4 Design Features Design Features The EtheRx hub complies with the full set of repeater basic functions as defined by IEEE 802.3, Section 9. These functions include all Repeater Functions, Signal Regeneration, Jabber Lockup Protection, Fragment Extension, Collision Handling, Auto Partitioning/Reconnection, and Link Test. 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

Design Features 5 Automatic Partitioning/Reconnection If any of the ports on the EtheRx hub experience excessive 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 received without a collision, the hub will automatically reconnect that port to the network. Link Test For UTP port connections, the EtheRx hub implem

The front and rear panels of the Stackable hubs are used for illustration. Note: WorkGroup hubs have identical features except for the Stacking Ports.

Hardware Installation 7 Utilization and Collision LEDs There are five Utilization and five Collision LEDs to display the network traffic and number of collisions on the network. The utilization LEDs measure the amount of data traffic in frames per second (FPS). The LEDs will light in relation to the amount of traffic. The collision LEDs measure the collisions per second (CPS). The LEDs will light in relation to the amount of collisions. FPS/CPS % Activity LED 1 LED 2 LED 3 LED 4 LED 5

8 Hardware Installation 8 or 16 UTP Port LEDs The LINK/ACTIVITY/PARTITION LEDs use two colors to display three states of operation for the 8 or 16 UTP ports. 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. A flash may be longer or shorter depending on the length of the data packet being received. If the port is partitioned

Hardware Installation 9 Using a Straight-Through Cable Using a Crossover Cable Fig. 1-4 Cable Switch functions Notes on MDI and MDI-X Ports MDI (Media Dependent Interface) is the IEEE 10BASE-T standard for the interface to the UTP cable. For two 10BASE-T devices to communicate with each other, the transmitter of one device must be connected to the receiver of the other device. This can be achieved by using a crossover cable, or by using one MDI-X port that implements the cross

Fig. 2-2 KNE16TP/SE Rear Panel BNC Port This port is labeled BNC, and has a built-in transceiver for direct 10BASE2 connection via thin coaxial cable. Use RG-58 A/U or RG-58 C/U type cable. Refer to Appendix B for 10BASE2 cabling guidelines when connecting to this port. AUI Port On 16-Port Models only. The AUI port is a 15-pin D-sub con

Network Configurations 11 Network Configurations The installation of the EtheRx hub is simple and can be configured for either the Ethernet Star topology, Linear Bus topology, or vertically stacked (SE models only), or horizontally cascaded to other Ethernet hubs. For cascading, please observe the Ethernet 5-4-3 Rule. Ethernet 5-4-3 Rule The Ethernet 5-4-3 rule states that the maximum transmission path permitted between any two stations is: • 5 segments • 4 repeater sets • 3 coax

12 Network Configurations Linear Bus Network The typical network configuration for 10BASE2 networks is a Linear Bus topology in which nodes are connected to the BNC connector via a thin coaxial cable. This configuration allows 10BASE2 nodes to communicate with a 10BASE-T segment. A BNC 50Ω (Ohm) terminator must be attached to each end of the trunk segment. One of the terminators must be grounded. The purpose of the terminators is to terminate the network and block electrical interf

Network Configurations 13 Stacking EtheRx SE Hubs The EtheRx SE hubs use stacking ports located on the front panel to stack up to five SE hubs in any combination of 8-Port KNE8TP/SE and the 16-Port KNE16TP/SE models. Follow the directions below to stack up to five SE hubs together: 1. Locate the 5.5” shielded twisted-pair cable included with your package contents. 2. Plug one end of the cable into the port labeled, “Stack Out” on the first hub. 3. Plug the other end of the cable into
