assembly from the antistatic shipping container until you are ready to install

its original container.
c. Check the appropriate support Web sites for the latest updates for your
basic input/output system (BIOS) code, utility programs, device drivers,
and other software applications. Follow the instructions provided by your
Service Provider to download and install updates.
d. It is recommended that you replace the battery pack on the battery card
assembly annually or after 500 recharging cycles, whichever comes first.
e. The temperature of the battery card assembly is generally 15–20 degrees
higher than the ambient temperature during fast charge. Therefore, to
complete fast charge cycle, the ambient temperature should be less than 45
degrees. If the ambient temperature exceeds 45 degrees, the fast charge
cycle will terminate prematurely, thus preventing the battery card assembly
from reaching a fully charged state.
Attention:
v When attaching the battery card assembly to a PCI Express slot, center the
Phillips-head screw driver to avoid damaging the screw head and do not
over-tighten the screws as you might damage the battery card assembly.
v The battery in the battery card assembly must recharge for at least six hours
during fast charge under normal operating conditions.
