The proper way to replace the motherboard battery is to power off the server and drain the remaining power out of the server by holding the power button in for 30 seconds while the server is unplugged. Then physically replace the battery and power on as normal.
As far as the possibility of losing you data/settings. Depending on the RAID controller you have installed on the server it will normally have a RAID Battery attached that powers the RAID memory and keeps the settings cached. This should not be affected by the replacement of the motherboard battery.
The RAID battery is typically connected by a cable to the RAID controller card or riser.
The motherboard battery (CMOS) is a small coin cell battery about the size of a nickel.
