For All Mediatrix Units

v. 43.0.1125


1 Partial Reset

The partial reset provides a way to contact the Mediatrix unit in a known and static state while keeping most of the configuration unchanged.

A partial reset can be performed at the initial start-up of the Mediatrix unit or on a unit already in use where the configuration was modified in such a way that the user can no longer access the system by the Web page or otherwise. In both cases, the user will access the Rescue Interface with the Rescue Network Interface using either a static IPv4 address (192.168.0.1 ) or an IPv6 Link Local address connection. These connections give access to the Rescue Management Interface where the configuration of a new unit can be completed and where an existing configuration can be modified.

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, it is important to disable the Rescue Network Interface to make sure that you are no longer working in the Rescue Network Interface.

Performing a partial reset on a new unit will not modify the configuration, as it has not yet been modified to your needs. However, a partial reset performed on a unit already in use will:

  • Rollback Local Firewall settings that are not yet applied.
  • Add a Local Firewall rule to allow complete access to the Rescue interface.
  • Rollback NAT settings that are not yet applied.
  • Add NAT rule to allow complete access to the Rescue interface.
  • Cancel the changes that were being modified but not yet applied to the configuration.
  • Disable any Network Interface in conflict with the Network Rescue Interface.
  • Configure and enable the Rescue Network Interface to:
    • use the link as the default value used by the Uplink Network Interface
    • set the IP address to 192.168.0.1 and the Network Mask to 255.255.255.0.
    • set the IPv6 link-local address on all network links. The IPv6 link-local address can be found underneath the unit.

A partial reset will also modify the following parameters:

Service Parameter Default Value
AAA Users.Password User(s) from profile are restored with their factory password. All other usernames keep their password.
Users.AccessRights User(s) from profile are restored with their factory rights.
ServicesAaaType (table) Each service will be configured to use Local authentication and no accounting mechanism.

1.1 Performing a Partial Reset

Before You Start

Note

It is not recommended to access the unit on a regular basis through the Rescue Network Interface.

Steps

  1. When the Power LED is steady or blinking rapidly, insert a small unbent paper clip into the hole of the Reset/Default button located at the front of the unit.

    Note

    The Power LED will start blinking.

  2. Wait a few seconds.
  3. When all LEDs are blinking, but before they stop blinking, remove the paper clip.

    Note

    You have between 7 to 11 seconds.

Result

The Rescue Network Interface is displayed when accessing the Management Interface. Several parameters and services are modified, refer to Partial Reset. Do not forget to perform the Disabling the Rescue Interface step.


1.2 Disabling the Rescue Interface

Context

By default the Rescue interface is disabled. However, after a partial reset the rescue interface is enabled.

Steps

  1. Go to Management/Misc.
  2. From the Network Interface drop-down menu, select the interface that will be used to manage the unit.

    Important

    If you keep the Rescue Interface selected, you will not be able to get into the management interface after disabling it.

  3. Go to Network/Interfaces.
  4. In the Rescue Interface table, from the Activation selection list, select Disable.
  5. Click Apply.

Result

The unit will be reachable either on the new configured static IP address or on the DHCP .
