Verify Cable Connections
Check to see that the computer(s) you are troubleshooting are properly connected.
Each computer must be connected from its DFE-528TX with Category 5 UTP
cables. Examine the Network cables and ensure that they have not been damaged by
walking-on, rolling over with chairs, or closed in doors. Additionally, make note of
and alleviate any possible electromagnetic interference that may be affecting your
network.
Your network cables can be plugged into any port on your hub except the "Uplink"
port. The "Uplink" port is only used when connecting your hub to another hub or
switch.
Understanding Indicators
Your DFE-528TX has indicators or lights that can give you information about your
network traffic and help you determine problems when troubleshooting.
Your DFE-528TX’s have two indicators labeled "ACT" and "LINK" on their back
panels. A steady green "LINK" light indicates a good connection with the Hub. A
flashing green "ACT" light indicates that the Network Adapter is sending or
receiving data.
Diagnostics and Checking Communications
Included on the CD labeled "DFE-528TX PCI Ethernet Adapter Driver Program" is
a diagnostic program that will help you determine if any faults exist in your DFE-
528TX Network Adapters or connections.
1. Restart your computer in MS-DOS mode. (Click "Start", then "Shut Down... "
and finally select "Restart the computer in MS-DOS mode?")
2. Insert the CD labeled "DFE-528TX PCI Ethernet Adapter Driver Program" into
your CD-ROM drive (D:).
3. Type D:\DIAG at the MS-DOS prompt, (where “D” is your CD-ROM drive)
