SmartMotion ST355
5.9.7
Power over Ethernet (PoE)
Available only for models with PoE feature; see Chapter
for the order codes.
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
application 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.

Figure 20: PoE PD usage
The PoE PD parameters can be found in Chapter
. 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.
