IMPORTANT: The auto-MDIX feature is always activated on the CloudGate. This feature
automatically detects the required cable connection type (straight or crossed), and
configures the connection appropriately, removing the need for crossover cables.
In order for auto-MDIX to work correctly, auto-negotiation (auto speed and auto
duplex) must be enabled on both sides of the link. Note that auto negotiation is always
active on the CloudGate.
WAN/LAN Switchover Feature
The WAN/LAN switchover feature is a mechanism to maximize the internet connectivity
via the Ethernet port.
The description of the related configuration parameters and the switchover mechanism
itself can be found in the Ethernet Tab section of the CloudGate Setup Guide.

1.8.5. Power Requirements
Base Unit Power Supply
The symbol on the label at the bottom side of the CloudGate shows the power
requirements:
Input voltage must be between 9V - 33V DC
Internal electronic fuse limits the input current to 1.2A
For the power cable between the external power supply unit and the CloudGate
Option recommends to use a power cable that has a wire thickness of 22 AWG!
SAFETY WARNING
This CloudGate operates on DC power provided by a DC power supply or by an AC
power adapter. Only use power supplies in the range 9-33V DC and make sure the
product is installed near a power outlet that is easily accessible.
When using the KNX card, only use a 24Vdc power supply.
SAFETY WARNING
When using an AC adapter make sure that the ambient temperature doesn’t exceed
the specified temperature limits of the AC adapter.
SAFETY WARNING
The CloudGate is regarded a Class III equipment: this means that the protection against
electrical shock is provided by means of power supplied by an SELV (Safety Extra Low
Voltage) circuit and that the CloudGate does not generate hazardous voltages within
itself.
When using an AC power adapter make sure it provides protection against electrical
shock, class II, and that it is certified for the country where it will be used.
As a reference, the power supply available from Option has the following parameters:
Output voltage 12V DC
Max output current 1A
In case you would like to use an industrial power supply Option recommends the next:

SAFETY WARNING
On old CloudGate models, a huge inrush current caused by capacitors inside the
CloudGate may cause an internal fuse to break. When using an external power supply
with an output voltage higher than 15V, Option recommends using a special cable
which will reduce the amplitude of these charge currents. This cable can be obtained
at your CloudGate distributor.
If the fifth digit of the serial number of the CloudGate is a "C", the CloudGate is an older
model and susceptible to this remark. If the fifth digit is not a "C", the fuse of your
CloudGate will not get broken due to these charge currents.

1.8.5.1. Internal Power Circuits
The voltage applied by the power adapter to the CloudGate is converted into different
voltage rails on the main board. Two different power circuits make five different voltage
rails.
Dedicated high current power circuit
Provides two different voltage rails which both can deliver high current levels:
V_PWR: At the power adapter input of the CloudGate there is an
overvoltage protection circuit and a current limiter of 1.2A. The V_PWR is
the voltage level behind the current limiter. The protection circuit causes
a little voltage drop lower than 1V.
3V4: the 3V4 is a power rail generated by a dedicated power circuit on
the main board. The 3V4 is used on the main board and is also available
on the expansion boards.
Low power circuit generated by the micro controller
Provides three voltage rails for very limited power:
3V3: A 3.3V power rail provided by the micro controller is used on the
mainboard and also accessible to the expansion boards
1V8: A 1.8V power rail provided by the micro controller and only used on
the main board
1V2: A 1.2V power rail provided by the micro controller and only used on
the main board
Voltage Rail Voltage Usage Max Current
V_PWR Equals the voltage
applied by the
power adapter,
minus the drop over
the protection circuit
Use for power-hungry
devices
Current is limited to
1.2A
3V4 3.4V Powers all standard

which the main
board is already
using 1.5A. Only 1.5A
is left for both
expansion cards.
(The sum of both
expansion cards
should be lower than
1.5A)
3V3 3.3V Powers low power

and circuitery on the

converter (3V3, 1V8
and 1V2). The
maximum output
current capability of
each output of the
converter is
dependent on the
loads on the other
two outputs.

1.8.6. Reset Button
On the back side of the unit there is a reset button behind the hole in the top panel
(indicated by the "2" in the picture above).
This button allows to restart the unit or to reset it to the factory settings:
press and hold for less than ten seconds to reset the unit to the last working
settings,
press and hold for ten seconds or more to reset the unit to factory settings.
