Hi ,
Best way is reset it factory defaults and reconfigure it.
Here below a step-by-step procedure to reset the switch and reconfigure it back.
To reset the switch to the factory default, please complete the following steps:
1. Unplug the power cord from the switch.
2. While plugging back in the power to the switch, hold setup button.
3. Wait until all LED indicator lights turn amber and release the setup button.
4. When a switch port LED blinks green, connect your PC to that port. This computer must
be configured to get the IP address via DHCP.
5. Open up a web browser. If the browser does not pull up the GUI automatically, then go
to
http://10.0.0.01 and select 'Erase system
configuration and Boot with the factory default IOS image' and click on Submit button.
6. At this moment, the switch is set back to factory default configuration; proceed with
initial setup procedure again.
The basic procedure to setup a CE500 is:
1. Make sure that nothing is connected to the switch.
2. Power up the switch.
3. Wait for the SETUP LED to blink green.
4. Press the setup button. When you press the SETUP button, a switch port LED begins
blinking green.
5. When a switch port LED blinks green, connect your PC to that port. This computer must be configured to get the IP address via DHCP.
6. When the SETUP LED turns green, start a browser session on the PC.
7. Open a web browser. If the browser does not pull up the GUI automatically, then go to
http://10.0.0.1 and configure the device.
8. Enter the network settings, username and password and click Submit.
9. Select the option "No, Thanks" when the switch shows the Recommended Smartport
Assignments windows. You can customize the Smartport role assignment later on.
10. Click Submit to save changes and finish basic configuration.
11. Click Restart/Reset on the GUI dashboard.
12. When the switch comes up, open a browser and go to http://
address>. Please remember to set up you LAN adapter with an IP address within the same
subnet of the switch management interface.
Hope it helps you.Check the status of lights.
Thanks,
