Troubleshooting
Solution
• Check the power cord connections for the
switch at the switch and the connected device.
• Make sure that all cables used are correct and
comply with Ethernet specifications.
• Check the crimp on the connectors and make
sure that the plug is properly inserted and
locked into the port at both the switch and the
connecting device.
• Make sure that all cables used are correct and
comply with Ethernet specifications.
• Check for a defective adapter card, cable, or
port by testing it in an alternate environment
where all products are functioning.
• Make sure that the attached device is set to
auto negotiate.
• Check the system message log
Verify that the cabling is correct. Be sure that all
connectors are securely positioned in the
required ports. Equipment have been
accidentally disconnected.
Break the loop by ensuring that there is only one
path from any networked device to any other
networked device.
