RESETTING AND RECOVERING
There may be rare occasions when the main switch or a module needs to be given a hard reset. The DDX switch
and DDX-USR module both have concealed reset buttons for this purpose. You need to use a narrow implement
(e.g. a straightened-out paper clip) to press-and-hold the recessed reset button on the front panel:
DDX switch >
Boot into recovery image
This procedure may be necessary if an attempted firmware upgrade has failed. The
switch will load the factory default configuration, requiring you to log-in using the factory
default username/ password and a freshly determined IP address (see
Accessing DDX
Matrix
). You will be required to accept a new temporary SSL certificate when accessing
the web interface.
Note: All configuration data (e.g. users, consoles, computers, networking, etc.)
will be retained.
1 Press-and-hold the recessed reset button for
ten seconds
until the
STS
(Status)
indicator begins to flash slowly.
2 Release the reset button. The
STS
indicator will go out and the switch will boot itself
using the recovery image. The
STS
indicator will now begin to flash again to indicate
that it is running from the recovery image (a red banner will also be shown at the top
of the DDX Matrix screen).

When you are sure of operating conditions, such as having good power stability,
proceed once again with the firmware upgrade.
DDX switch >
Reset
This procedure may be necessary if the switch has become unresponsive.
Note: All
configuration data (e.g. users, consoles, computers, networking, etc.) will be retained.
1 Press-and-release the recessed reset button. The switch will reboot.
DDX switch
DDX-USR module
DDX-USR module >
Boot into recovery mode
This procedure may be necessary if an attempted firmware upgrade has failed. For such
a situation the DDX-USR module always retains a
recovery image
that will return the unit
to a working condition, prior to reattempting a firmware upgrade.
1 Press-and-hold the recessed reset button for
ten seconds
until the
PWR
indicator
begins to flash quickly.
2 Release the reset button.
3
When you are sure of operating conditions, such as having good power stability,
proceed once again with the firmware upgrade.
DDX-USR module >
Reset
This procedure may be necessary if a DDX-USR has become unresponsive.
1 Press-and-release the recessed reset button. The DDX-USR module will reboot.
Recovering an unresponsive transmitter or receiver
If a firmware upgrade to a transmitter or receiver has failed, the unit may become
unresponsive. If so, please follow the advice provided in other sections of this guide:
