The DS Agile H38 is a PRP-compliant Ethernet switch with optical ports supporting 100Base-Fx fiber connections for redundant, high-reliability networking.

Overview

The DS Agile H38 is a standalone Ethernet switch designed for industrial and critical network applications. It is compliant with IEC 62439-3 Clause-4 Parallel Redundancy Protocol (PRP), enabling seamless redundant communication between devices without network downtime . The switch also supports Precision Time Protocol (PTP) IEEE 1588 v2 for accurate time synchronization, which can be output via IRIG-B or NTP .

Optical Port Features

• Fiber Support: The H38 switch provides PRP connections via fiber-optic ports, supporting both multi-mode (short distance) and single-mode (long distance) fibers .
• Port Type: Optical ports use LC connectors and support 100Base-Fx speeds .
• Redundancy: Optical ports are used for inter-switch connections to maintain high availability and reduce interference issues common with copper Ethernet links .

Copper Ports

• The switch also includes three RJ45 copper ports supporting 10/100Base-Tx, with automatic detection of speed (10/100 Mbps) and duplex mode (half/full), .

Configuration and Management

• The H38 can be configured via TELNET using a terminal emulator on a PC .
• Commands allow control of PRP ports, including turning ports on/off and disabling transceivers .
• The switch supports real-time clock synchronization and generates a one-pulse-per-second (PPS) signal for precise timing .

Mounting and Physical Design

• DIN-rail mounting with a metal enclosure suitable for industrial environments .
• Designed for robust operation with redundant power supply options and secure grounding requirements .

Applications

The H38 switch is ideal for industrial automation, power grid communication, and other mission-critical networks where redundancy, precise timing, and optical connectivity are required . In summary, the DS Agile H38 combines PRP redundancy, optical fiber support, and precise time synchronization, making it a reliable choice for high-availability Ethernet networks with optical port requirements.
