○
The battery pack may permanently lose some long term capacity.
○
Assuming a battery conditioning cycle is not started, a fully discharged
battery pack takes up to 3 hours before it is fully charged. If a battery
conditioning cycle is started, a fully discharged battery pack takes up to
24 hours before it is fully charged.
○
A battery conditioning cycle is started if the server is powered down for
longer than three months.
• A battery pack may be stored outside of the server for up to one year
before it must be charged and/or conditioned. After one year without being
charged and possibly conditioned, the battery capacity may be
permanently reduced.
If you store battery packs for more than one year, contact your
representative to find out about conditioning your battery packs.
• When preparing a server for shipment, if the NVRAM is still being backed
up by battery (indicated by the flashing NVRAM LED), the battery can be
manually isolated using the reset button. See
Reset button (RST) on
page 41 for the location of the reset button.
When preparing a server for shipment or if it will be powered down for any
length of time, it is important that the server has been shut down correctly
before powering-off. Otherwise, if the server is improperly shut down, the
batteries supplying the NVRAM will become fully discharged. This also
occurs if the system is powered down for too long without following the
proper shutdown procedure.
Note: If the batteries become fully discharged, or the system is to
be powered down for an extended period, see Powering down the
server for shipment or storage on page 74 . Contact customer
support for information about recharging batteries.
To replace the NVRAM battery backup pack, see Replacing the NVRAM
backup battery pack on page 52 .
