Align and tighten the captive retaining screw at each end of the module front panel (see Connecting Cables to TokenSpeed Ports...

  • Page 34: Token Ring Connections

    Token Ring Connections When you connect a network device to a token ring port on the TokenSpeed module, you must specify a TokenSpeed port type using SpeedView. The port type setting is based on the type of network connection you are connecting to the TokenSpeed module.

  • Page 35: Verifying The Installation

    A serial connection for a SpeedView network management station is provided on the TokenSpeed/MCP module. The cable for this connection is shipped with the Centillion switch. Attach the serial MCP cable to the Mini DIN 8 port on the TokenSpeed/MCP module (see Figure 3-7.

  • Page 39: Removing And Replacing A Module

    Installing a TokenSpeed/MCP module resets the switch and loads the default configuration, thus interrupting network connectivity. If you are adding a module to an empty slot in an already functioning switch, follow the instructions that begin on module, follow the instructions in the next two sections.

    For instructions on saving configuration files, refer to Using SpeedView 2.1 for Windows. If you have an extra Centillion switch chassis, you can minimize network disruption by loading the saved configuration on the new TokenSpeed/MCP module using the additional chassis; then replace the old module.

For module configuration instructions and for instructions on saving and downloading files, refer to Using SpeedView 2.1 for Windows.

  • Page 42: Replacing A Tokenspeed Module

    Replacing a TokenSpeed Module You do not need to turn off the switch power before you replace a TokenSpeed module that does not have an MCP. To replace a TokenSpeed module, follow these steps: Disable all ports on the module using SpeedView, or disconnect the cables from each port.
  • Page 43 Rotate the left and right inserter/extractor levers away from the center of the module to loosen the module from the backplane connectors (see Figure 3-11).

  • Page 48: Port Insertion Problems

    Port Insertion Problems Symptom: The Act LED on a token ring port does not flash for a period of 15 to 20 seconds. No flashing on the Act LED on a token ring port typically indicates port insertion problems. To resolve the problem, follow these steps: Verify that the port is not operational by accessing the SpeedView multicast frame transmit and receive count statistics (Mcst xmit and Mcst rcv).
  • Page 49 If Speed Sense is enabled, be sure that at least one device on the connected ring is not set to Speed Sense. If the switch is connected to an intelligent hub that has automatic speed sensing, such as a Bay Networks hub, configure a specific speed for the port on the TokenSpeed module and disable the Speed Sense option.
