Motherboard Bus Bars
The hardware used to hold the busbar connections must be tightened using a
torque wrench set to 5 Newton meters (Nm).
Fit the motherboard cooling fan assembly.
Refit any expansion cards you may have removed to improve access.
It is vital that you remember the exact cable and connector arrangement of your
hard disks, particularly if you are using a RAID (Redundant Array of
Independent Disks) configuration. If you fail to restore the arrangement so that
all cables and plugs are as they were originally, you risk losing all the data on
your hard disks.
UPS Battery Pack
The UPS is equipped with a replaceable battery pack. It will provide electric
power for your system for a specific period of time, depending on how many
hard disks or other devices are installed. Use the SMA at any time to find out
the exact battery life remaining (see the SMA User's Guide for more details).
Do not attempt to remove the power supply if the battery pack has already
been removed, as it will cause a serious imbalance, the battery pack can
however be removed as an individual component.
