• Verify that you have not exceeded the specified limits for any
attached media type as summarized in the following table:
Media Type Maximum Length (meters)
Twisted Pair 100
Fiber Opitc 412 (at half duplex)
2000 (at full duplex)
Table 2.5 Maximum Cable Length
• If a computer is attached to the hub, verify that its adapter
card is functioning properly by trying it in another computer
that has been successfully connected to the network.
• When using the 100BASE-TX or 100BASE-FX
SmartExtender Module, both sides of each connection must
use the same transmission mode (i.e., full or half duplex). If
the device connected to the hub operates at full duplex but
does not support auto-negotiation, then you must manually set
the transmission mode with the configure button. (Refer to
section on Communication Mode earlier in this chapter.)
If you still can’t resolve the problem, please refer to
Troubleshooting in Appendix A.
