Core Advantages
- Flexible port expansion: Equipped with six 2.5G/Gigabit SFP fiber ports and 24 Gigabit copper ports for hybrid fiber-copper deployment. It accommodates long-distance fiber transmission and local terminal access, enabling integrated backbone aggregation and field access networking with a single unit.
- Redundant dual 110–240 VAC power supply with two independent IEC power connectors. Each power supply has a maximum power consumption of 35 W. Seamless switchover occurs upon power failure to prevent total network outage caused by single power source loss.
- Fanless sealed enclosure with IP30 protection rating, delivering stable operation across a wide temperature range of -10°C to +60°C. It meets industrial mechanical stability standards for vibration and shock resistance. The absence of cooling components eliminates wear and tear, cutting long-term maintenance costs.
- Comprehensive industrial redundant link suite supporting multiple ring redundancy mechanisms including HIPER-Ring, MRP, RSTP, MSTP and LACP link aggregation. Its fast fault self-recovery meets real-time communication requirements of automated production lines.
- Multi-layer security architecture featuring 802.1X port authentication, multi-dimensional ACL access control, DHCP Snooping, Dynamic ARP Inspection, secure boot and firmware signature verification, which blocks unauthorized access and cyberattacks targeting industrial networks.
- Compatibility with multi-protocol industrial buses. Natively supports mainstream industrial Ethernet protocols including PROFINET, EtherNet/IP and Modbus TCP, allowing direct connection to automation hardware such as PLCs, industrial PCs and field instruments.
- Diversified local maintenance interfaces: SD card slot, USB-C debug port and 2-pin alarm signal terminals support offline configuration backup, on-site rapid troubleshooting and visual/audio fault alarm output.
- High-precision time synchronization: Compatible with PTPv2 transparent/boundary clock, 802.1AS and SNTP client/server, satisfying high-accuracy timing control scenarios for smart manufacturing and rail transit.
FAQ
Q1: Can this switch build ring network and link aggregation simultaneously?
A1: Yes. The device supports MRP over Link Aggregation and HIPER-Ring over LACP. Redundant ring networks can be deployed on aggregated links to improve reliability of backbone connections.
Q2: What is the maximum power consumption of the unit when running on a single power supply? Will it exceed the power load of cabinet power supply?
A2: The maximum power consumption with one power supply is 35 W, equivalent to a heat output of 120 BTU/h. It can be easily supported by standard industrial cabinet power loads. Dual power input enables power redundancy.
Q3: Does the switch support mixed networking of 2.5G fiber ports and Gigabit copper ports?
A3: Yes. The six SFP slots accept hot-swappable 1G/2.5G transceivers, while the 24 TX copper ports auto-negotiate 100M/1G speeds. There is no speed isolation between ports for flexible mixed networking.
Q4: Can the switch operate stably in chemical high-temperature workshops at -5°C to 58°C?
A4: The rated operating temperature range of the unit is -10°C to +60°C, so the target temperature falls within specifications. Its fanless design avoids heat dissipation blockage caused by dust, making it suitable for dusty, high-temperature chemical sites.
Q5: Do SD cards and optical transceivers need to be purchased separately at the time of order?
A5: The factory package only includes the main unit and safety documentation. ACA31 adapter, all types of SFP transceivers and management software must be ordered separately.
Q6: How to realize batch configuration backup and rapid equipment replacement?
A6: Use the ACA31 SD card adapter to store standardized XML configuration files. When replacing a faulty unit, simply insert the SD card and power on the new switch; it will automatically load all network parameters without repeated commissioning.
Q7: Which industrial real-time fieldbuses are supported? Is connection to Siemens PROFINET PLC available?
A7: PROFINET, EtherNet/IP and Modbus TCP are embedded natively. Direct connection to full ranges of Siemens and Rockwell industrial PLCs is supported without additional protocol conversion modules.
Q8: If ports drop connections frequently, can the built-in diagnostic functions locate cable faults?
A8: Integrated copper cable test, link fluctuation detection and duplex mismatch detection allow one-click troubleshooting of cable breaks, signal attenuation and poor RJ45 contact issues. Port mirroring is also available to capture traffic for auxiliary analysis.
