D-Link DFE-538TX [47/64] Diagnostics and checking communications

Verify Cable Connections

Check to see that the computer(s) you are troubleshooting are properly connected.

Each computer must be connected from its DFE-538TX 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-538TX has indicators or lights that can give you information about your

network traffic and help you determine problems when troubleshooting.

Your DFE-538TX’s have two indicators labeled "ACT" and "LINK" on their back

panels. A steady green "LINK" light indicates a good connection with the switch. A

flashing green "ACT" light indicates that the Network Adapter is sending or

receiving data.
