Parameters of I/O Ports
Electrical characteristics of the binary inputs are in Table
. Status of the binary input can
be retrieved in the router’s web interface (on the
General Status
page) or by the
status ports
and

Parameters of PoE
Dedicated models support the PoE PSE funcionality, see Chapter
. All four ETH0 ports
can be used for this purpose.
Standards IEEE 802.3at-2009 (PoE+) and IEEE 802.3af-2003 (PoE) are supported. Ca-
bling needed is Category 5, up to 12.5
Ω
