The BBU that you want to replace has been located.
NOTE
You can locate a component in either of the following ways:
l Locating a component based on alarms in DeviceManager: On the Alarms and Events page of
DeviceManager, view the help information and locate the component to be replaced.
l Locating a component based on the status of its alarm indicator: For details about the indicators on
different components, see indicator introduction in the Product Description specific to your product.
The two BBUs are installed in two power modules. Therefore, remove the power
modules before removing the BBUs.
When a BBU is being replaced, the power module where the other BBU resides is
working properly.
Remove and insert a BBU with even force. Excessive force may damage the appearance
or connectors of the BBU.
Remove only one BBU at a time.
A BBU must be replaced within three minutes. Otherwise, the system heat dissipation is
compromised.
