8.9 Recovery Procedures
Recovery Procedure is used to restore the device to its factory default operating state. Depending on the device state, the
recovery procedures can be classified under two modes:
1. Operational Mode: Device is up and in running state.
2. Bootloader Mode: Device operating image is deleted.

Data Rate Issues
– Ensure same data rates are selected if you are using fixed data rate between
BSU/SU and End Point A/End Point B to have predictable throughput and link
– Alternatively, use DDRS with Auto mode enabled
`
Performance and Stability Issues
– Check the distance between two co-locating devices. The distance between
two co-locating devices should be minimum 3 meters, in order to achieve
good throughput and maintain link stability. The operating adjacent channel
should maintain 5MHz spacing if managed by a single administrator.
– When DDRS is disabled, check the Minimum Required SNR for the current
data rate by navigating to MONITOR --> WORP Statistics --> Interface 1
--> Link Statistics Page --> Click here for Local SNR-Table. If the current
SNR is not meeting the minimum required SNR criteria for the current data
rate, then accordingly reduce the data rate.
– If SNR is more than the maximum optimal SNR limit (MONITOR --> WORP
Statistics --> Interface 1 --> Link Statistics Page --> Click here for Local
SNR-Table) then it causes radio receiver saturation thus impacting the
performance of the link. To overcome this situation, set the TPC appropriately
or enable ATPC to adjust the signal level automatically. Also, enabling DDRS
can help in choosing right data rate automatically.
– To measure and diagnose any performance issues in the wireless link, use the
Radio Link Test Tool. To use this tool, navigate to MONITOR --> WORP
Statistics --> Interface 1 --> Link Statistics Page --> Details -->Click
