Mediatrix 4100
Reset / Default Switch
The Reset / Default switch allows you to:
 Cancel an action that was started.
 Revert to known factory settings if the Mediatrix 4100 refuses to work properly for any reason
or the connection to the network is lost.
 Reconfigure a unit.
At Run-Time
The Reset / Default switch can be used at run-time – you can press the switch while the Mediatrix 4100 is
running without powering the unit off. Table 10 describes the actions you can perform in this case.
At Start-Time
The Reset / Default switch can be used at start-time – you power the unit off, and then depress the Reset /
Default switch and power the unit back on. In this case, the following explains the reset behaviour:
 Pressing the Reset / Default switch at startup until all the LEDs start blinking restarts the
Mediatrix 4100 in “Recovery Mode”. Note that this can take up to 40 seconds.
 Pressing the Reset / Default switch at startup until all the LEDs stop blinking and remain ON
applies the “Factory Reset” procedure. This feature reverts the Mediatrix 4100 back to its
default factory settings.
See “LED Indicators” on page 14 for a detailed description of the LED patterns related to the Reset / Default
switch.
Recovery Mode
The recovery mode restarts the Mediatrix 4100 in a known, static, and minimal state. It is used to recover from
a basic configuration error that prevents you to reach the unit through the network. It may serve as a last resort
before the Factory reset command. You must perform it in a closed network and on only one Mediatrix 4100
at a time, because the default IP address is the same on every unit.
