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 those
■
shown on the electric rating 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.

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.
