Installation MACH104-PoEP
Release 06 11/2013
The following applies to PoE ports:
The PoE voltage 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 terminal devices:
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 to alternatively connect F/O (via SFP transceivers) or
twisted pairs to a combo port.
When you are using an SFP transceiver, you get an optical interface. You
thus deactivate the corresponding TP interface.
1.6.7
SFP/XFP transceiver
