Design Features 5 Design Features The Fast EtheRx 100BASE-TX hubs comply with the full set of repeater functions as defined by IEEE 802.3u, clause 27. These functions include all Repeater Functions, Signal Regeneration, Jabber Lockup Protection, Collision- Handling, Error-Handling, and Auto Partitioning/Reconnection. These functions are usually transparent to all network activities and are summarized below. Repeater Functions If any single port senses the start of a valid packet on i

6 Hardware Installation Automatic Partitioning / Reconnection If any of the ports on the Fast EtheRx Hub experience excessive numbers of consecutive collisions, duration collisions, or faulty conditions, that particular port can be partitioned. Once partitioned, the hub will continue to monitor that port. If the error conditions have been corrected or a good data packet is transmitted without incurring a collision, the hub will automatically reconnect that port to the network. Hardware

Hardware Installation 7 UTP Port LEDs The UTP Port LEDs indicate Link, Activity, Error, and Partition status. If a good link is established on any given port, the green LED will be continuously lit, indicating a valid network connection between the network node and the hub. When data is received, the LED will flash green. If the port is partitioned or encounters an error, such as jabber, false carrier, misalignment, or invalid packet, the LED will flash amber. If an LED does not indicat

10 Hardware Installation • KNE100TX/RSC for SC connectors. Stacking Fast EtheRx Hubs The Fast EtheRx hubs use stacking ports located on the rear panel to stack up to six hubs in any combination of 8-Port, 12-Port, or 24-Port models. Follow the directions below to stack up to six hubs together: 1. Locate the 50-pin shielded stacking cable included with your package contents. 2. Plug one end of the cable into the port labeled, “Out” on the first hub. 3. Plug the other end of the cable
