3. FUNCTIONAL DESCRIPTION
3.2.3 Human-Machine Interfaces
This section describes the human-machine interfaces of the TTE-Switch Lab Space.
3.2.3.1 Power Button
The power button is located right next to the power connector on the rear panel of the switch (see Figure
4 on page 14). To turn on the power, press the power button into the ǀ position.
NOTE
The power button also serves as a disconnect device.
3.2.3.2 Reset Button
The reset button (see Figure 3 on page 13) is recessed and can only be pushed with a thin tool, such as
a pencil. This prevents that the reset button is pushed by accident. A long press of the reset button of
approximately 10 seconds (the Status LED will light up green) will load the default configuration.
3.2.3.3 Status LEDs
In operation, the front panel LEDs (see Figure 3 on page 13) of the TTE-Switch Lab Space indicate the
following status information:
Power Status Sync Error Description
The Power LED lights up green when the power supply of the
switch is turned on.
The firmware is running without active TTEthernet synchroniza-
tion. If the Default mode was selected, then the default configu-
ration is loaded and the Status LED lights up green. If the User
mode was selected, then the user configuration is loaded (see
Table 3 on the facing page) and the Status LED lights up green
only if the user configuration file is valid.
The firmware is running with active TTEthernet synchronization.
If the Default mode was selected, then the default configuration
is loaded. If the User mode was selected, then the user configu-
ration is loaded. The Sync and Status LEDs light up green.
The firmware is running without active TTEthernet synchroniza-
tion. No user configuration is loaded or the uploaded user config-
uration file has an error. The Error LED lights up red.
The debug support unit is active (e.g., during a firmware upload)”
The Power LED lights up red if the PCB registers excess voltage.

3.3 Technical Data
3.3.1 Cooling
The switch is constructed for passive cooling only and can withstand an operational ambient temperature
ranging from 0 °C to +60 °C.
NOTE
When the switch is used in environmental conditions with temperatures exceeding +45 °C, it is mandatory
to mount the switch in a suitable rack to avoid the risk of burns or other personal injury.
