Safety precautions on electricity

■Confirmthat the voltage and frequency of your input power supply match those
shown on the electric rating label affixed on the chassis.
■Weara wrist strap when handling a hard disk drive, CPU memory unit, or other
printedboards.
■Usegro unded power outlets.
■Do not attemptto mak eany mech anical or electrical modifications. Fujitsu shall
not be responsible for the regulatory compliance of a chassis that has been modified.

Safety precautions on the racks

■Ther acks should be fixed on the floor, ceiling, or the adjacent frame.
■Ther acks 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
serviceen gineer in the following cases:
■When the quakeresistant options kit is not supplied and the rack is not fixed on
thefloor with bolts: Check for the safety such as whether the rack should not
fallover.
■Ifmultiple chassis are mounted in a rack, perform maintenance for each of the
chassis.
Fordetails of the racks, see "Chapter 2 Planning and Preparing for System
Installation" in the Fujitsu M10/SPARCM10 Systems Installation Guide.
