Classification of procedures
The complexity of procedures to install or replace hardware components varies 
a lot. Three categories indicate the degree of difficulty and the profile of 
qualification needed to perform a task. Warnings help you to assess the 
consequences for performing procedures without the required qualification.
At the beginning of each procedure, the category is indicated by the symbols 
introduced in this section. Please ask you local Fujitsu service center for more 
detailed information.
Trained personnel
Trained persons can install or replace certain hot-plug components 
during operation. The hot-plug procedure increases the availability of 
system operation and guarantees a high degree of data integrity and fail-
safe performance.
Components that can be handled by trained personnel are:
Power supply units, see 
Fan modules, see 
HDD modules and SSD modules, see 
Specialized personnel
Specialists can carry out certain expansions, upgrades, or replacements 
after the server has been shut down properly and powered off.

CAUTION!
The device can be seriously damaged if it is opened without
