6 ERROR CONDITIONS AND CORRECTIVE ACTIONS
When the internal BITE (Built In Test Equipment) in the transmitter or the receiver units detects a
failure, the alarm indicator on the front panel of the unit will be lit. In addition the radio unit will
signal with an automatically generated SNMP trap message on the ethernet interface.
Details about the fault that caused the alarm are accessible for user access levels: SysOp and
Technician.
The error messages are available in two levels, first the module that has the failure will be identified,
next the user has the option to view in details what particular message that caused the alarm
condition.
In the following (LRU) refers to the Lowest Replaceable Unit – and is normally the first line
maintenance where the complete unit is replaced. (LRM) refers to the Lowest Replaceable Module
and is the module within the unit that can be replaced. The LRM level normally requires a well
equipped workshop with appropriate tools for testing and calibration.
