14 Mediatrix 4104
LED Behaviour in Starting Mode
When the Mediatrix 4104 starts and it is not configured to use a DHCP server, it uses static IP addresses. If
the static information is not valid, the
LAN LED blinks at 1 Hz with 75% duty cycle. This lets you know that you
must perform a Factory reset or Recovery mode operation. See “Reset / Default Switch” on page 18 for more
details.
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
ETH1/ETH2 LED.
Ready LED
The Ready LED provides an “at-a-glance” view of the Mediatrix 4104 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 9 on page 17 .
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 9 on
page 17 .
Refer to the MIB Reference Manual for more details on the ifAdminState variable.
ETH1/ETH2 LEDs
The ETH1 and ETH2 LEDs provide 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 Ethernet is loaded. Patterns and meanings of the
ETH1 and ETH2 LEDs are described in
Table 9 on page 17 .
Power LED
The Power LED indicates whether or not the Mediatrix 4104 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 9 on page 17 .
