1.5.4 Support of PoE(+)
The device variants RSPE 32 and RSPE 37 support Power over Ethernet 
(PoE) and Power over Ethernet Plus (PoE+).
All Fast Ethernet ports are PoE-capable.
The Gigabit combo ports provide PoE support.
See “Device name and product code” on page 17.
 
The Fast Ethernet PSE ports allow you to connect network components as a 
PoE voltage sink according to the standard IEEE 802.3 10BASE-
T/100BASE-TX and IEEE 802.3af/at.
With the presence of the PoE power supply, a separate power supply for the 
connected device is unnecessary.
The PoE power is supplied via the wire pairs transmitting the signal (phantom 
voltage).
The individual ports (joint PoE voltage) are not electrically insulated from 
each other.
 
Maximum power available to PoE end devices in total:
124 W
Maximum power available to a media module:
62 W
Note: Connect only PoE-supplier devices whose data connections are 
located in the interior of the building and are specified as SELV circuits.
The PoE support complies with the following technical standards:
In accordance with IEEE 802.3af and IEEE 802.3at:
 Endpoint PSE
