11.9.3 Time
Time threshold defines how many seconds the alarm should be measured as in error
before an alarm is triggered.
11.9.4 Upper
Upper threshold is maximum voltage level * 100 of the power supply before an alarm is
triggered. For example, configuring the upper level as 660 means that if voltage level
exceeds 6.60 V, an alarm is triggered.
11.9.5 Lower
Lower threshold is minimum voltage level * 100 of the power supply before an alarm is
triggered. For example, configuring the lower level as 610 means that if voltage level
drops below 6.10 V, an alarm is triggered.
11.10RBT – Radio Board Temperature
11.10.1Description
Temperature is constantly monitored on the Rack Communications Board (RCB) and in
the FiberOptic Masters (FOMASTER).
An alarm will be triggered temperature board temperature is outside allowed interval. A
radio board with a too high temperature might cause decreased radio performance and
will lower MTBF on the entire Optical Master Unit.
11.10.2Threshold Usage
By default, both upper and lower thresholds are used in the RBT alarm.
11.10.3Time
Time threshold defines how many seconds the alarm should be measured as in error
before an alarm is triggered.
11.10.4Upper
Upper threshold is maximum temperature in Celsius * 10 allowed on the board before an
alarm is triggered.
For example, upper threshold set to 750 means that if board temperature increases above
75.0 Celsius, an alarm is triggered.
11.10.5Lower
Lower threshold is minimum temperature in Celsius * 10 allowed on the board before an
alarm is triggered.
For example, lower threshold set to -100 means that if board temperature drops below
-10.0 Celsius, an alarm is triggered.
11.11RXO - Recieved Optical Level
11.11.1Description
The Fiber Optic Masters constantly monitors received optical level. A too low optical
input level might indicate that there is something wrong with the slave transmitter, a bad
optical connection (poor soldering or cleaning) or a broken fiber.
11.11.2Threshold Usage
By default, only lower threshold is used.
11.11.3Time
Time threshold defines how many seconds the alarm should be measured as in error
before an alarm is triggered.
