Product recommendation | Supports Broadcast Storm Suppression — Solidot D Series Unmanaged Switch

As the number of devices in an industrial network increases, the source of broadcast frames becomes uncontrollable. When a node abnormally keeps sending broadcast frames, the broadcast traffic may occupy the entire bandwidth of the network segment, causing communication interruption for other devices — this is a broadcast storm. The solution lies not at the configuration level, but at the hardware level.

The Solidot D Series Unmanaged industrial Ethernet switch is designed for exactly this purpose, covering all combinations of Fast Ethernet and Gigabit Ethernet, 5 to 16 ports, and pure Ethernet ports or SFP Fiber Ports. Building on Plug and Play, it implements Broadcast Storm Suppression via a DIP switch.

Key parameters at a glance

If there are more than 10 devices on site, or the network has broadcast traffic from uncertain sources, the D Series' Broadcast Storm Suppression and enhanced EMC protection provide a more solid safety baseline.

I. How to choose between Fast Ethernet and Gigabit Ethernet (5-port/8-port)?

The Fast Ethernet models (SW4-HUP05D, SW4-HUP08D) cover the communication needs of common industrial control devices such as PLCs, frequency inverters and HMIs. The Gigabit models (SW4-GUP05D, SW4-GUP08D) are aimed at scenarios requiring higher backplane bandwidth, such as vision systems, large-scale data acquisition or upstream aggregation. The main differences between the two are as follows:

II. How to choose between 16-port and SFP Fiber Port models?

The 16-port models (SW4-HUP16D, SW4-GUP16D) feature a standalone housing, suitable for scenarios with centralized access for multiple devices. Both models have a built-in Relay Alarm Output: one NO + one NC, with a contact rating of 1 A @ DC 24 V, which can be used to connect external audible/visual alarms or for host computer monitoring. The main parameters are as follows:

The SFP models (SW4-GUP04D-SFP2, SW4-GUP08D-SFP2) add SFP Fiber Ports on top of Gigabit Ethernet Ports, enabling long-distance fiber optic transmission. The main parameters are as follows:
