The SLK-RPR series integrated service access node machine produced by Beijing Slink Computer Communication Equipment Co., Ltd. is a series of industrial grades for strict and demanding operating environments such as real-time communication, network security, wide temperature and humidity working conditions, and high electromagnetic interference. product. This series of products can provide complete network management, switching and security capabilities, and provides system and device power-off alarm functions according to actual engineering needs, which can effectively improve system availability and maintenance timeliness.

The SLK-RPR series of integrated service access node machines can form redundant networks. Each switch can automatically determine the optimal transmission path and alternate path and can implement fast redundant industrial switches. Widely used in industries such as power, transportation, energy and other industrial automation.

Product Features


  • Support redundant ring network protection SLK-RPR (switching time <50ms), MSTP/RSTP/STP (IEEE802.1w/d) redundancy protocol.
  • The flexible networking mode can form a ring network, a chain network, a star network, and a tangent ring network.
  • Supports access layer Gigabit ring network to ensure transmission bandwidth. It provides two Gigabit SFP optical interfaces and two 100M or Gigabit optical interfaces locally, which can effectively solve the last 100m access problem.
  • The port loop protection function effectively prevents ring storms.
  • The use of advanced heat sink cooling technology, unique concave and convex surface, to ensure the maximum thermal diffusion of internal components in the absence of fans.
  • The high standard seal design allows the unit to operate in harsh environments and severe EMI interference.
  • Power input levels are available in flexible configuration options, and DC power supplies provide redundant inputs.
  • A relay alarm output port is available to provide a power failure alarm function.
  • Supports automatic generation of Layer 2 network topology and centralized network management.
