Troubleshooting
System Diagnostics
Installation
Verify that all system components have been properly installed. If one or more components are
malfunctioning, test them in an alternate environment where all other components are functioning
properly.
Cabling
Verify that the cabling is correct. Refer to Appendix C, “Cabling Specifications.” Be sure all cable
connectors are securely positioned in the required ports. Straight-through cables should be used for all
standard twisted-pair connections.
Make sure all devices are connected to the network. Equipment may have been accidentally
disconnected.
Network Adapter Cards
Make sure the network adapter cards/network interface cards installed in the workstations are in
working condition. Be sure the AUI media transceiver is functioning properly and that the signal
quality error test has been disabled.
Configuration
If problems occur after altering the network configuration, restore the original connections and
determine the problem by implementing the new changes, one procedure at a time. Ensure that cable
distances, repeater limits, and other physical aspects of the installation do not exceed the
recommendations.
Switch Integrity
If required, verify the integrity of the switch by resetting the switch. Turn off the power to the switch
and then turn the power to the switch back on. If the problem continues and you have completed all
the preceding diagnoses, contact your NETGEAR distributor.
