Page 7: Introduction
DHD-801/1601 User’s Guide NTRODUCTION This chapter introduces your hub and gives some background information about the technology of the hub uses. Product Description DHD-801/1601 is designed to allow easy integration and migration between 10Mbps Ethernet and 100Mbps Fast Ethernet. The hub can operate with both IEEE 802.3 10BASE-T connections and IEEE 802.3u 100BASE-TX connections. -
Page 8: Product Features
SOHOConnect Series expand the network still further. The uplink connection will carry both 10Mbps and 100Mbps network signals. Product Features The list below highlights your hub’s features and specifications: ♦ Compatible with the IEEE 802.3 10BASE-T Ethernet and 802.3u 100BASE-TX Fast Ethernet industry standards for interoperability with other Ethernet and Fast Ethernet network devices. -

Page 14: Port State Indicators
SOHOConnect Series ♦ 10M Collision (COL 10M, DHD-1601) This indicator indicates data collisions on the respective 10Mbps Ethernet segments of the hub. (If several hubs are linked together, all of them should detect and indicate the same collision, since collisions span the entire network segment.) Whenever a collision is detected, the respective 10 COL indicator will briefly... -
Page 15: Making Connections
DHD-801/1601 User’s Guide AKING ONNECTIONS This chapter discusses how to connect end nodes, and uplink two hubs together. Connectivity Rules Ethernet (10Mbps) networks have the following connectivity rules: ♦ The maximum length of a twisted-pair cable segment is 100 meters. Cabling should be Category 3 or better. -
Page 16: Hub-To-End-Node Connections
SOHOConnect Series ♦ If there has a path between any two end-stations, containing five segments and four repeaters, then at least two of the cable segments must be point-to- point link segments (e.g., 10BASE-T or 10BASE-FL). While the remaining segments may be populated segments (that is, they can be 10BASE-2 or 10BASE- 5 segments with end nodes attached). - Page 17 DHD-801/1601 User’s Guide cabling for all connections in order to make it easier to transit all stations to 100Mbps. You can connect any combination of end-station computers, servers, and other addressable network devices to the twisted-pair ports using straight-through twisted-pair cables.

Page 18: Uplink Connection
SOHOConnect Series Uplink Connection You can “Uplink” two hubs to each other using either (a) any two numbered jacks or (b) a numbered jack and an Uplink jack. (In the discussion that follows, the word hub should be taken to mean a hub, in the same product family as your Dual speed Hub.) Uplinking hubs using numbered jacks requires a crossover twisted-pair cable;... - Page 19 DHD-801/1601 User’s Guide HUB PORT DEVICE PORT TYPE CABLE TO USE that is going to attached USED Non-Uplink Crossover (X) Switch or Uplink Straight-through (||) Normal Network end node Straight-through (||) Non-Uplink Straight-through (||) Switch or Uplink Uplink Crossover (X) Network end node Crossover (X) A crossover cable is a twisted-pair cable in which the wires...

Page 22: Crossover Cables
SOHOConnect Series Crossover Cables When making an uplink connection between one hub and another (or between a hub and a switch or bridge) using X- type jacks at both ends, you must use a crossover cable. In a crossover cable, two pairs of wires are switched at one end. -
