Disabling the Factory Reset
You can disable the factory reset procedure, even if users depress the Default Settings switch. Disabling the
factory reset means that users will not be able to revert the Mediatrix 1204 back to its factory settings if there
are configuration problems.
X
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 “Default Settings Switch” on
page 19 for more details.
Software Restart
You can initiate a software restart of the Mediatrix 1204 by using MIB parameters.
X
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 1204 restarts.
Restart Behaviour
This feature affects the behaviour of the Mediatrix 1204 when it restarts.
You can instruct the Mediatrix 1204 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 1204 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.
X
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.
In the Unit Manager Network Administration Manual , refer to chapter Performing Actions on Mediatrix Units ,
section Restarting a Unit .
