DSN-1100 Hardware Reference Guide 27

A.2 Installing the Battery Pack

The xStack Storage Array accommodates a shrink-wrapped battery pack. Because write-back

caching is always enabled, we recommend you have a battery to back up the buffer cache

contents.

The battery pack connects to the DSN-1100 controller board using a 3-pin locking connector at

J11 (see Figure A-3 for detailed drawing of its location). The battery itself is attached to the

chassis by means of two 3M Dual Lock re-closable fastener strips, which allow easy field

replacement of the pack, if required.
