Solution
• Check the power cable
connections at the switch and the
power source.
• Ensure that all cables are used
correctly and comply with the
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.
• Ensure that all cables are used
correctly and comply with the
Ethernet specifications.
• Check for a defective port, cable,
or module by testing them in an
alternate environment where all
products are functioning.
Break the loop by ensuring that only
one path exists from any networked
device to any other networked
device. After you connect to the
switch web management interface,
you can configure the Spanning Tree
Protocol (STP) to prevent network
loops.
