PoE PRO
Understanding the Results
Volts
Voltage displayed on the results screen is the
“loaded” voltage. It is the voltage measured
when the PoE PRO applies a load to the
cable, simulating a PoE device (PD).
This voltage may be lower than the unloaded
voltage displayed when initially connected.
Watts
Maximum available power is displayed in
watts (
W ). This is the most power the PoE
PRO is able to demand from the PoE supply
during the test.
Type (af / at / bt /-)
Displays the IEEE 802.3 standard to which
the connected PSE is compatible.
af = IEEE 802.3af
at = IEEE 802.3at
bt = IEEE 802.3bt
Class (0 – 8 or “-“ )
Displays the advertised Class of the Power
Sourcing Equipment (PSE). The class
determines the maximum amount of power
the PSE can supply.
The PoE PRO will adjust its internal load and
attempt to pull the maximum power the
advertised Class supports. The chart below
cross-references Class to supported power.
A “-” will be displayed when the PSE does
not support 802.3af/at/bt negotiation. This
is typical of passive mid-span injectors that
apply voltage to the line regardless of the
connected network device.
Pass / Fail Indication
The test will pass ( ) if the power available
during the PoE load test is equal to, or
greater than the MINIMUM power for
PSE Class.
Example
: If class 4 is detected the test will
PASS if 25.5 W or more watts is delivered.
If less than 25.5 W watts is delivered the test
will FAIL.
