Press ENTER and use the arrow keys to move across the “-“ and “+” characters. Each
character represents a possible alarm. The “-“ character indicates the element in question is
NOT in alarm. The “+” symbol indicates the element is in an alarm (fault) state.
Possible alarms are as follows:
Type
Alarm
State
Unit
MainPs X.X
Main Board Power Supply Fault
(3.3V, 1.5V, 1.2V, 1.8V, 1.0V, 2.5V, 1.25V)
MdmBdPs X.X
Modem Board Power Supply Fault
(5.8V, 3.8V, 2.8V, 3.3V, 1.5V, 1.2V)
Pwr Cal
Transmit power is not factory calibrated. Contact CEFD Product Support.
FPGA Load
An FPGA could not be configured.
Ref Unlock
Unit could not lock to external reference clock input.
Unit Temp
Unit has exceeded operating temperature.
Unit Fault
A general unit fault.
PIIC1 ExtClk Act
A PIIC interface has been selected and the clock is set to lock to an
External Clock (as with G.703 or other Synchronous PIIC cards), however
no clock signal is detected.
PIIC1 ExtClk Out of
Range
A PIIC interface has been selected and the clock is set to lock to an
External Clock (as with G.703 or other Synchronous PIIC cards), however
the clock signal does not match the expected clock rate.
PIIC2 ExtClk Act
A PIIC interface has been selected and the clock is set to lock to an
External Clock (as with G.703 or other Synchronous PIIC cards), however
no clock signal is detected.
PIIC2 ExtClk Out of
Range
A PIIC interface has been selected and the clock is set to lock to an
External Clock (as with G.703 or other Synchronous PIIC cards), however
the clock signal does not match the expected clock rate.
Log File Fault
The file that is used to save all logging data regarding modem parameters
is missing or corrupt.
Int 250 PLL
The modem's internal 250MHz clock out of range or has failed.
Int 900 PLL
The modem's internal 900MHz clock out of range or has failed.
MEO Mdm: Mdm
Comms
The modem has been set to run in MEO mode and the communication
between the remote Tx/Rx modem and remote Rx demod is timing out or is
getting corrupt / unexpected.
MEO Over Air comms
The modem has been set to run in MEO mode and the communication
between the remote Tx/Rx modem and hub / gateway Tx/Rx modem is
timing out or is getting a corrupt / unexpected response.
