Before reading this manual
For your safety
This manual contains important information for safely and correctly using this
product.
Carefully read the manual before using this product. Pay particular attention to
the accompanying manual "Safety Notes and Regulations" and ensure these
safety notes are understood before using the product. Keep this manual and the
manual "Safety Notes and Regulations" in a safe place for easy reference while
using this product.
Radio interference
This product is a "Class A" ITE (Information Technology Equipment). In a
domestic environment this product may cause radio interference, in which case
the user may be required to take appropriate measures. VCCI-A
Aluminum electrolytic capacitors
The aluminum electrolytic capacitors used in the product's printed circuit board
assemblies and in the mouse and keyboard are limited-life components. Use of
these components beyond their operating life may result in electrolyte leakage
or depletion, potentially causing emission of foul odor or smoke.
As a guideline, in a normal office environment (25°C) operating life is not
expected to be reached within the maintenance support period (5 years).
However, operating life may be reached more quickly if, for example, the
product is used in a hot environment. The customer shall bear the cost of
replacing replaceable components which have exceeded their operating life.
Note that these are only guidelines, and do not constitute a guarantee of
trouble-free operation during the maintenance support period.
High safety use
This product has been designed and manufactured to be used in commercial
and/or industrial areas as a server.
When used as visual display workplace, it must not be placed in the direct field
of view to avoid incommoding reflections (applies only to TX server systems).
The device has not been designed or manufactured for uses which demand an
extremely high level of safety and carry a direct and serious risk of life or body
if such safety cannot be assured.

Upgrade and Maintenance Manual RX2540 M2
These uses include control of nuclear reactions in nuclear power plants,
automatic airplane flight control, air traffic control, traffic control in mass
transport systems, medical devices for life support, and missile guidance
control in weapons systems (hereafter, "high safety use"). Customers should
not use this product for high safety use unless measures are in place for
ensuring the level of safety demanded of such use. Please consult the sales
staff of Fujitsu if intending to use this product for high safety use.
Measures against momentary voltage drop
This product may be affected by a momentary voltage drop in the power supply
caused by lightning. To prevent a momentary voltage drop, use of an AC
uninterruptible power supply is recommended.
(This notice follows the guidelines of Voltage Dip Immunity of Personal
Computer issued by JEITA, the Japan Electronics and Information Technology
Industries Association.)
