CHAPTER 7 Protection Against Lightning
7.1

Protection of AC Line

The surge protection level of Fujitsu M10/SPARC Servers, SPARC Enterprise and
PRIMEQUEST power supply facility complies to the International Electrotechnical
Commission (IEC) standard. Therefore, special protective action against typical
multitude of lightning is not required. However, depending on the multitude of
induced surge energy, the equipment may be damaged by the induced surge.
Especially in some regions where often encounter thunder, implementation of
external surge absorber is recommended.
The preventive action on AC lines for surge attacks can be classified into following
three methods:

Using power control box (F9710PW2)
 Install a surge absorber in each terminal outlet
 Install a surge absorber to the input side of a distribution panel
The procedure for each method is described below.
(1) Using power control box (F9710PW2)
F9710PW2 power control box is effective for the components connected through
Switched/Unswitched type outlet. If power consumption sum of the components is
lower than 1.5 kVA, install the power control box between the processing components
and the power supply facility (connect the power cable of the processing component
with Unswitched outlet of the power control box). This control action protects the
processing components from surge voltage.
