Hirschmann GREYHOUND-Switch

Gigabit Ethernet switch with extended range of software features, designed for use in harsh industrial environments with a need for cost-effective, entry-level devices. As network needs change, the switches offer flexibility through field exchangeable port modules. They also feature a rugged design to handle demanding industrial applications, including power generation and distribution operations, like substations.

  • Flexibility – the switches are designed with the future in mind through customizable and interchangeable media modules to keep pace with evolving network needs.
  • Designed for industrial environments – built to withstand high temperatures, high vibration and electrostatic discharge often found in industrial automation and power utility settings.
  • Reliability – achieve improved network availability through new management features, including redundancy protocols, diagnostic features and comprehensive security mechanisms

Your Benefits

The GREYHOUND switches offer a unique combination of price, ports and software features – compared to other Ethernet switches on the market. For all-around network protection and uptime, GREYHOUND offers enhanced features through Hirschmann’s operating system, HiOS. The software feature range includes network management, diagnostics and filter functions, as well as comprehensive security mechanisms. Unlike standard products or even configurable products from the factory, GREYHOUND is not limited by design. Network administrators can react to changing needs in their application and adjust the product as many times as needed, all while in the field. The installation is fast, easy and flexible.

Hirschmann™ GREYHOUND

The GREYHOUND Gigabit Ethernet switches are offered in two basic versions. The configuration options include:

  • 16 Fast Ethernet TX ports
  • Eight Fast Ethernet TX ports, plus eight Fast Ethernet small form-factor pluggable (SFP) ports
  • It is also possible to add four Gigabit Ethernet Combo ports

The basic units offer a media module slot that allows customers to add or change ports in the field, as their network design requirements change in the future. The modules can be ordered in versions from all-copper to all-fiber, depending on the individual need.

For applications that face harsh environmental conditions and are under extreme pressure to keep both costs down and customer pricing low, the GREYHOUND switch is an ideal low-entry product. The ruggedized GREYHOUND switches have been specially designed to handle demanding electrical power generation and distribution applications, including new installations and retrofits of existing substations, where ambient temperatures can be extremely high. The de- vices also perform well in transportation and industrial automation applications. For example, with railroad optical networks, passenger and information systems in train stations, conveyor systems, as well as traffic surveillance on highways, bridges and in tunnels.
