Mediatrix 4100
LED Indicators
A LED can be ON, OFF, BLINKING or controlled by hardware (HW). The blinking behaviour is described in
terms of rate (in Hertz – Hz) and duty cycle (in percentage). For instance, a LED that turns on every two
seconds and stays on for one second would be described as: blink 0.5 Hz 50%. The hardware (HW) behaviour
is not defined. It is usually the standard state for the LAN LED.
Ready LED
The Ready LED provides an “at-a-glance” view of the Mediatrix 4100 operational status. It is an aid for
installation and on-site support. This LED is:
 ON when all elements of the ifAdminOpState column are “enabled”.
 OFF when all elements of the ifAdminOpState column are “disabled”.
 Blinking when at least one element of the ifAdminOp State column is “enabled” and at least one
element is “disabled”.
Patterns and meanings of the Ready LED are described in Table 8 on page 16.
Refer to the MIB Reference Manual for more details on the ifAdminOpState variable.
In Use LED
The In Use LED provides feedback of the activity on the line. If a line is ringing, off-hook, or displaying
information (ADSI), then this LED is ON. The In Use LED is ON when at least one element in the
ifAdminUsageState column is “busy”. Patterns and meanings of the In Use LED are described in Table 8 on
page 16.
Refer to the MIB Reference Manual for more details on the ifAdminState variable.
LAN LED
The LAN LED provides the Link and Heartbeat status of the network connected to the ETH1 and ETH2
connectors. If there is no link under HW control, the LED is OFF. When a link is established, but no activity is
detected, the LED is ON; it turns off for very short periods of time when activity is detected and blinks rapidly
when the LAN is loaded. Patterns and meanings of the LAN LED are described in Table 8 on page 16
.
Power LED
The Power LED indicates whether or not the Mediatrix 4100 is operational at its most basic level. It does not
imply that the unit can be used, only that it is capable of being used. Healthy operation would be steady ON.
Patterns and meanings of the Power LED are shown in Table 8 on page 16.
LED Patterns
Table 6 describes the different states a Mediatrix unit can have and their associated LED patterns.

Normal
Mode
“Normal” state of the unit where calls can be
initiated. Each LED has a separate behaviour.
