Build a 40-user network anywhere—or add up

to 40 users to your existing network.

Key Features

Stack five units to support up to 40 users.

Includes eight shielded RJ-45 connectors and one AUI connector. Optional BNC or fiberoptic connectors available.

Offers full 10BASE-T functionality with an exceptionally small footprint.

LEDs show basic network activity.

Durable steel enclosure and compact size.

The Stackable MiniHub is a compact, unmanaged hub

offering low-cost connectivity for IEEE 802.3/Ethernet 10BASE-T networks. Each hub has eight shielded modular jack ports and one AUI port. A BNC or Fiber port is optional in addition to the AUI.

Up to five hubs can be stacked to form a single logical repeater with 40 modular jack ports and four AUI, BNC, or Fiber ports. This feature allows you to build larger networks without violating IEEE 802.3 guidelines.

Port 8, on the front of the MiniHub, has an uplink switch for internal crossing over of the 10BASE-T port. This allows you to

connect to other hubs without using a crossover cable.

It may be tiny, but the Stackable MiniHub has everything you expect in a 10BASE-T hub. Featuring full repeater functionality, the MiniHub also offers jabber protection to prevent lockup from excessively long packets, automatic partitioning and reconnection of ports experiencing excessive collisions, and automatic polarity detection that compensates for wiring errors on the receive pair.

To aid operation, troubleshooting, and diagnostics, the MiniHub has 20 front-panel LEDs that display hub status and link activity.

Typical Applications include:

•Networking a personal multi-system office using 10BASE-T twisted-pair cabling

•Temporary network for trade shows

•Lab or office environments that need an independent Ethernet network

•Expanding small independent networks

•Testing your network—use the MiniHub as a test port
