSS) and optimization of enterprise network performance.
π How many IP cameras can I power simultaneously with PoE+?
With a total PoE budget of 375W, you can power up to 24 IP cameras simultaneously if each consumes about 15W (standard HD/Full HD fixed cameras), or 12 power-hungry PTZ cameras of 30W each. Practical examples: 24 fixed dome cameras 4MP + remaining network power supplies, 18 motorized bullet cameras 5MP with optical zoom, 15 outdoor PTZ cameras 4K with heating/ventilation, or a mix of devices (20 cameras + 4 WiFi access points PoE). The switch intelligently distributes the available PoE power with automatic detection of needs by device and configurable prioritization.
π‘οΈ Is the gigabit switch noisy with its cooling fans?
The GS1920-24HPv2 features an intelligent variable-speed ventilation system that automatically adjusts the fan rotation according to internal temperature and PoE load. Under normal office use (moderate PoE load of 30-50%), the fans remain quiet (~27 dBA) comparable to the ambient noise of a quiet office. At full PoE load of 375W with all ports active, the ventilation speeds up slightly but remains acceptable in a professional environment. For shared office installations sensitive to noise, prefer rack mounting in a closed cabinet or a dedicated technical room. A silent alternative: Zyxel fanless models (without a fan) for ultra-quiet environments.
π What is the difference between this HPv2 model and the standard v2 model without PoE?
The main difference lies in the PoE power supply: the GS1920-24HPv2 (HP model) provides PoE+ power on its 24 ports with a budget of 375W, allowing network devices (cameras, WiFi, IP phones) to be powered via a single Ethernet cable. The standard GS1920-24v2 model (without HP) has no PoE capability and requires a separate power supply for each connected device. Other differences: higher power consumption for HP (463W max vs 22W), heavier weight (3.8kg vs 2.1kg) due to the internal PoE transformer, increased chassis depth (270mm vs 131mm). Layer 2 network features, NebulaFlex, and SFP ports are identical.
