Power on LAN Ethernet Ports
The OS7-ENI-P24 module provides 24 Ethernet ports;
these ports can be used in conjunction with Alcatel’s
Power over Ethernet (PoE) feature. PoE provides
inline power to connected devices. Refer to “Managing
Power over Ethernet (PoE)” in the Hardware Users
Guide for detailed information on the feature.
The PoE ports are twisted-pair and are individually
configurable as 10BaseT or 100BaseTX. The ports use
RJ-45 connectors.

Ethernet Port Link Status LEDs
Each Ethernet port has a built-in corre-
sponding status LED located at the top of
the port. This LED indicates the link and
activity status for each Ethernet port. The
LED displays green when a valid Ethernet
cable connection exists. Flashes green as
data is transmitted or received on the port.
Ethernet Port Power LEDs
Each Ethernet port has a built-in corre-
sponding power port LED located at the
bottom of the port. This LED displays solid
green when power is properly supplied to
the port. Flashes green when there is an
overload or short. And this LED is off if
there is a power failure.
