Description of the device
2.7 Power over Ethernet (PoE)
PoE ports
● The PoE ports are M12 sockets. Ports P5 to P8, P13 and P15 are D-coded, ports P14
and P16 are X-coded.
● Depending on the connected power supply, the device can supply power consumers of
the standard IEEE 802.at type 1 or type 2
● The PoE ports are not isolated from each other. This means that they meet the conditions
named in Environment A (IEEE 802.3): Power supply over Ethernet within a power supply
system.
The electrical isolation of the ports is designed for 500 Vrms (1 minute).
● The PoE ports are divided into port groups:
– Ports P5 to P8
– Ports P13 to P16
Devices with 8 ports have one port group, devices with 16 ports have two port groups.
● In total a power source can make a maximum of 120 W (incl. line losses) available. The
power can distributed to the port groups variably.
● Note the line losses. For example to supply power consumers with approx. 102 W, the
connected PoE power supply must make at least 120 W available.
● If you use a Cat5/Cat5e cable with a maximum length of 100 m, the connected device
can be supplied with a power of 25.5 W.
Note
Turn off the power source before you disconnect the PoE cable of a power consumer.
Configuration
How you activate and configure PoE is described in the configuration manuals, see section
"Introduction (Page 3)", section "Documentation on configuration".
