You can perform the following operations when a BBU fault alarm is reported and the alarm indicator is red:
Check the SES log and search keyword invalid OnlineTest (the online BBU test fails).
If the keyword exists, verify the BBU type in the SES log.
If the product name of BBU is HSCB1-62, the BBUs are BYD BBUs which may cause the problem. Replace BYD BBUs with SCUD BBUs (pay attention to the change during replacement).
