Temperature
Indicates the internal temperature of AP5857. It is typically 8°C higher than the external ambient temperature
due to self-heating of the radio circuitry.
Over Temperature Alarm
When active, indicates that the internal temperature exceeds the recommended operating limit (75°C) for
reliable operation. It will indicate “OK” or “Over Temperature”.
Hardware Failure Alarm
When active, indicates that there is a hardware failure in the radio. This usually requires the unit be sent back
to the factory for repair. It will indicate “OK” or “Fail”.
Downstream CATV Signal Validation
This indicates whether the internal cable modem is currently demodulating a valid DOCSIS downstream
signal. If so, it indicates “OK”. If not, it indicates “Signal Invalid”. The downstream RF signal will be muted
unless the state is OK.
