CAUTION:
If you do not use the PoE feature, verify that the PoE power switch on the power supply is off.
Requirements
Power over Ethernet (PoE) enables a power sourcing equipment (PSE) to supply power to powered
devices (PDs) through power interfaces (PIs) over twisted pair cables. Commonly used PDs include
IP telephones, APs, and web cameras.
The following PoE types are available:
•
Type
1
—Power delivered by a single port: 0 to 15.4 W; voltage range: 44 V to 57 V; maximum
current: 350 mA. This PoE type provides power to classes 0 to 3 PDs.
•
Type
2
—Power delivered by a single port: 0 to 30 W, voltage range: 50 V to 57 V, maximum
current: 600 mA. This PoE type provides power to classes 0 to 4 PDs.
To set up a PoE system, the following components are required:
•
A switch that supports PoE.
•
PSEs.
•
An external PoE power supply.
•
PoE power supplies.
A switch that supports PoE
The 7502, 7503, 7503-S, 7506, 7506-V, or 7510 switch.
