Daisy-Chain IN Port When cascading a set of D-Link’s stackable dual-speed hubs, this port should be connected to the Daisy-Chain OUT port of the previous hub in the stack (usually placed immediately above it). A cascade of five hubs can be created in this way.

  • Page 31: Module Indicators (Slot1 & 2)

    Module Indicators (SLOT1 & 2) The two module indicators, SLOT1 and SLOT2, indicate a good link to a module installed in the respective slot. For the DFE-260S switch module the indicator will come on when the module is installed. For the DFE- 260FX and DFE-260TX modules, the slot link indicator should light when- ever the module is installed and there is a valid link.

  • Page 32: Port State Indicators

    Dual-Speed Stackable Hubs User’s Guide Port State Indicators There is one port state indicator for each of the twisted-pair ports on the hub.

    SNMP Indicator (Master models only.) This indicator comes on when the SNMP agent of a DFE-2600 series mas- ter hub is active. In a stack with both a Primary and a Backup Master, the SNMP LED of the Primary master will be lit and will flash to indicate SNMP activity.
  • Page 34 This indicator lights continuously under the following two conditions: 1. A good connection has been established with a console (for example, a PC or other computer). The diagnostic port of a DFE-2600 series master hub must be connected to the console's RS-232 serial port using a normal serial cable.

    AKING ONNECTIONS This chapter discusses how to make connections to the hub’s twisted-pair and console ports, cascading hubs to create a stack, and linking with other hubs (or hub stacks). Hub Cascading/Building a Stack You can stack up to five hubs using the daisy-chain ports to form one logi- cal hub.

    The maximum length of a twisted-pair segment (that is, the distance between a port in the hub to a single-address network device such as a PC, server, or Ethernet switch) is 100 meters. Cabling and other wiring should be certified as Category 5 UTP or shielded twisted- pair(STP).

  • Page 38: The Diagnostic Port

    DCE-to-DTE connection requires a straight serial cable, not a null-modem cable. You can use the diagnostic port on a DFE-2600 series master hub to con- nect a VT100-compatible terminal or a computer running an ordinary terminal emulation program (such as the terminal program included with the Windows operating system).

A console device can only manage a DFE-2600 series hub if it is cas- caded to a DFE-2600 series master hub. Use either the on-board console program or an SNMP-based network management program to manage the stack.
  • Page 40 Dual-Speed Stackable Hubs User’s Guide connections require either a Category 5 UTP cable or an STP cable. These cables can be up to 100 meters long. Each Ethernet connection requires a Category 3 or better UTP cable. It is recommended that you use Category 5 cabling for all connections, in order to make it easier to transition all stations to 100Mbps.

  • Page 41: Hub-To-Hub Uplink

    Hub-to-Hub Uplink You can link two hubs or hub stacks to each other using any of the twisted- pair ports or the Uplink port. Linking hubs using ordinary twisted-pair ports requires crossover twisted-pair cables; linking using one ordinary twisted-pair port and the Uplink port requires an ordinary straight-through twisted-pair cable.

    Optional Module Connections There are three optional modules that may be added to any of the DFE- 2600 series hubs. Each hub can accommodate two modules. Each of the modules offers a different additional network interface that allows for greater flexibility in how these hubs may be used in a network. The sections that follow provide a brief overview of the module and basic instructions on any settings and indicators.

    The Fiber Optic module provides a standard Fast Ethernet 100BASE-FX fiber optic connector. A fiber optic connection of this kind is particularly useful for creating a link between two DFE-2600 series hub stacks, placing them in separate collision domains. A link of this sort eliminates the need for an external switch to divide stacks into separate domains.

    The Fast Ethernet module provides one additional twisted-pair Fast Ethernet connection. A twisted-pair connection of this kind is particularly useful for creating a link between two DFE-2600 series hub stacks, placing them in separate collision domains.

  • Page 53: Segmenting Hubs

    Segmenting Hubs Switching hub technology has made it more common to segment local area networks into smaller pieces to reduce congestion. Segmenting makes it easier to balance network loads, since a smaller number compete for the bandwidth available. A hub stack makes network management convenient, but too many stations on a single network segment may give slow response at peak network loads.
  • Page 54 Hubs three and four are isolated from the main segment (collision domain one) using the hub's segmentation capability, putting them into their own isolated collision domains two and three respectively. A switch, bridge or router can be used to connect the three collision domains so that traffic can pass between them, yet keeping them isolated to reduce conges- tion on each segment.

  • Page 55: Logging In To The Hub Console

    Logging in to the Hub Console The DFE-2600 series master hubs support user-based security that allows you to prevent unauthorized users from accessing the hub or changing its settings. This means that before you can access the functions of the hub, you will need to first log into the hub, providing a password.
