¾ PoE Ports (1-4): These ports support PoE function which
integrates power and data onto one Ethernet cable. Once
the device you connect to the Switch is identified, the Switch
will supply power through the PoE port, and then you can
use it as a 10/100/1000Mbps Auto-Negotiation RJ45
Ethernet port. The working status can be indicated by the
corresponding LEDs on the front panel.
¾ Ethernet Ports (1-8): Besides the 4 PoE ports, the
TL-SG1008P Switch is also equipped with the other four
10/100/1000Mbps Auto-Negotiation RJ45 ports without PoE
function. Once the network devices are connected to these
8 ports through the network cable, the Switch will make
them plug and play according to the Auto-MDI/MDIX
detection. The working status can be indicated by the
corresponding LEDs on the front panel.
Note
Make sure the PDs you connected to the Switch are compliant
with IEEE802.3af.
