Installation MACH104-PoEP
Release 10 09/2019
21
The PoE support complies with the following technical standards:
The following applies to PoE ports:
 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:
240 W
Note: We recommend to distribute the PoE power equally between the two
port groups (ports 5 to 12 and ports 13 to 20).
1.6.6 Combo ports
You have the option of alternatively connecting a twisted pair cable via a
RJ45 socket or an optical fiber via a SFP transceiver to a combo port.
By inserting a SFP transceiver, you deactivate automatically the
corresponding twisted pair interface.
