Use this information to install a CMOS battery.
Before you begin
Before you install the CMOS battery, complete the following steps:
- Read Safety and Installation guidelines.
- If the compute node is installed in a chassis, remove it (see Removing a compute node from a chassis for instructions).
- Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the bezel pointing toward you.
About this task
The following notes describe information that you must
consider when you are replacing the CMOS battery in the compute node:
- You must replace the CMOS battery with a lithium CMOS battery of the same type.
- To order replacement batteries, call 1-800-426-7378 within the United States, and 1-800-465-7999 or 1-800-465-6666 within Canada. Outside the U.S. and Canada, call your IBM marketing representative or authorized reseller.
- After you replace the CMOS battery, you must reconfigure the compute node and reset the system date and time.
- To avoid possible danger, read and follow the following safety statement.
Statement 2
CAUTION:
When
replacing the lithium battery, use only IBM Part
Number 33F8354 or an equivalent type battery recommended by the manufacturer.
If your system has a module containing a lithium battery, replace
it only with the same module type made by the same manufacturer. The
battery contains lithium and can explode if not properly used, handled,
or disposed of.
Do not:
- Throw or immerse into water
- Heat to more than 100° C (212° F)
- Repair or disassemble
Dispose of the battery as required by local ordinances or regulations.
Attention: Touching the CMOS
battery on a metal surface, such as the side of the compute node,
when you replace the CMOS battery can cause it to fail.
Procedure
To install a CMOS battery, complete the following steps:
- Remove the cover (see Removing the compute node cover).
- Follow any special handling and installation instructions that come with the CMOS battery.
- Locate the CMOS battery socket on the system board (see System-board connectors).
-
Orient the CMOS battery so that the positive (+) side faces
in toward the center of the compute node.
- Pivot the CMOS battery so that you can insert it into the bottom of the socket.
- As you slide the CMOS battery into place, press the top of the CMOS battery into the socket.
- If you removed a cover from the battery, replace the cover.
What to do next
After you install the
CMOS battery, complete the following
steps:
- Install the cover onto the compute node (see Installing the compute node cover for instructions).
- Install the compute node into the chassis (see Installing a compute node in a chassis for instructions).
- Turn on the compute node, start the Setup utility, and reset the configuration (see Using the Setup utility for instructions).
