CheetaHub Power-3012A User’s Guide
iv Quick Installation
6. To connect a Fast Ethernet switch, run straight-through twisted-pair cable
from the MDI daisy-chain port on this hub (Port 12) to any MDI-X station
port on the other device (or vice versa). Refer to Figure 3.3. If necessary,
you can also cascade between two station ports using crossover cable.
7. To uplink to the network via a Fast Ethernet switch port, you can install one
of the optional switch modules. The 100BASE-TX module can be uplinked
to Fast Ethernet networks by attaching it to a switch or another repeater hub.
It can also be used to provide dedicated access for a heavily used file server
or a power user. Or you can use a 100BASE-FX module to connect to a
remote site up to 2 kilometers (1.24 miles) away. (Refer to Chapter 2 for a
more detailed description of length restrictions for fiber optic cable.)
The transmission mode is set by auto-negotiation to full or half duplex for
both the 100BASE-TX and 100BASE-FX modules. The speed is set at 10 or
100 Mbps using auto-sensing for the 100BASE-TX module; while the speed
of the 100BASE-FX modules is fixed at 100 Mbps.
8. 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 CheetaHub, refer to Chapter 2 for
a detailed description of installation procedures, Chapter 3 for sample
configurations, or Appendix A for help in troubleshooting.
