Subscriber Unit Does Not Power-up
If you are having power up issues with your subscriber unit, verify power connections as

Also verify that the subscriber unit is connected to the Power & Data Out port of the indoor
power injector, and that the local network device is connected to the Data In port.
AN100U/UX Occasionally Reboots
Internal Device Issue
In this case troubleshooting your device is more difficult as the reboot may appear to occur
randomly. The most likely cause of an occasional reboot is a hardware fault.
Step 1
Check the event log as outlined in “Monitoring System Event Logs” on page 2-6. Look for
any unusual messages such as "P1 Watchdog reset.
Step 2
If you observe any such messages you need to capture the event log for further
investigation. See “Monitoring System Event Logs” on page 2-6 for instructions on
capturing the contents of the event log to a file.
When the device does reboot, you can now review the logged event information prior to
the reboot for an indication of the cause.
It is also possible that the device will provide a reason for the reboot during its boot
sequence.
External Power Source
Occasional reboots may also be caused by fluctuations in the power supply. Possible
external causes should be investigated, such as the quality of the external power source.
Step 1
Monitor and record your supply line voltage. If a device reboot corresponds to fluctuations
in the supply, you will need to resolve the power supply issue.
Step 2
If the system reboots without providing an error message and the power supply remains
consistent, you should try swapping out one component at the time in order to isolate the
cause.
Note
IDU power supplies are not field-swappable.
AN100U/UX Fault LED is Blinking
The blinking fault LED generally means that one of the AN100U/UX’s power supplies is
faulty or not connected properly.
