158823.01 PoE PRO
Extended Power Test
Activate the Extended Power Test by holding
the network button for 3 seconds until a
beep is heard.
This feature will attempt to draw up to
90 Watts of power from the PSE and can
be activated once a PoE measurement
has been made. Starting with the power
detected during the automatic PoE test,
the PoE PRO will increment power demand
in approximately 5-watt steps until the
either the PSE powers down or 90 watts is
reached. Each power step will be displayed
for one-half second.
Certain PSEs may be capable of delivering
power that exceeds the level defined by the
PSE’s Class in the IEEE 802.3 PoE standards.
The Extended Power Test sets the PoE PRO
to a mode that will not communicate a max
power limit to the PSE. In this mode the PoE
PRO will increase the power load until the
PSE shuts down the port or until 90 watts
is delivered. Carefully watch the display and
note the highest watt value displayed. If the
tester resets, the last number displayed is the
maximum power the PSE can deliver.
Certain high-power PoE devices do not
comply with IEEE 802.3af/at/bt negotiation
protocols. The PoE PRO can be used to
test in a no negotiation mode where it will
operate as simple PoE load and attempt to
draw 90 watts regardless of the PSE Class.
Pairs (2Pr / 4Pr)
Displays whether the PSE is supplying power
on 2 or 4 pairs of the connected cable.
2Pr is shown for 802.3af, 802.3at or some
non-standard compliant PoE injectors.
4Pr is shown for 802.3bt or some non-
standard compliant “HPoE” or “Ultra PoE”
injectors.
Pins (1 - 8)
Displays the pins of the RJ45 connector used
for PoE and the polarity of each pin.
A “+” below the pin number indicates a
positive DC voltage is present.
A “-” below the pin number indicates a
negative DC voltage is present.
If a pin is not used the area below the
number will be blank.
Mid-span vs End-point
Generally, an “end-point” PSE like a PoE
enabled Ethernet switch will use pins 1,2,3
and 6 for PoE.
A “mid-span” injector will generally use pins
4,5,7 and 8 for PoE.
The pin display can be used to determine
whether the PSE is a switch or injector,
although the IEEE 802.3 standards do not
call for this specific pin use.
