The XR324-4M PoE is a partially modular device and has 16 fixed ports and 4 slots for
media modules.
● 16 electrical ports
– Ports P1 to P8
8 PoE-compliant RJ-45 jacks with securing collars for connection of end devices or
network segments
– Ports P9 to P16
8 RJ-45 jacks with securing collars for connection of end devices or network segments
(no PoE)
Non PoE-compliant end devices can also be connected to the PoE-compliant RJ-45 jacks
because the XR324-4M PoE checks that the end devices are suitable for the PoE
function before applying the power.
● 8 modular ports via 4 module slots
4 media modules each with 2 ports are combined optically or electrically via the slots S1
to S4 depending on the application.
End devices and other network segments are connected according to the media modules
being used.
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
