Installing or Replacing Server Components 77
9 Close the card retainer on the back panel and tighten its thumbscrew.
10 Close the server and reconnect all cords and cables.
Replacing the Battery
The server has a 3.6 V lithium battery installed on the main logic board. Some signs that you
need to replace the battery are intermittent problems starting up the computer and random
changes in its date and time settings. You can purchase a replacement battery from the
dealer where you bought your server.
Follow these steps to replace the lithium battery.
1 Shut down the server.
Be sure to alert users that the server will be unavailable for a period of time.
2 Disconnect the power cord from the back panel of the server. (If the cable-management arm
is not attached, you will also have to disconnect cables from the back panel.)
Swing the small metal plate
to its closed position, and
tighten the thumbscrew.
Warning If you removed a card from the server and did not install a replacement, be
sure to place a port access cover over the empty slot in the back panel. Do not leave an
empty slot without a cover. An uncovered slot can affect the airflow that cools the server’s
internal components and cause damage.
Warning
There is a risk of explosion if the incorrect type of battery is installed.
Warning The only way to shut off power completely is to unplug the power cord. Make
sure that the cord is disconnected before removing or installing any components inside
the server.
