Troubleshooting method

Verify that the correct power source is used and the power cords

are correctly connected.

Verify that the power source side provides power supply correctly.

Verify that the network cable is correctly connected to the network

port of the switch.

Insert the two ends of a network cable into two network ports of the

switch. If the port LEDs are off, replace the network cable.

Ping 127.0.0.1 to verify that TCP/IP has been installed.

Ping the management IP address of the switch to verify that the

management PC is connected to the switch. If not, perform the

following check:

For local configuration, verify that the IP addresses of the

management PC and the switch are in the same subnet.

For remote configuration, verify that the route from the

management PC to the switch is reachable.

Identify the LED status to verify that the cables are connected

correctly.

Verify that the switch's port that connects to the management PC is

enabled and belongs to the management VLAN.

Verify that the Web browser is not configured with proxy or dial-up

connection.

Disable and then enable the local network after you complete local

network settings.
