Avaya MM314 Media Module LEDs
The MM314 Media Module is a LAN Media Module that provides:
•
24 Ethernet 10/100 Base-T Ethernet access ports with inline Power over Ethernet (PoE).
•
One Gigabit Ethernet 1000 uplink/access port.

Alarm LED
The MM314’s alarm (ALM) LED is located on the lower left corner of the front panel. The ALM LED
indicates that an alarm is present in the module, or that Communication Manager (CM) has the slot
administered for a Voice Media Module.
Port LEDs
On the left side of the MM314’s front panel are numbered LEDs that correspond to each of the MM314’s
network ports. Underneath these LEDs is a row of LEDs that indicate particular functions. The function
LED that is lit indicates which function the network port LEDs are reporting. For example, if the LNK
LED is lit, the port LEDs indicate whether the network links for the specific ports are functioning
properly.
To the right of the function LEDs are two push buttons. Use these buttons to select the function you want
the port LEDs to report. For example, if the COL LED is lit, all the port LEDs are reporting the Collision
status of their respective port. The following table shows each of these functions:
LED Name Meaning
LNK Link If the port LED is lit, the port is enabled and the link is
working properly.
COL Collision If the port LED is off, there has been no collision on line.
If this LED is flashing, there are collisions occurring.
Tx Transmit to line If the port LED is lit, data is being transmitted.
Rx Receive from line If the port LED is lit, data is being received from the line.
FDX Half/Full Duplex If the port LED is lit, the line is operating in Full Duplex
mode. If the port LED is off, the line is operating in Half
Duplex mode.
