module in order to reach the intended location of the remote
battery board.

Installing Your 3ware RAID Controller” on page 11 for details.
Installing the Remote Battery
1 Remove the metal filler brackets for the expansion slot in
which you have decided to install the remote battery board.
Save the screws; they will be used to secure the remote battery
board after you have installed it in the slot.
2 If your enclosure is low-profile, unscrew the full height bracket
from the remote battery board and replace it with the included
low-profile bracket, using the same screws.
