4. Remove the battery:
a. Use one finger to slightly slide the battery toward the front of the server.
(The spring mechanism behind the battery pushes it out toward you as you
slide it forward.)
b. Use your thumb and index finger to hold the battery as it pushes out of the
socket.
5. Insert the new battery:
a. Tilt the battery so that you can insert it into the front of the socket.
b. As you slide it toward the front of the server, push it down into the socket.
6. Reconfigure your system and reset the system date and time. If you are running
AIX the bootlist command may have to be run from AIX while logged in as root,
this restores the custom boot list and allow the option of Select Software under
multiboot to start the operating system. Other parameters that may have to be
rebuilt are the IP parameters.
7. Replace the covers as described in “Replacing Both the Front and Side Covers”
on page 5-96.
