Troubleshooting
Resetting the Switch to the Factory Default Settings
Autonegotiation and Network Interface Cards
Problems sometimes occur between the switch and third-party network interface cards (NICs). By default, the switch
ports and interfaces autonegotiate. Laptops or other devices are commonly set to autonegotiate, yet sometimes issues
occur.
To troubleshoot autonegotiation problems, try manually setting both sides of the connection. If this does not solve the
problem, there could be a problem with the firmware or software on the NIC. You can resolve this by upgrading the NIC
driver to the latest version.
Cabling Distance
If the port statistics show excessive FCS, late-collision, or alignment errors, verify that the cable distance from the switch
to the connected device meets the recommended guidelines. See
