NOTES:
1. RF power sensor floor is approximate, -62 dBm.
2. In general, the Warning columns indicate values at which system faults are logged and/or system software
takes action.
3. Low Bad SNR and RSSI are characterized values at which uncorrectable errors are likely to occur.
4. Chassis fan speed is controlled in three steps based on load and temperature—the warning levels correspond
to each of the fan speed steps.
