Introduction

The PowerTrans PT-508 Series is designed to meet the demands of power substation automation systems (IEC 61850-3, IEEE 1613). The PT-508’s optical fiber Fast Ethernet backbone, redundant ring, redundant power inputs (24 VDC or 48 VDC), and isolated power inputs (24 VDC, 48 VDC, or 110/220 VDC/VAC) increase the reliability of your communications and save on cabling/wiring costs. In addition, the DIN-rail and wall-mounting design of the PT-508 switches simplify network planning, and allows greater flexibility by letting you install up to 8 Fast Ethernet ports for power distribution applications.

Additional Features and Benefits

  • Command line interface (CLI) for quickly configuring major managed functions

  • VLAN Unaware: Supports priority-tagged frames to be received by specific IEDs

  • EtherNet/IP and Modbus TCP industrial Ethernet protocols supported

  • Configurable by web browser, Telnet/Serial console, CLI, Windows utility, and ABC-01 automatic backup configurator

  • DHCP Option 82 for IP address assignment with different policies

  • IGMP snooping and GMRP for filtering multicast traffic from industrial Ethernet protocols

  • IEEE 802.3ad, LACP for optimum bandwidth utilization

  • Bandwidth management to prevent unpredictable network status

  • Multi-port mirroring for online debugging

  • Automatic warning by exception through email and relay output

  • RMON for proactive and efficient network monitoring

  • Automatic recovery of connected device’s IP addresses

  • Line-swap fast recovery

Cybersecurity Features

  • User passwords with multiple levels of security protect against unauthorized configuration

  • SSH/HTTPS is used to encrypt passwords and data

  • Lock switch ports with 802.1X port-based network access control so that only authorized clients can access the port

  • RADIUS/TACACS+ allows you to manage passwords from a central location

  • 802.1Q VLAN allows you to logically partition traffic transmitted between selected switch ports

  • Secure switch ports so that only specific devices and/or MAC addresses can access the ports

  • Disable one or more ports to block network traffic

  • SNMPv3 provides encrypted authentication and access security

  • 10/100BaseT(X) Ports (RJ45 connector)

    Note: When connecting a single-mode fiber transceiver, we recommend using an attenuator to prevent damage caused by excessive optical power.
    Note: Compute the “typical distance” of a specific fiber transceiver as follows: Link budget (dB) > dispersion penalty (dB) + total link loss (dB).
