  1. Tyler Jenkins –

    Upgraded my network setup with this Dahua switch and it works flawlessly. The 18 ethernet ports and 2 SFP ports give me plenty of room to expand. Web management is very straightforward to use. Quick shipping from apsardze24.lv made the whole experience great. Definitely recommend it!

    Tyler Jenkins –

Does the DH-SG4020 support link aggregation (LACP) for higher speeds?

Yes, it supports both manual aggregation and Static LACP (Link Aggregation Control Protocol). This allows you to combine multiple ports to increase bandwidth and provide redundancy for critical connections.

Is this the official EU version of the Dahua switch?

Yes, this is the **Official EU version** of the DH-SG4020. It is fully compatible with European standards, supports English firmware updates, and faces no region-locking issues. Apsardze24.lv is an Authorized Partner ensuring you get genuine equipment.

What if the switch stops working after the first year?

We provide a comprehensive **2-Year Warranty** for both business and private clients. Since our service center is located locally in **Riga**, any warranty repairs or diagnostics are handled quickly without shipping the unit abroad.

Where can I get technical assistance if I cannot configure the VLANs?

The web interface includes a help section, but for specific configuration challenges with the DH-SG4020, please contact our technical support team directly at [email protected].

Can I install the DH-SG4020 in a standard server rack?

Yes, the switch is designed with a standard 1U rackmount form factor (440mm width). It fits perfectly into standard network cabinets and server racks, keeping your setup organized.

How do I access the management settings for the DH-SG4020?

This switch features a user-friendly Web Management interface. You can access it via a standard web browser (like Chrome or Firefox) on your computer by entering the switch's default IP address, allowing you to configure VLANs, LACP, and other settings without a dedicated mobile app.

Does the DH-SG4020 support PoE (Power over Ethernet) for my cameras?

No, this model is a standard Gigabit managed switch designed for high-speed data transmission. It does not provide PoE power. If you are connecting IP cameras, you will need to power them separately or use PoE injectors.

What are the SFP ports used for on this 20-port switch?

The device includes 2 SFP ports (in addition to 18 Gigabit RJ45 ports). These are used for high-speed fiber optic uplinks, allowing you to connect switches over long distances (beyond the 100m limit of copper cables) or to aggregate data to a core server.

Is this switch suitable for a network with high data traffic?
