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.
