Precautions On Static Electricity - Oracle Fujitsu SPARC M12-1 Service Manual

Do not attempt to make any mechanical or electrical modifications. Fujitsu shall
■
not be responsible for the regulatory compliance of a SPARC M12-1 that has been
modified.
Rack-related safety precautions
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 rack from falling over when the SPARC
M12-1 slides out on slide rails, either for installation or maintenance.
Prior to installation or maintenance, a safety assessment should be conducted by
■
our service engineer in the following cases:
- When the quakeresistant options kit is not supplied and the rack is not fixed to
the floor with bolts: Confirm safety by checking whether the rack could fall over,
etc. when the SPARC M12-1 is pulled out on the slide rails.
- When the rack is to be installed on a raised floor: Confirm that the raised floor
can bear the load when the SPARC M12-1 is pulled out on the slide rails.
If the SPARC M12-1 is mounted at the 20U level or higher, use a step ladder.
■
If multiple SPARC M12-1 machines are mounted in a rack, perform maintenance
■
for each of them.
For details on the rack, see "Chapter 2 Planning and Preparing for System
Installation" in the Fujitsu SPARC M12-1 Installation Guide.

Precaution
Wear an antistatic wrist strap when handling printed boards and
components with electronic components mounted.
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.
