  • Switch traffic between a Gigabit-speed fiber multimode backbone and two copper Gigabit segments.
  • Or use the second copper port to provide access to other Ethernet devices.
  • Supports distances up to 550 meters (1804.4 ft.) on 50-µ fiber or 220 meters (721.8 ft.) on 62.5-µ fiber.
  • Features high-grade components and special thermal design for industrial use.
  • Robust steel case protects circuitry and communications from demands of factory applications.
  • No internal airflow required for cooling. Convection case works as a heat sink.
  • Resists dirt, debris, moisture, smoke, and insects (IEC529 IP40 rated).
  • Designed for NEBS compliance to withstand shock, vibration, and high altitudes.
  • Copper ports autonegotiate to network and device speeds.
  • Autocross (MDI-X) on copper side. Cascade easily without the need for crossover cable.
  • Provides full 10-, 100-, and 1000-Mbps switching for high-performance LANs.
  • Supports VLANs. Retrieves and transmits 802.1q tagged data packets unchanged.
  • Use store-and-forward type switching to eliminate bad packet propagation and maximize bandwidth.
  • Dynamically allocates buffer space, minimizing dropping of frames on congested ports.
  • Collision-based flow control (half-duplex mode only) stops frames from entering when buffer queue space is low.
  • Internal addresses are self-learning. Change port connections or domains without affecting operations.
  • Operates transparent to software.
  • Plug-and-play installation.
  • Includes metal panel mounting clips.
  • RoHS compliant.
  • A combination hardened edge switch and media converter.
  • Enables you to convert copper to optical fiber.
  • Includes two 10-/100-/1000-Mbps copper switch ports and one 1000-Mbps fiber multimode SC port.
  • Converts 1000BASE-T to 1000BASE-SX multimode fiber.
  • Withstands temperatures of -13 to +140º F (-25 to +60º C).
Environmental Operating temperature: -13 to +140° F (-25 to +60° C);
Humidity: 5 to 95% noncondensing
