5-1-4 Batteries
One lithium battery on the motherboard and another on the RAS board are used to
back up the calendar, clock, and log data. The service life of these batteries is
approximately five years in an operating environment maintained at 25
°
C and is
shorter in environments with a higher ambient temperature. Replace the batteries
periodically depending on the operating environment.
Motherboard battery: NSA-BAT03
RAS board battery: NSA-BAT03

Guidelines for Replacing Batteries
The guidelines for replacing lithium batteries are as follows:
•
Five years have elapsed since a new battery was installed.
•
The BATLOW indicator on the RAS Board is lit (the RAS Board battery
only).
Note
•
Dispose of any battery that has been dropped on the floor or otherwise subjected to
excessive shock, as this may cause the battery fluid to leak.
•
Make sure you have the correct type of battery and that you install it properly.
•
Replace the battery yourself.
•
Operation may not be normal if a battery other than the specified battery is used.
