7- 21
RFU High Temperature
Definition
: This indicates when the temperature of the IRFU transceiver has risen above
either of two thresholds:
•
If the temperature exceeds the High Temperature threshold, the transmit power may
reduce.
•
If the temperature exceeds the Very High Temperature threshold, the transceiver will
mute the transmitter.
Cause and action
: This could be caused by failure of the IRFU transceiver fan assembly.
Check if there is an active fan alarm:
•
If there is no active fan alarm, check that there is nothing obstructing the correct
operation of the fan assembly.
•
If nothing is obstructing the fan assembly, ensure that the IRFU has been installed
correctly and in an environment which is in line with specifications.
RFU RF Switch
Definition
: For a 1+1 IRFU, both the Primary and Secondary transceivers transmit but
the energy from only one of the transceivers is switched to the antenna via an RF switch.
The RF switch resides in the branching unit of the IRFU. This alarm is displayed if the RF
switch fails to switch.
Cause and action
: The most likely cause is a failure of the IRFU RF Switch. Please inform
Customer Support of this alarm.
RFU RF Switch Cable
Definition
: For a 1+1 IRFU, both the Primary and Secondary transceivers transmit but
the energy from only one of the transceivers is switched to the antenna via an RF switch.
The RF switch resides in the branching unit of the IRFU and connects to each transceiver
with a separate cable. This alarm is raised if the transceiver cannot detect the RF Switch.
Cause and action
: The most likely cause is that the cable connecting the transceiver to
the RF switch is faulty or disconnected.
RFU Rx IF Synth Lock
Definition
: This indicates a failure of the Rx IF synthesizer in the RFU.
Cause and action
: This is a failure of the RFU hardware. Please inform Customer Support
of this alarm.
