Important:
Each caution and danger statement in this document is labeled with a number. This
number is used to cross reference an English-language caution or danger
statement with translated versions of the caution or danger statement in the Safety
Information document.
For example, if a caution statement is labeled "Statement 1", translations for that
caution statement are in the Safety Information document under "Statement 1."
Be sure to read all caution and danger statements in this document before you
perform the procedures. Read any additional safety information that comes with the
server or optional device before you install the device.
Attention: The information in this document regarding installing and removing
power supplies and connecting and disconnecting power refers to ac power
supplies only. If the server contains dc power supplies, see the documentation that
comes with the dc power supplies. In a dc power environment, only trained service
personnel other than Lenovo service technicians are authorized to connect or
disconnect power to the dc power supply and to install and remove a dc power
supply.
