System board Removal/installation routines
Lithium battery
So that important system information (e.g. configuration) can be permanently
saved, two lithium batteries are installed which supply the CMOS memory with
a current. A corresponding error message is displayed when the battery voltage
is too low or the batteries are empty. Both lithium batteries must be replaced
immediately.
Replacing the lithium battery
Requirements
– server has been switched off
– power cords have been disconnected
– left side cover has been removed
Incorrect replacement of the lithium battery may lead to a risk of
explosion.
The lithium battery must be replaced with an identical battery or with a
battery type recommended by the manufacturer (CR2032).
Do not throw lithium batteries into the trashcan. Please dispose of
batteries in accordance with local government regulations.
Make sure that you insert the battery the right way round. The plus pole
must be on the top!
Ê Push the locking spring in the direction of the arrow (1) so that the lithium
battery snaps out of the holder, and pull the battery out (2).
Ê Slide the new battery of identical type into the holder (3), and push it in the
direction of the arrow (4) until it locks in place.
If the batteries are not entirely empty and you replace them one after the
other (that means they are not removed at the same time), the settings
remain stored. Nevertheless check the date and the internal time after
replacing the two batteries.
