Poe Pse Usage - Advantech SmartMotion ST355 User Manual

The PoE PD parameters can be found in Chapter 7.8. The POE LED on the front panel of
the router turns on with the green light on the voltage present in an Ethernet port so the user
knows the router can be PoE powered. You can still power the router with this connector even
if the router is powered with PoE (in PoE PD version), but the input voltage have to be higher
than 15 V DC. If the input voltage is lower than 15 V DC and the PoE voltage is present (PoE
LED green on), the router will be still powered from Ethernet connector via PoE.
Note: you can not power the router via SWITCH version ETH2 connectors. The PoE PD
is available on the ETH0 and ETH1 ports only.
PoE PSE
Power supply used with the PoE PSE router has to provide the voltage from 44 to 57 V DC
and the output power has to be at least 65 W for full PoE+ use (Class 4) in both Ethernet
ports (ETH0 and ETH1).
The PoE PSE parameters can be found in Chapter 7.8. The state of PoE is indicated by
the POE LED on the front panel of the router, see Chap. 5.8.1. The sufficient voltage (44 to
57 V) and power available is indicated by the green light. Yellow color of POE LED indicates
unsufficient power or voltage on PWR connector. When a device is powered from the router,
the POE LED is blinking green. Yellow blinking is for overload (the powered device takes too
much power) or short circuit (incorrect wiring of the cable or the device without PoE support).
You can enable or disable the PoE PSE feature separately on ETH0 and ETH1 ports via
the Web interface of the router. It can be found in the LAN configuration (Primary for ETH0,
Secondary for ETH1). When PoE PSE is enabled, you can find the current, voltage, power
and power class information on General page of router's Web interface. See Configuration
manual [2]. Via SSH or in scripts you can use the Shell command pse.
