Power supply

TICRO 100 does not provide an ON/OFF switch! The device automatically powers up after supply
voltage is applied.
There are three possibilities to supply TICRO 100 with power:
1. Power supply via Power over Ethernet (PoE).
2. Power supply via the plug-in power supply unit provided on delivery.
3. Power supply via any suitable external DC supply voltage.
You can supply TICRO 100 using only one of these power supply options or using a combination of
two or all three options to provide power supply redundancy. When supplied by two external power
supplies (options 2. and 3. above), TICRO 100 automatically switches to the other source without any
interruption if one power source fails. If supplied via PoE and an external power supply (option 1. and
2. or option 1. and 3.), TICRO 100 will reboot after switching from the external power supply (option 2.
or 3.) to PoE power supply (option 1.).
NOTICE
Equipment damage possible.
The DC power inputs of TICRO 100 are protected against polarity reversal if only one input is used
at a time.
► When using both DC power inputs, make sure to observe the correct polarity for both inputs.
Reversed polarity on one of the DC power inputs would make the reverse polarity protection
ineffective and could damage TICRO 100.
If powered via the delivered plug-in power supply unit or by an external DC supply voltage,
TICRO 100 is able to operate as a power sourcing equipment (PSE) for class 1 devices
according to IEEE 802.3af.

Power supply via Power over Ethernet

The easiest method for supplying TICRO 100 with power is via Power over Ethernet (PoE) according
to IEEE 802.3af. Power supply via PoE does not require any additional cabling since it uses the same
cable (RJ45 port) for Ethernet communication and power supply.
Power supply via PoE is not possible if you are using an optical fiber Ethernet network.
The Ethernet network port used to supply TICRO 100 (i.e., the network port TICRO 100 is connected
to) must be able to supply a class 3 powered device (power consumption < 13 W).
If no suitable PoE source (e.g., an Ethernet switch) is available, it is also possible to insert a suitable
PoE injector between the Ethernet port on the network side and the Ethernet port of TICRO 100. A
PoE injector is not included in the scope of delivery.
