After you remove the CMOS battery, dispose of the CMOS battery as required by local ordinances or
regulations.
Installing the CMOS battery
Use this information to install a CMOS battery.
Before you install the CMOS battery, complete the following steps:
1. Read “Safety” on page iii and “Installation guidelines” on page 637.
2. If the compute node is installed in an Flex System chassis, remove it (see “Removing a compute node
from a chassis” on page 639 for instructions).
3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with
the bezel pointing toward you.
The following notes describe information that you must consider when you replace 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 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 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.
To install a CMOS battery, complete the following steps:
Step 1. Remove the cover (see “Removing the compute node cover” on page 643).
Step 2. Follow any special handling and installation instructions that come with the CMOS battery.
