Power Over Ethernet (Poe); Poe Pd Usage - Advantech SmartFlex SR304 Hardware Manual

3. Router Design

3.9.7 Power over Ethernet (PoE)

Available only for models with PoE feature; see Chapter
You can not power the router via the ETH2 ports on the SWITCH router version. The PoE PD is available
on the ETH0 and ETH1 ports only.
The IEEE 802.3af/PoE (Type 1) and IEEE 802.3at/PoE+ (Type 2) standards are supported. The device is
Mode B compliant.
You can use the pse command to control the PoE functionality; see the
note.
Based on the model configuration, the PoE PSE or PoE PD feature can be supported for both Ethernet
ports (ETH0 and ETH1).
The PoE PSE version allows the router to power other devices over the Ethernet. The PoE PD version
enables the router to be powered by another PoE PSE device over the Ethernet.
PoE PD
The PoE PD parameters can be found in Chapter 5.8. The POE LED on the front panel of the router
lights up green when voltage is present on 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 must 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 still be powered from the Ethernet
connector via PoE.
