Notes Regarding Static Electricity - Fujitsu M10-4 Service Manual

Safety precautions on electricity
Confirm that the voltage and frequency of your input power supply match the
■
electric rating described on the system name plate label affixed on the chassis.
Wear a wrist strap when handling a hard disk drive, CPU memory unit, or other
■
printed boards.
Use grounded power outlets.
■
Do not attempt to make any mechanical or electrical modifications. Fujitsu shall
■
not be responsible for the regulatory compliance of a chassis that has been modified.
Safety precautions on the racks
The racks should be fixed on the floor, ceiling, or the adjacent frame.
■
The racks may be supplied with a quakeresistant options kit. The use of the
■
quakeresistant options kit prevents the racks from falling over during installation
or maintenance service on the chassis.
Prior to installation or maintenance, a safety assessment should be conducted by a
■
service engineer in the following cases:
■
If multiple chassis are mounted in a rack, perform maintenance for each of the
■
chassis.
For details of the racks, see "Chapter 2 Planning and Preparing for System
Installation" in the Fujitsu M10/SPARC M10 Systems Installation Guide.

Wrist strap
ESD mat
Antistatic bag/
ESD safe packaging box
When the quakeresistant options kit is not supplied and the rack is not fixed on
the floor with bolts: Check for the safety such as whether the rack should not
fall over.
to ensure the safety of personnel and the system.
Precaution
Wear an antistatic wrist strap when handling printed boards.
An approved ESD mat provides protection from static damage
when used with a wrist strap. The mat also acts as a cushion to
protect the small parts that are attached to printed boards.
After removing a printed board or component, place it in the
antistatic bag or ESD safe packaging box.
