Key Applications

PoE can be used to power PoE-capable surveillance cameras, telephones and badge readers, allowing customers to reduce wiring. The ML3000 supports both the 802.1af PoE and 802.1at PoE+ standards, with up to 32 ports PoE or 16 ports PoE+. The ML3100 supports the 802.1at PoE+ standard, with up to 16 ports PoE+.

ML3000 equipped with PoE power supply supported input voltage for PoE or PoE+. Available with a field replaceable power supply in the ML3001 model.
ML3100 equipped with PoE+ power supply supported input voltage for PoE+. Available with a field replaceable power supply in the ML3101 model.
Sales of the ML3100 & ML3101 have been discontinued. As an alternative, please refer to S20 or ML3000 or ML3001.
Maximum Power over ethernet combinations

The MultiLink ML3000 Series supports the end-to-end transparent clock, boundary clock and ordinary clock as specified in the IEEE 1588v2 standard. This allows a timing signal to maintain its accuracy as it passes through an Ethernet network. Customers can reduce wiring costs by relying on their substation LAN to deliver a high accuracy timing signal.

Web Interface

Easy-to-Use Web Configuration and Reporting Software

The EnerVista Web configuration software allows the programming of settings in the MultiLink Ethernet Switches using a simple web browser. Accessible by typing the pre­configured IP address of your switch into the address bar of a web browser, the user-friendly graphical interface allows for easy navigation, monitoring and configuration through simple point-and-click operations.

  • Communication status & port navigation
  • Instant graphical indication of the status of all communication ports
  • Identify the configuration of all communication parameters
  • The ability to click on any of the shown Ethernet terminals to jump immediately to the settings screen for that port
Intuitive Menu Driven Configuration
  • Navigate through configuration screens using an easy to understand categorized menu tree
  • Configure all settings using menu driven pull-down fields
  • Program alarm triggers by selecting from a list of all possible conditions
  • Eliminate the need to memorize any CLI commands
Powerful Troubleshooting Statistics
  • Monitor traffic statistics using intuitive bar graph representations
  • Identify the amount and type of traffic sent and received through each port of the switch
  • Simplify troubleshooting by identifying the number of CRC errors, collisions, and dropped packets occurring on each port
  • Clear and restart the capturing of port statistics to allow for troubleshooting of specific network problems
