Power
PoE capable models will attempt to power any valid PoE Powered Device (PD) that is connected to a copper port.
The PoE PD must meet the requirements for IEEE 802.3af and/or IEEE 802.3at for it to negotiate properly. Devices
with invalid PD signatures or non-PoE devices will not be powered ON.
PoE capable models will remove power from the Powered Device if any of the following conditions occur:
•
Minimum power requirements are not satisfied. The PD must draw minimum required current set forth by
802.3af/at specifications in order to be powered on.
•
Maximum power is exceeded. The PD must not exceed the power levels set by the 802.3af/at specification.
•
The PoE device signature becomes corrupted.
•
The maximum power budget is exceeded.
