HIRSCHMANN GREYHOUND GRS1130-16T9TMMZ9HHSE2S05.0.01 is a rack-mounted managed industrial switch from the Hirschmann Greyhound GRS1130 series under Belden. Designed as aggregation-layer equipment for industrial sites and core communication hardware for power substations, it runs HiOS L2S firmware and features a fanless 1U standard 19-inch rack-mount form factor.
The base configuration includes 16 Fast Ethernet copper ports plus 4 Gigabit combo ports with shared fiber/copper interfaces. One expansion slot for 8-port media modules is reserved, allowing on-site replacement of fiber or copper expansion modules as required.
The unit complies with stringent industrial certifications including IEC61850-3 for power substations and EN50121-4 for rail transit. It operates within a wide temperature range of 0°C to 60°C and is equipped with dual redundant power supplies compatible with industrial AC and DC power inputs. Balancing robust industrial network stability and flexible future expansion via both hardware and software, this switch is suitable for high-reliability communication applications across power, rail transit, factory automation and other industries.
Product Specifications
Hardware Specifications
The unit features a 1U height design for standard 19-inch cabinet mounting, and supports multiple installation modes including flat placement and vertical wall mounting. It adopts a fanless aluminum alloy enclosure with passive heat dissipation, with a maximum power consumption of 10.5W. All ports support auto-speed negotiation: 10/100 Mbps copper ports and 10/100/1000 Mbps combo shared ports. The expansion slot is compatible with GMM series 8-port media modules, with optional 8-copper-port modules and 8-single/multi-mode SFP fiber modules. Dual independent power terminals support mixed 110–250 VDC and 100–240 VAC power supply. Each port is equipped with an LED link status indicator, alongside unit-wide operation alarm LEDs for intuitive visual fault identification. A hardware-isolated management console port enables local debugging without occupying service ports.

Product Advantages
- Modular expandable design with an integrated media module slot. Copper and fiber ports can be added or removed without powering down the device, meeting phased capacity expansion and renovation requirements for projects and cutting subsequent hardware replacement costs.
- Industrial-grade electromagnetic protection and vibration-resistant structure with high immunity to electrostatic discharge and surges, suitable for factory and substation environments with heavy dust and strong electromagnetic interference.
- Dedicated compliance certifications for the power industry, fully compliant with communication standards for smart substations and power distribution automation, and ready for direct connection to relay protection and measurement & control device networks.
- The HiOS operating system embeds a full suite of industrial redundancy protocols. MRP and HRP ring networks achieve millisecond-level self-healing switching to rapidly restore data transmission after link failures.
- Multiple management access channels are available for operation and maintenance, including web GUI, SSH, local serial console, USB debugging, and the Industrial HiVision management software.
- Dual independent power inputs operate as mutual redundant backups. Communication services remain uninterrupted upon loss of one power feed, eliminating single points of power supply failure.
- Fanless passive cooling design with no wearable rotating components, drastically reducing long-term maintenance and inspection frequency, ideal for unattended equipment rooms.
- Unified software platform with continuous firmware iteration. It supports industrial-IT convergence functions including Modbus TCP, OPC UA, ACL access control, and port mirroring.
