28G-port Layer 3 full Gigabit managed Ethernet switches
Process automation and transportation automation applications combine data, voice, and video, and consequently require high performance and high reliability. The RT-MX7028 series full Gigabit backbone switches are equipped with 28 Gigabit Ethernet ports. They provide Layer 3 routing functionality to facilitate the deployment of applications across networks and make them ideal for large scale industrial networks.

The RT-MX7028’s full Gigabit capability increases bandwidth to provide high performance and quickly transfer large amounts of video, voice, and data across a network. The switches support the RingOn and RSTP/STP redundancy protocols, and are fanless and come with an isolated redundant power supply to increase system reliability and the availability of your network backbone.

  • Layer-3 Switching, Supports Static Routing and RIP V1/V2
  • RingOn and RSTP/STP for network redundancy
  • IGMP Snooping for filtering multicast traffic from industrial Ethernet protocols
  • QoS (IEEE802.1p/1Q) and TOS/DiffServ to increase determinism
  • 802.3ad and LACP for optimum bandwidth utilization
  • SNMPv1/v2c/v3 for network management of different levels
  • Automatic warning by exception through email and relay output
