Connect PoE+ Ports via TP Copper Cable
The Switch also provides 10/100/1000Base-T.
Supported cabling: PoE per IEEE 802.3af PoE supports Cat 3 and Cat 5. PoE per IEEE
802.3at PoE+ supports Cat 5. See
PoE/PoE+ information.
1. Prepare a twisted-pair copper cable.
2. Connect one end of the cable to the Switch.
3. Connect the other end of the cable to a PD, such as a WAP or IP camera.
Note: After the cable is properly connected at both ends, the Switch SYS LED should be
functional. See
LED Descriptions
PoE / PoE+ Spec Comparison
PoE Plus (PoE+) provides extended support for new end devices with higher power requirements. The IEEE
802.3at standard provides up to 30W of power to include newer end devices such as IEEE 802.11n wireless access
points, security surveillance cameras, etc.
