GS105PE - Non-PoE device on PoE port?

Is it possible to connect a non-PoE device (PoE PSE) to Port 2 without risking damage the non-PoE device? In other words, does the GS105PE detect when a non-PoE device is connected to one of the pass through ports and therefore does not supply any voltage to it, or is a pass through voltage present to both ports all the time?

Absolutely - in an IEEE standard PoE world (802.3af aka. 802.3at Type 1) "PoE", 802.3at Type 2 "PoE+", 802.3bt Type 3 "4PPoE"/"PoE++", and 802.3bt Type 4 "4PPoE"/"PoE++" there is no power supplied unless negotiated between the IEEE standards compliant devices. 

You get what you pay for - this isn't the el-cheepo dumb passive power thing which is still promoted as "PoE" 8-)  This is where the risk is.
