Dear all, Looks like I messed up the switch.. - upgrade to latest firmware (1.4.7to 1.4.10) - reboot ok - changed default Vlan 1 to 22 - saved and reboot (this is the culprit i guess) - nothing goes.. ports do not work. (LED flashes but IP 192.168.1.254 does not work) So. reboot, reset, the whole stuff. IP still does not work - console does not work. Tried some cabels, Putty, etc - no response What else can I do? Thanks for any help!

You can process a hard reset on the following way:

 

  1. hold the reset button for 30 seconds and disconnect the power cord from the unit
  2. continue holding while the power cord is a disconnect for another 30 seconds
  3. finally, connect the power cord and hold for the last 30 seconds

In total, you will hold the reset button for 90 seconds, allow between 5 to 10 minutes for the unit to boot up and connect a computer to the switch. Remember to set a static IP in your computer in the same subnet as the default IP of the switch.

 

If after this you are still unable to access or you don't have any activity on the Ethernet or Console port please contact tech support for an RMA.
