3.8 Volt The 3.8 Volt onboard supply is too low.
8 Volt The 8 Volt onboard supply is too low.
Pri Laser Fail The reverse path primary fiber laser is not sending light (no
light from remote unit to host unit).
Pri Rx Light No light is being received on the primary fiber (no light from
host unit to remote unit).
Pri Errors Multiple errors are occurring on primary fiber. Error rate has
exceeded 10
–6
(one bit error per million bits).
Pri Rev Mux Lock The reverse path primary fiber phase-locked-loop is out of
lock.
Fwd Synth Lock The forward path synthesizer is out of lock.
Pri Rev Synth Lock The primary reverse path synthesizer is out of lock.
Ref Synth Lock The reference synthesizer is out of lock.
System VSWR Voltage Standing Wave Ratio measured at the duplexer is too
high.
LPA Detect The LPA is “not present” when read (physically not there).
LPA Disable LPA has been disabled due to an alarm. For instructions on
clearing this condition, position the mouse cursor on this
indicator and read the text in the pop-up window.
LPA DC Fail Linear Power Amplifier (LPA) DC power is faulted.
LPA Loop Failed LPA has an internal loop failure.
LPA Low Power RF output signal level measured in LPA is too low.
LPA Over Power RF output signal level measured in LPA is too high.
LPA VSWR Voltage Standing Wave Ratio measured in LPA is too high.
Major Extern Input Major alarm input to the remote unit is faulted.
RF Power Forward path RF power (measured in duplexer) is too low.
