3.10.3 Forced Re­Calibration
Failure to ‘Disable’ the Installation Auto­Calibration option can
trigger an inadvertent re­calibration of the system, under certain
power failure conditions.
Option 1: Use the Auto­Cal function in the NMS ‘Maintenance screen. This function will store the
calibration values in non­volatile memory.
Option 2: Enable “installation auto calibration” in the NMS and ‘Apply Settings'. Disconnect the
DC power and fiber optic cables from the radio. Power up the radio while the fiber is still
disconnected. The Auto Calibration will start as soon as the fiber optic cable is reconnected to the
radio terminal.
When a radio is power cycled with the fiber connected to network equipment, the radio will use the
calibration values stored in non­volatile memory from the last successful auto­calibration process
even if the enable Auto­Cal setting being set to ‘Enable’. The radio link will come up immediately.
When a radio has “Installation Auto Calibration” disabled, the radio will use the calibration values
stored in non­volatile memory from the last successful auto­calibration process, regardless of the
fiber interface connected to network equipment or not.
Should moving the link to a new location or re­alignment of the
link become necessary, the link must be recalibrated per the autocalibration
procedure described in Section 3.10.
