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

The modern factory or data-centre often needs a reliable network core that can grow with the business, yet many managers hit a wall when the existing switch cannot handle extra ports, temperature swings or noisy environments. The Modular managed Industrial Switch solves those pain points. It delivers a fan-less, rack-mountable platform that follows IEEE 802.3 standards and runs HiOS 09.0.11, giving you a sturdy, scalable backbone without the hassle of overheating or frequent upgrades.

Modular managed Industrial Switch - flexible networking for tough environments

Industrial networks demand uptime, flexibility and protection from harsh conditions. When a switch cannot expand, you face bottlenecks, costly downtime and the need for a complete replacement. This switch removes those worries by offering modular port expansion, a rugged fan-less chassis and a wide operating temperature range, ensuring your network stays fast and stable even in extreme settings. It lets you add fibre or copper links as required, while the built-in management tools keep configuration simple and secure.

Usages

A short overview of where this switch shines:

• Connect PLCs and HMIs in a manufacturing line, keeping real-time control traffic reliable.
• Provide uplink capacity for edge servers in a remote oil-field installation where space is limited.
• Serve as the core of a smart-building network, linking CCTV, access control and IoT sensors.
• Extend a campus network with additional fibre runs without needing separate switches.
• Replace legacy equipment in a railway signalling system, benefitting from the fan-less design for low-maintenance operation.

Benefits

• **Scalable port count** - start with 12 fixed ports and grow to 28, so you only buy what you need now and add later.
• **Quiet, fan-less operation** - no moving parts means lower power use and fewer failures in dusty or vibration-prone sites.
• **Wide voltage acceptance** - works with 60-250 VDC or 110-240 VAC, allowing easy integration into existing power schemes.
• **Robust temperature tolerance** - operates from -40 °C to +70 °C, so it survives freezers, warehouses and outdoor cabinets.
• **Easy field replacement** - power supplies are hot-swappable, minimising downtime when maintenance is required.

Key Features

• Fan-less 19-inch rack-mount design keeps the unit silent and reduces maintenance.
• Supports up to 28 ports, including 4 × GE/2.5GE SFP slots and 2 × FE/GE SFP slots for flexible media choices.
• Provides 6 × FE/GE TX ports and additional module slots that add 8 × FE/GE ports per module.
