Alarm Conditions
ALARM CONDITION
DESCRIPTION
DAS
band_mismatch
The frequency band in the RF module does not match the configured frequency
band.
boot_failure
A module failure has been detected during boot. The module has been identified
along with the error, under
Source
. If multiple modules fail, then multiple
boot_failure
entries will appear, each with different descriptions under
Source
.
firmware_error
This error indicates that a particular module's firmware needs an update or has an
error. The module's name is listed under
Source
.
frequency_lock_failure
The RF module cannot detect or lock the operator’s frequency band. This may
mean that the setup frequency is incorrect or that no signal is detected from the BTS.
gain_changed
This means the system’s uplink/downlink system gain has changed.
no_input_signal
A BU-RF module cannot detect a signal from its signal source.
out_of_service
The module is out of service and is not responding to the BU.
over_power
If the alarm source is the BU, this means the input power has exceeded 26 dBm. If it
is an RU, this means the output power has exceeded 26 dBm. In either case, the
device is under threat of damage from an exceedingly strong signal.
power_calibration_failure
A calibration process has failed.
storage_failure
A module cannot access its non-volatile memory.
unmounted_device
The system detects an unmounted Extender or RU. Please mount all connected
devices.
Equipment
awaiting_full_cooldown
An RU-RF module has overheated despite overheat prevention and the system has
shut down the module for cooldown.
bu_fan_error
ZoneDAS detects a fan speed threshold violation in the BU.
bu_overheat
ZoneDAS detects a temperature threshold violation in the BU.
extender alarm
A connected Extender has raised an alarm for either itself or one of its connected
RUs.
overheat_prevention
An RU-RF module is getting too hot and the system has reduced its power output to
prevent overheating.
hw_monitor_fail
There is a hardware monitoring failure.
pull_out
A BU-RF or BU-SD module has been removed.
ru_fan_error
ZoneDAS detects a fan speed threshold violation in the RU.
rf_module_overheat
Too much of the RU has overheated and the system has shut down the entire RU.
start_service
A module is ready to start service.
Management
alarm_cear
An alarm has been manually cleared.
fw_upgrade_notify
ZoneDAS has entered a firmware update process.
login_fail
There was a system login failure.
out_of_memory
The BU or Extender is close to using up its system memory.
vpn_link_fail
Cannot connect to Virtual Private Network (VPN). Please check VPN settings.
