1. Connect one end of an RJ-45 Ethernet cable (cable type: straight through) into the WAN port of the
UCM6510; connect the other end into the uplink port of an Ethernet switch/hub.
2. Connect the 12V DC power adapter into one of the power jacks located on the back of the UCM6510.
It is highly recommended to connect the other end of the plug to a surge protected power outlet. For
power redundancy, connect a second 12V DC power adapter into the other power jack.
3. Wait for the UCM6510 to boot up. The LCD in the front will show its hardware information when the
bootup process is done.
4. Once the UCM6510 is successfully connected to the network, the LED indicator for the WAN port in
the front will be solid green, and the LCD will display the IP address.
Note: The ground screw needs to be connected.
