Solution
Check the power cord connections and the connected
device. Ensure 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. Ensure that
all cables used are correct and comply with Ethernet
specifications. Check for a defective computer adapter
card, cable, or port by testing them in an alternate
environment where all products are functioning.
Make sure that the attached device is set to
autonegotiate.
Verify that the cabling is correct. Ensure that all
connectors are securely positioned in the required
ports. It is possible that equipment was accidentally
disconnected.
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 management
interface, you can configure the Spanning Tree
Protocol (STP) to prevent network loops.
