6.2.2.1 Fault/Alarm Display and Description
This section consists of general fault, status, and alarm information that is indicated by
the 10 LEDs on the front panel. The LEDs indicate the following information is in the on
condition.
Faults
Name
Color
Description
TX
Red
A fault condition exists in the TX chain.
RX
Red
A fault condition exists in the RX chain.
Common
Red
A common equipment fault condition exists.
Stored
Yellow
A fault has been logged and stored. The fault may or may not
be active.
Status
Name
Color
Description
Power ON
Green
Power is applied to the modem.
Transmitter ON
Green
Transmitter is currently on. This indicator reflects the actual
condition of the transmitter, as opposed to the programmed
condition.
Carrier Detect
Green
Decoder is locked.
Test Mode
Yellow
Flashes when the modem is in a test configuration.
Alarms
Name
Color
Description
TX
Yellow
A TX function is in an alarm condition.
RX
Yellow
A RX function is in an alarm condition.
A fault (red LED) indicates a fault that currently exists in the modem. The LED is turned
off when the fault clears.
When a fault occurs, it is stored in the stored fault memory and indicated by the single
yellow LED. If the fault clears, the occurrence is also cleared.
A total of 10 occurrences of any fault can be stored. Each fault or stored fault (indicated
by a front panel LED) is the sum of many faults. To determine which fault has occurred,
use the Fault or Stored Fault front panel menu.
Alarms are considered minor faults which will not switch the modem offline in a
redundant system. Alarms are shown in the Fault or Stored Fault front panel menu by a
reversed contrast “
+
”.
