2-Port Hub, Type 3 Unshielded

Need more workstations? No more MAU ports available? Use our 2-Port Hub!


Please call 877-877-2269 for a replacement product or part.
1 Year Double Diamond™ Warranty (Standard)

Product Features

  • Use inexpensive UTP cable.
  • Connect two workstations to one lobe.
  • No extra MAU port needed.


  • Hot-swappable. No downtime.
  • Nonpowered.

    Add two Token Ring workstations even if an extra MAU port is unavailable. This hub makes Token Ring expansion fast and easy!

    Use a 2-Port Hub to double a single lobe’s capacity, and you can add or remove workstations from the network without any downtime. This means you can operate your LAN without the extra MAU—or extra expense—of a backup ring.

    Just use a patch cable to connect the 2-Port Hub's ring port to your existing Token Ring outlet. Then connect two workstations to Ports 1 and 2 of the hub. You don't even need to plug it into a power outlet because it's a passive, nonpowered device.

    The 2-Port Hub supports Type 3 Token Ring and has unshielded RJ-45 connections for Type 3 unshielded twisted-pair cable, or shielded RJ-45 connections for Type 3 shielded twisted-pair cable.
