When an active network is detected but no SignalTEK NT Remote Unit, select the TESTS icon
from the home screen (Fig 38) and the Tests screen (Fig 39) is displayed. In addition to
Autotest, (described in Tests menu description – Cable mode ) POE and Blink tests can be run

PoE
When the Near-End Unit is connected to a port it
automatically detects PoE voltage (when present). In
addition, running a PoE test will apply a resistive load and
measure the power available at the connected port.
SignalTEK NT identifies which pairs are carrying power, and
displays the voltage (V), current (mA) and power (W). The
PoE test result screen at Fig 41 shows that pair one and
two, and pair three and six are carrying 11 Watts. The port
tested is capable of powering devices that require upto 11
Watts.
The test is PASSED because the power available is ≥ the
minimum power value entered at set up.

Blink
A Hub Blink test forces the connected port of a network device to blink. SignalTEK NT also
changes the speed and therefore LED color (on supporting devices) making it easier to
identify the correct port. Select the BLINK icon from the Tests screen, the test is started and
stopped with the soft key F1 which displays as RUN or STOP accordingly.
