Fast EtherHub-12se User’s Guide

If your twisted-pair connections are less than 100 meters long, then the length of the fiber optic cable can be extended. Refer the section 'LVWDQFH /LPLW￿IRU￿)DVW￿(WKHUQHW￿&DEOLQJ in Chapter 2 for a description of how to calculate

the maximum length of fiber optic cable that can be used in your particular environment.

6.You can make a cascaded connection to another hub by running straight- through twisted-pair cable from the daisy-chain port 12 (MDI) on this hub to any station port (MDI-X) on the another hub (or vice versa). If necessary, you can also cascade between two station ports using crossover cable. Port 1 can also used to make a fiber optic connection to another compatible hub. Assuming that the maximum cable length is used for end-node connections, then the inter-hub cabling should be limited to 5 meters. However, if you need to extend this length of inter-hub cabling beyond 5 meters, then first

calculate the maximum length permitted between each pair of end nodes as described under the %LW￿%XGJHW section in Chapter 2 (page 2-4).

7.Verify network communications by ensuring that -

∙you have made all the necessary connections

∙you can access any connected resources

∙the hub’s indicators are functioning properly

If you encounter any problems in installing the Fast EtherHub, refer to Chapter 2 for a detailed description of installation procedures, Chapter 3 for sample configurations, or Appendix A for help in troubleshooting.

Note: Refer to Chapter 2 for a more detailed description of calculating the maximum cable length permitted between two end nodes for Fast Ethernet.
