guration and Basic Service Manual Fans CAN Bus Commands
Fans CAN Bus Commands
The Fans CAN Bus Commands are used to verify the state of the Cooling Fans connected through CAN Bus.:
•
Use psu # get fan_con
fi
g or psu # get status to verify the number of fans installed in the system.
•
If psu # get alarm indicates that any of
FAN fail (1/2/3)
fi
elds equals
YES
, this means that a fan is failing.
•
psu # get psu_temperature - if the temperature is too hot this also in-
dicates a problem with cooling.
•
psu # get alarm will also show
Over temp.
alarm showing
YES
if the temperature is too high.
During initial commissioning, verify that fan con
fi
guration match the actual number of fans in the
system. If needed, use the psu # set fan_con
fi
g command to change the fan con
fi
guration.
Examples:
psu 1 set fan_config 1 1 1
to de
fi
ne three fans present on PSU1.
psu 2 set fan_config 0 0 0
to de
fi
ne no fans present on PSU2.
DPM CAN Bus Commands
The DPM CAN Bus Commands are used to verify the state of the Digital Power Meter:
•
dpm # get alarm - shows all the alarms related to the DPM
VSWR alarm: YES
- may indicate a broken antenna.
•
dpm # get fwd_power - if the reading is too low, it may indicate a broken
connection between the DPM and Base Radio.
ATCC CAN Bus Commands
The ATCC CAN Bus Commands are used to verify the state of the Cavity Combiners:
•
atc # get alarm - if there is at least one
Cavities VSWR Alarm
, it indicates
a problem with the Cavity Combiner.
•
atc # get cav_status <cav_number> - use this command for each Cavity Combiner.
Cavity VSWR Alarm
- this Cavity Combiner is unable to tune. An ac-
tual value of VSWR is shown.
Channel Spacing Alarm
- means that frequency of one Base Radio
is tuned too close to another.
atc # get cav_status <cav_number> will also list the frequencies of each Cavity Combiner,
this can be compared to the setting of the corresponding Base radio for veri
fi
cation.
