Appendix A Replacing and Upgrading FRUs
This appendix describes how to replace or upgrade the Field Replaceable Units (FRUs) in your
xStack Storage Array. FRUs that can be replaced or upgraded include:

Battery Pack

System and buffer memory

SATA drives

Fans

Power supplies
A.1 Installing the Battery Pack
The xStack Storage Array accommodates a 4-cell or 6-cell shrink-wrapped battery pack.
Because write-back caching is always enabled, we recommend you have a battery to back up
the buffer cache contents.
To install a battery in your xStack Storage SAN Array, follow these steps:
1. Hold the battery as shown to align the fastener pad. Make sure the battery cable and
connector is located nearest to the battery socket J35 on the controller (see Figure A-1 ).
