Connecting Network Cable
The Switch supports 8 10/100M Ethernet ports with ports 1 through 4
supporting PoE. These PoE ports will automatically activate when a
compatible terminal is connected, and the Switch will supply power
through the Ethernet port to the connected PoE powered device (PD).
For the Legacy devices that are not compatible with PoE, the PoE port
will not supply power to the port. This feature allows users to freely
and safely mix legacy and PoE compatible devices on their network.
The Switch supports 10Mbps Ethernet and 100Mbps Fast Ethernet
and it runs both in half and full duplex mode using two pair of
Category 5 cable.
These RJ-45 ports are Auto-MDI type port. The Switch can auto
transform to am MDI-II or MDI-X type, so you do not have to worry
about whether you are using a standard or crossover RJ-45 cable.
