• Read “Installation Guidelines” on page 41 and “Safety inspection checklist” on page 42 to make sure that
you work safely.
• Make sure to read the following notes carefully before replacing the CMOS battery in the node.
– Do not make CMOS battery in contact with any metal surface during the replacement. Any contact with
a metal surface, such as the node and chassis side, can cause damages to the battery.
– When replacing the battery, you must replace it with another CMOS battery of the exact same type
(CR2032) made by the same manufacturer.
– After replacing the battery, make sure to reconfigure the node and reset the system date and time.
– Dispose of the battery as required by local ordinances or regulations.
Procedure
Step 1. Make preparations for this task.
a. Power off the node (see
“Power off the node” on page 51); then, disconnect all external cables
from the node.
b. Remove the node from the chassis (see
“Remove a node from the chassis” on page 72); then,
carefully lay the node on a flat, static-protective surface, orienting the node with the front
toward you.
Notes:
• When removing the node, note the node tray number and make sure to install the node in
the same tray from which it was removed. Reinstalling the node into a different tray requires
the node to be reconfigured.
• For safety, make sure to hold the node with both hands when lifting the node.
c. Remove the top cover (see
“Remove the top cover” on page 168).
d. Disconnect all the cables from the drive backplane; then, remove the drive cage assembly from
the node and place it on a flat, static-protective surface (see
“Remove the drive cage
assembly” on page 84
).
e. Locate the CMOS battery socket on the system board.

Step 2. Remove the CMOS battery from the node.
a.
Gently push the battery socket clip backward to release the CMOS battery.
b.
Carefully take the battery out of the socket.
