Remove the KVM top cover, locate to J15 that marked "Default Password", apply a jumper cap, power on the unit.  You will see "Restore default username and password" now.  Wait for about 60-90 seconds and "Username and Password information has been erased, please power down this machine and remove the jumper, then restart" can be seen.  Please power off the machine and remove the jumper cap, then boot up the unit.  At the login prompt, the default username/password is "administrator/password".
