4.2.2 AISG/OOK Overcurrent Alarm Handling

Background
If the ALD connected to the AISG or OOK port on the PAA has overly strong current or is
short-circuited, the PAA forcibly shuts down the external power supply and an AISG/OOK
overcurrent alarm is reported.
Table 4-2 describes the AISG/OOK overcurrent alarm.
Draft A (2015-06-12)
If the PAA communicates properly with the smartphone and the alarm is cleared after the
restart, no further actions are required.
If the alarm persists, the PAA has been damaged. In this case, replace the PAA with a
new one or contact Huawei technical support.
