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