PoE ports

PoE ports of the SCALANCE XR324-4M PoE and XR324-4M PoE TS switches
As PSEs, these devices supply PoE-compliant devices with power over Ethernet. The power
required to supply the powered devices is generated internally on the switches, no extra
power supply unit is necessary.
The switches use the "Alternative A" method. Per RJ-45 port, a maximum of 15.4 W are
available for supplying a PoE-compliant device. If a Cat5/Cat5e cable with a maximum
length of 100 m is used, the connected device can be supplied with a power of 12.95 W.
Note
The total power provided by the switches on all eight PoE ports is a maximum of 53.2 W.
The PoE ports meet the conditions listed in the IEEE 802.3af / IEEE 802.3at standard
(type 1) for environment A , in other words power supply over Ethernet within a power supply
system. For details of configuring and enabling PoE for individual ports, refer to the
configuration manual SCALANCE X-300 / X-400 on the accompanying CD.
4.3.1.6

Isolation between the TP ports

All ports meet the requirement of 1.5 kV isolation voltage to the shield and between the ports
(corresponds to IEEE802.3, Environment B).
Note
Exceptions are X307-3, X307-3LD, X308-2, X308-2LD, X308-2LH, X308-2LH+, X310,
X310FE
The following port group is an exception to this:
• Port group 1: P1, P2, P3 and P4
Between the ports of port group 1, the requirements for Environment A are met.
