Pri Rx Errors Multiple errors are occurring on primary fiber. Error rate
has exceeded 10
–6
(one bit error per million bits).
Pri Fwd Mux Lock The forward path primary fiber phase-locked-loop is out
of lock.
RF Overdrive The forward path RF signal level is too high.
Hardware Mismatch Host unit and remote unit are on different bands.
Remote Lost Host cannot communicate with remote unit.
EMS Link Status EMS has not heard from host unit for the number of
minutes currently specified by the EMS Link Timeout
parameter (see Topic Topic 3.6, Setting EMS Link
Timeout, Cataloging Time, Demo Mode, on page 34).
Ref Synth Lock The reference synthesizer is out of lock.
Host FPGA Fault Fault was reported in FPGA chip on Host PCIx Card.
Table 11: Host Minor Alarms When Faulted
ALARM NAME DESCRIPTION
Temperature The host unit temperature is too hot. The temperature is
sensed to be greater than 70º Celsius (158º Fahrenheit).
Likely cause is a fan failure.
Sec Rx Light No light is being received from the secondary fiber (no
light from host unit to remote unit).
Sec Rx Errors Multiple errors are occurring on the secondary fiber.
Error rate has exceeded 10
–6
(one bit error per million
bits).
Sec Rev Synth Lock The secondary reverse path synthesizer is out of lock.
RF Underdrive The forward path RF signal level is too low.
B Laser Fail Not used. Always green.
B Laser Mux Fault The secondary fiber phase-locked-loop is out of lock.
