Case 2) When Alarm indicator
Problem Check Point Solution
General Tamper detected Install the BDA at the System and set up the
Lock using the WEB GUI.
Alarm occurred when the BDA unequipped
without cancellation of Lock for setting.
Power supply out of range - Check if the input power is AC85-264V and if it
is normal, Contact Technical Support.
Communication failure Check the status of the Data Cable connection.
If communication failure occurred at every
connected BDA, Reset the MCU.
If communication failure occurred at a particular
BDA, Reset BDA for the occurred failure.
Field replaceable module
failure
If the same alarm occurs after resetting the
BDA, request technical support.
Reset alarm Do not control anything during the reset.
Manual shutdown alarm If it has no problem regarding the installation,
the HPA is On.
Heartbeat Check the connection of the Remote NMS
Cable.
Check the interval of Heartbeat on the WEB
GUI.
Uplink Oscillation detected Check Donor/Server antenna Isolation value. If
the gain value is lower than +5dB, adjust the
antenna location to secure Isolation.
Power at coverage port too
high
If the UL Input Power is too high, check the
Coverage antenna of the initial installation again.
Synthesizer failure If the same alarm occurs after resetting the
BDA, request technical support.
Hardware failure If the same alarm occurs after resetting the
BDA, request technical support.
Software failure If the same alarm is occurs after resetting the
BDA, request technical support.
Out-of-band emissions out of
spec
It may occur when VSWR is too high and need
to adjust the antenna location.
Downlink Donor Power too high/low Check the DL Input Power, need to adjust the
antenna location.
Low isolation Check Donor/Server antenna Isolation value. If
the Gain value is lower than +5dB, adjust the
antenna location to secure Isolation.
Synthesizer failure If the same alarm occurs after resetting the
BDA, request technical support.
Hardware failure If the same alarm occurs after resetting the
BDA, request technical support.
Software failure If the same alarm occurs after resetting the
BDA, request technical support.
Spurious emissions out of
spec
It may occur when VSWR is too high and need
to adjust the antenna location.
Interferer power exceeded It may occur when VSWR is too high and need
to adjust the antenna location.
