Network Adapter Cards
Verify that the cabling is correct (refer to Cabling Guidelines”). 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.
Make sure the network adapter cards installed in the PCs are in working condition and the software driver has been installed.
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. Make sure that cable distances, repeater limits, and other physical aspects of the installation do not exceed the Ethernet limitations.
