Important Pre-installation Considerations
Warning: Always ground yourself and/or use a ground strap before touching the RAID controller or
the Intel
®
RAID Smart Battery AXXRSBBU7. Perform all installation work at an ESD-
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
®
RAID Smart Battery AXXRSBBU7 must charge for at least six
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 40° C.
Note: The temperature of the battery pack is generally 15-20 degrees higher than the ambient
temperature during fast charge. Therefore, to complete the fast charge cycle, ambient
temperature should be less than 40° C. If the ambient temperature exceeds 40° C, the fast
charge cycle will terminate prematurely, thus preventing the battery pack from reaching a
fully charged state. Intel recommends mounting the battery remotely from the RAID
controller when possible to provide additional cooling.
