Connecting Power Sourcing Equipment (PSE’s)
After installing the PowerSync Analyzer chassis, you can connect the Power Sourcing Equipment (PSE) to the
PSE Test Ports in the chassis.
Each PSEAF-2 test card (or equivalently, each
slot
on the PSA-100 or PSA-2400) has two pairs of RJ-45
connectors. The top pair is labeled OUT 1 and PS1 IN. The bottom pair is labeled OUT 2 and PS2 IN. Each pair
acts as an independent test port. In some tests you use both ports in the pair; in other tests you use only one of the
ports of the pair.
The PS1 IN and PS2 IN ports connect to the ports of an 802.3af PSE device. Use of the OUT 1 and OUT 2 ports is
optional.

Test Port LED Indicators
There are four LEDs on each test port: DET, PWR, ARM, and AUX. The LEDs are described below.
The LEDs toggle on and off at power-up and flash during the firmware upgrade process.
DET
- The DET LED is lit when the test port is in Detect Mode. Detect mode is present when the port is
connected (port connect), and the detection resistance is between 19k Ohm and 26k Ohm. When this LED is lit,
it’s an indication that the passive load is set up to allow a successful detection by a PSE, assuming that the ALT-
A/ALT-B and MDI/MDI-X settings in the correct state.
PWR
- The PWR LED is lit when the PSE voltage at the input port exceeds 33 Volts. If a measurement is active,
this LED may be delayed until completion of the measurement.
ARM
- The ARM LED is lit when the test port is armed and waiting for either an internal or external trigger.
This LED is shut off when the trigger occurs. (Note:
This LED is not utilized by PSA-PL
.)
AUX
- The AUX LED is lit during communications between the controller and the test port. It is also available
for possible user control in future software releases.
All four of the above LED’s toggle on and off at power-up, and flash during the firmware upgrade process.
