FAQ

  • The cable is connected, but the port will not come UP / the link is down. What should I check?

    +

    1) Confirm an industrial-grade cable and proper RJ45 crimping. 2) Check speed/duplex settings; set both ends to auto-negotiation. 3) Check whether the port is administratively shut down, in the wrong VLAN, or restricted by port security.

  • What are the PoE power specifications?

    +

    Standard PoE and PoE+ are supported, with max per-port power of 15.4 W and 30 W respectively. Total system power budget must be calculated during selection to avoid insufficient supply when too many PDs are connected.

  • Which ring protocols are supported, and what is the self-healing time?

    +

    Mainstream industrial ring protocols such as ERPS (G.8032), RSTP/STP, MRP, and PRP are supported. ERPS typical self-healing is ≤50 ms; traditional RSTP is second-level. It is recommended to use one ring protocol consistently across the network.

  • How should I choose between Layer-2 and Layer-3 industrial switches?

    +

    Layer-2 switches: basic features such as VLAN, ring networks, and port mirroring; suited to access layers and same-subnet networking with strong cost performance. Layer-3 switches: add static routing, OSPF, DHCP relay, multicast, and other routing features—choose these when cross-subnet communication or core/aggregation networks are required.

  • Can non-OEM SFP optical modules work normally?

    +

    The device is compatible with generic IEEE 802.3 SFP modules. Non-OEM modules can usually be recognized, but some brands may have compatibility issues. OEM modules are recommended.

  • How do I restore factory settings if I forget the device login password?

    +

    1) Hardware reset: press and hold the RESET button for 5–10 seconds; the device reboots to factory defaults. 2) Software reset: use the vendor NMS to restore factory settings remotely. All custom configurations will be cleared after restore.

  • What are the power supply requirements for industrial switches?

    +

    DC models support 18–60 VDC or 9.6–60 VDC; AC models support 100–240 VAC, with dual redundant power inputs. Phoenix terminal wiring; reverse-polarity protection is built in so normal reverse connection will not damage the device.

  • What are the operating temperature range and protection rating of industrial switches?

    +

    All-metal aluminum alloy housing. Operating temperature is -40°C to +75°C; premium wide-temperature models reach -40°C to +85°C. Typical enclosure rating is IP40.
