Note:
As the factory setting for the DEV 1953, each module slot is forming a single
group for simultaneous switching. This means, that there are sixteen groups
with a single member each initially and that there is no functional difference
between Individual switching mode and Simultaneous switching mode.
To utilize the advantages of simultaneous switching, the group assignment is to
be altered via Web Interface (in Local Mode and with Individual switching mode
activated, please refer to chapter 5.5.7.3.3).
If the switch modules being member of a group are in different positions, it is
not possible to activate Simultaneous switching mode. In this case, the device
panel channel LEDs of all groups with members that are not in the same
position will toggle twice when operating in Local Mode the switching mode
push button. To resolve this situation the same switching position has to be
established by switching the related (i.e. the Simultaneous switching mode
preventing) switch modules in Individual switching mode before activating
Simultaneous switching mode.
Naturally, the Simultaneous switching mode is not available if the device is
equipped with a single switch module, only.
5.2
Initialization of the Device
The device performs a health check and a configuration check during power-up and
after a device reset. This takes about 60 seconds; there is no manual configuration
necessary, all settings (including the operation mode) after power-up or after a
device reset remain unchanged.
Note:
If not a single switch (or distribution amplifier) module is installed, the device
signalizes this by a permanent event indication (i.e. the channel LEDs at the
device panel are blinking and this cannot be stopped).
5.3
Operation via the Device Panel
The local operation (via push buttons) and the status indication (via LEDs) of the
device panel were already explained in chapter 3.1.1.
Note:
The factory default for the operation mode is Remote Mode.
To operate the push buttons at the device panel, the DEV 1953 has to be
switched to Local Mode via the mode push button at the device panel (please
refer to chapter 3.1.1), via Web Interface (chapter 5.5.2), or via SNMP
(chapter 5.9.4.3.1).
