To locate and handle power failures, follow the procedure as described below.
Flowchart
The flowchart is shown in the following figure.
Procedure
- Measure the input voltage. Use a multimeter to measure the input voltage, and assess whether the input voltage falls outside the working voltage range.
- Connect and disconnect the power adapter. Connect and disconnect the power adapter and the power cable to exclude loose connections.
- Cross-check the power adapter and the Smart Access Gateway (SAG) device. Connect the
current power adapter to a functioning SAG device, or connect a functioning power
adapter to the current SAG device.
- If power failures occur after you connect the current power adapter to a functioning SAG device, repair the current power adapter.
- If power failures occur after you connect a functioning power adapter to the current SAG device, submit a ticket to repair the current SAG device.
