Figure 7 shows an example of test results of a single signature PoE device that passes.
Figure 7. PoE Test Pass Example
The hardware class section passes because:
• The device identifies as a HW Class 6 capable of 51.0 W at PD.
• The Product applies a load to the device to validate if the available power from the PSE at the
PD meets the standard of the negotiated class (in this example, a Class 6 device).
• The device delivers 55.0 V under the load which is ≥42.5 V, the minimum amount required for
a device to meet the Class 6 standard.
The software class section passes because:
• The device identifies as a SW Negotiated Class 8 capable of 71.3 W at PD.
• The Product applies a load to the device to validate the available power from the PSE at the
PD meets the standard of the negotiated class (in this example, a Class 8 device).
• The device delivers 54.2 V under the load which is ≥41.1 V, the minimum amount required for
a device to meet the Class 8 standard.
PoE devices fail a test if:
• The device identifies as capable of a negotiated hardware class greater than the power the
device can deliver under the load required to meet the standard for the stated class.
• The device identifies as capable of a negotiated software class greater than the power the
device can deliver under the load required to meet the standard for the stated class.
• The switch under test cannot deliver power to the device because the maximum power which
the switch can deliver is already in use.
