iv Quick Installation
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
/LPLWIRU)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.
