Method 1
– Connect to the console port of the switch (Speed: 9600 baud, Data Bits: 8, Parity: None,Stop Bits: 1, Flow Control: XON/XOFF). I’ve used Putty.
– Reboot the switch disconnecting the cable power
– Press when the first line is displayed
– Select option i to factory default the switch.

You can reset to factory config using console command
– Enter to activate a session at the end of boot process
– in console submit the next commands

# enable
# restore factory-default

– At the end confirm
– Switch will reboot

Att.: In the boot process on factory default the device will get a DHCP ip address.
Att.: At the end you can get access to web interface, and configure the switch to enable remote console access via SSH or telnet.

Upgrade firmware
You can get new firmware using linkografica.

Att: Pay attention to the switch hardware version. To get this info (and others) you can use the next command using terminal.
