A-2 Troubleshooting
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.
Transmission Mode
Be sure each port on the SwitcHub is set to the same transmission mode as the
attached device; i.e., full-duplex or half-duplex. (Refer to
Setting the Communica-
tion Mode
in Chapter 2 for a detailed description.)
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.
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 in good
working condition.
Configuration
If problems occur after altering the network configuration, restore the original
connections, and 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.
