2.5 Applying Power

The switch provides two types of power interfaces, terminal block and DC power jack for receiving DC
power input from external power supply.
Using Terminal Blocks
Either DC1 interface or DC2 interface can be used to receive DC power from an external power
system. Or, DC2 also can be used to deliver the power received on DC1 to next switch in cascading
way.
DC1 + Vdc Positive (+) terminal
DC1 - Vdc Negative (-) terminal
DC2 + Vdc Positive (+) terminal
DC2 - Vdc Negative (-) terminal
* Working Vdc for general application: +6.5V ~ +54VDC
* Working Vdc for PoE application:
Three 2P terminal plugs are provided together with the switch. Two of the three plugs are used for DC1
and DC2 interfaces respectively. The plug is shown below:
Install the power source wires with the plug properly. Then, plug in DC1 contacts. If cascading the
power to next switch device is needed, install the power wires and plug for another switch. Then, use
DC2 contacts.
Note: Only up to four device units can be cascaded to receive power from
one main power input source.
+44V ~ +54VDC (Typ. 48V)
Power wires : 24 ~ 12AWG (IEC 0.5~2.5mm
