A-2 Troubleshooting
Use the diagnostic procedures described in Chapter 2 and the
following section to verify that all other system components are
functioning properly. If you still cannot resolve the problem,
contact your Accton distributor for assistance.
System Diagnostics
Installation
Verify that all system components have been properly installed.
If one or more components appear to be malfunctioning, test
them in an alternate environment where you are sure that all the
other components are functioning properly.
Cabling
1. Verify that the cabling type is correct. Be sure all cable
connectors are securely seated in the required ports.
Straight-through cable should be used for all standard
twisted-pair connections; and multimode cable with SC or
ST type connectors should be used for fiber optic
connections.
2. Make sure all devices are connected to the network.
Equipment may have been unintentionally disconnected from
the network.
External Adapters
Make sure the network adapter cards installed in the
workstations are compatible with your network media type and
are in good working condition.
Configuration
If problems occur after altering the network configuration,
restore the original connections, then try to track the problem
down by implementing the new changes, one step at a time.
Ensure that cable distances and other physical aspects of the
installation do not exceed recommendations.
