This section describes how to remove and replace the battery backup
unit (BBU) in a DXi6902 Array module (RBOD).
Caution: Use appropriate ESD precautions, including the use of a
grounding strap, when performing this procedure.
Removing and replacing an Array module BBU includes the following
steps:
• Identifying a Failed Array Module BBU
• Removing a Failed Array Module BBU
• Installing a Replacement Array Module BBU
Identifying a Failed Array Module BBU
The DXi6902 contains one or two Array modules (RBODs). Each Array
module contains two controllers (A and B), and each controller contains
a battery backup unit (BBU).
To identify the Array module controller with the failed BBU:
1 Access the remote management console (see Accessing Remote
Management on page 23).
2 Navigate to the Status > Hardware > Details > Storage Arrays
page.
3 Note the status of the battery in each Array module (see
Figure 111 ).
Note: Qarray1 corresponds to RBOD 1 and Qarray2 corresponds
to RBOD 2. Slot 1 corresponds to controller A and slot 2
corresponds to controller B.
