Hirschmann GRS1042-6T6ZTHH12VYHHSE3AMR, 28 Ports L3 Managed Industrial Switch

When you are trying to keep a factory floor or a remote site online, a single network failure can bring production to a halt and cost you thousands. You need a switch that can survive harsh environments, stay cool without fans and give you full control over every port. The Modular Managed Industrial Switch 19-inch Rackmount - HiOS Release 8.7 is built for exactly that - a reliable, fan-less solution that follows IEEE 802.3 standards and lets you manage traffic with confidence.

Modular Managed Industrial Switch 19-inch Rackmount - HiOS Release 8.7

This switch solves the problem of unreliable connectivity in industrial settings where dust, temperature swings and limited space are everyday challenges. Without a robust switch, you risk frequent downtime, difficult troubleshooting and costly maintenance visits. The modular design lets you add or replace port modules as your network grows, while the fan-less chassis eliminates moving parts that can fail. Together with a powerful HiOS management interface, you get a clear, stable network backbone that keeps your operations running smoothly.

Benefits

• Zero-noise operation - the fan-less design removes acoustic distractions and reduces mechanical failure points.
• Scalable port capacity - start with 12 fixed ports and expand to 28 total ports using interchangeable modules.
• Rugged temperature tolerance - operates from -40 °C to +70 °C, ideal for outdoor or factory environments.
• Flexible power options - dual field-replaceable power supplies accept 60-250 VDC or 110-240 VAC, ensuring uptime even if one source fails.
• Comprehensive management - HiOS 09.0.11 provides advanced monitoring, VLANs and QoS, giving you full control over traffic flow.

Usages

The switch is perfect for connecting PLCs, HMI panels, CCTV cameras and edge servers in manufacturing plants, oil-and-gas sites or transportation hubs. Use the built-in SFP slots for fibre links between buildings, while the copper ports handle local device connections. The optional auto-configuration adapters (SD-card ACA31 or USB ACA22-USB) make rapid deployment simple, and the RJ45 V.24 console port gives you direct access for troubleshooting. Whether you are building a new smart-factory network or upgrading an existing one, this switch adapts to the layout you need.
