Disabling the Factory Reset
You can disable the factory reset procedure, even if users depress the Reset / Default switch. Disabling the
factory reset means that users will not be able to revert the Mediatrix 4104 back to its factory settings if there
are configuration problems.

To change the factory reset behaviour:
1. In the sysAdminMIB , set the sysAdminDefaultSettingsEnable variable to disable .
In this case, users can only perform a Recovery Mode procedure. See “Reset / Default Switch” on
page 18 for more details.
Software Restart
You can initiate a software restart of the Mediatrix 4104 by using MIB parameters.

To perform a software restart:
1. In the groupAdminMIB , locate the groupAdminMIBObjects group.
2. Set the groupSetAdmin variable to the appropriate type of restart:
• Locked : waits for the state of all lines to be locked, and then restarts. This is called a
graceful restart.
• ForceLock : restarts immediately. This is called an abrupt restart.
• Unlock : the command is discarded.
3. Set the groupReset variable to SoftReset .
The Mediatrix 4104 restarts.
Restart Behaviour
This feature affects the behaviour of the Mediatrix 4104 when it restarts.
You can instruct the Mediatrix 4104 to check its TCP/IP stack before declaring the restart successful.
This could be useful when the unit is subjected to a broadcast storm (such as a TCP/IP flood) while it is
restarting. In this case, and when the TCP/IP stack check is enabled, the unit enters into the rescue mode and
cannot be contacted through SNMP. You thus need to restart the Mediatrix 4104 manually. However, when
the TCP/IP stack check is disabled, a broadcast storm during a restart will cause the unit to continuously restart
until the storm subsides.

To define the restart behaviour:
1. In the bootBehaviorMIB , enable the checkTcpIpStackForSuccessfulBoot variable.
When the variable is enabled, the TCP/IP stack must initialize properly to consider the restart a
success. In a flood scenario, the unit may end up in the rescue mode.
When the feature is disabled, even if the TCP/IP stack fails to initialize during a TCP/IP flood, the
restart is considered successful and the unit does not enter into the rescue mode.
