Important Pre-installation Considerations

Warning: Always ground yourself and/or use a ground strap before touching the RAID controller or
the Intel
safe workstation. Use an ESD-safe Phillips* screwdriver set to a maximum torque of 2.25
inch-pounds, and be sure the screwdriver is centered in the screw to avoid damaging the
screw head. If you exceed the maximum torque specification, you may damage the board,
connectors, or screws, and you will void the warranty of the board.
The batteries in the Intel
hours during fast charge, under normal operating conditions.
To protect your data, Intel recommends that you set the RAID Controller Write Policy to
write-through until the battery unit is fully charged. When the battery unit is charged, you
can change the Write Policy to write-back to take advantage of the performance
improvements of data caching.
The maximum ambient temperature for the battery pack is shown in the following tables.
