Page 6 - Introduction

1. Introduction Introduction This hub is an Ethernet Hub designed for the 10Base-T environment.In terms of topology, twisted-pair Ethernet 10Base-T is defined as astar topology rather than a bus. Each port on the hub connects to onlyone 10Base-T device via unshielded twisted-pair (UTP) cable. The hu...

Connecting to an Ethernet Node To connect the hub to a 10Base-T Ethernet node, follow these steps: 1. Select an appropriate length of 10Base-T UTP cable for the connection. 2. Connect one end of the UTP cable to the MDI jack on the remote device (e.g., a PC equipped with 10Base-T Ethernetadapter). 3...

4. Interpreting Hub LEDs Locations of the Hub LED Indicators The hub provides the following LEDs : • One Power status LED• One Collision status LED• Eight Link and activity status LEDs. One for each TP port Interpretations Power LED The LED indicates the status of the hub's power source. Match theac...

Page 14 - Collision LED

Collision LED This LED indicates the collision detected by the hub. The LED isnormally off and it blinks when there are collisions. As the frequencyof collisions on a network increases, the blink activities (on-time) ofthe LED also increase. Link/Rx LED Each TP port has one Link/Rx LED to indicate t...
