6.2.1 Partial Reset
You can perform a partial reset of the EX Controller to:
• Reset the password of the EX Controller Web GUI. For example, if you have forgotten
the password.
• Contact the unit in a known state when you can no longer access the EX Controller
Web GUI. For example, due to modified configuration. In such case, you can manage
the EX Controller using the Rescue Network Interface. The Rescue Network Interface
is bound to the WAN port ETH1 of the unit and accessible through the IP address
192.168.0.1. (IPv4) or an IPv6 Link Local address.
The Rescue Network Interface is used for:
• Completing the configuration of a new unit.
• Modifying existing configuration.
By default, the Rescue Network Interface is disabled. When a partial reset is
performed, the Rescue Network Interface becomes enabled and the Power and
Ready LEDs are blinking at 1Hz with 75% duty and all other LEDs are off. Once the
configuration has been modified to solve the problem that required the partial reset,
