Hello and welcome to Rugged Science ...


IGS-9844GPF(X) 16-port Managed Ethernet Switch

You are here

  • Supports O-Ring (recovery time < 30ms over 250 units of connection)and MSTP(RSTP/STP compatible) for Ethernet Redundancy
  • Open-Ring supports multi-vendor ring technology in open architecture
  • O-Chain for multiple redundant network rings
  • Supports standard IEC 62439-2 MRP (Media Redundancy Protocol) functions
  • Supports IEEE 1588v2 clock synchronization

The IGS-9844GPF(X) is a managed redundant ring Ethernet switch with eight 10/100/1000Base-T(X) ports, four 100/1000Base-X SFP ports, and four 100Base-FX (IGS-9844GPFX series) or four 1000Base-X (IGS-9844GPF series) optical fiber port with SC connector. Complete with support of Ethernet Redundancy protocol, O-Ring (recovery time < 30ms over 250 units of connection) and MSTP (RSTP/STP compatible) protect mission-critical applications from network interruptions and temporary malfunctions with fast recovery technology. This ethernet switch is prepared for any environment by its wide operating temperature range(from -40ºC to 70ºC). The IGS-9844GPF(X) can be managed, centralized, and made convenient by Open-Vision, Telnet, and console (CLI) configuration. This switch is the complete package for highly-managed and Fiber Ethernet applications.
