Safety Indications

vi Preface

Follow the instructions given in this service guide for proper operation and safe use of the NEC Express5800.

This guide describes server components with possible danger, hazards that may be caused by ignoring warnings, and preventive actions against such hazards.

Server components with possible danger are indicated with a warning label placed on or around them. They are also described in this guide.

In the user’s guide and on warning labels, “WARNING” or “CAUTION” is used to indicate a degree of danger. These terms are defined as follows:

	WARNING		Indicates the presence of a hazard that may cause loss of life or serious
	WARNING		personal injury if the instruction is ignored.
			personal injury if the instruction is ignored.
	CAUTION		Indicates the presence of a hazard that may cause minor personal injury,
	CAUTION		including burns or property damage, if the instruction is ignored.

Precautions and notices against hazards are presented with one of the following 3 symbols. The individual symbols are defined as follows:

This symbol indicates the presence of a hazard if the instruction is ignored. An image in the symbol illustrates the hazard type. (Attention)

This symbol indicates prohibited actions. An image in the symbol illustrates a particular prohibited action. (Prohibited Action)

This symbol indicates mandatory actions. An image in the symbol illustrates a mandatory action to avoid a particular hazard. (Mandatory Action)
