6.1 Safety Precautions

For your protection, observe the following safety precautions when setting up your equipment:

Follow all cautions, warnings, and instructions marked on the equipment.
Ensure that the voltage and frequency rating of the power outlet you use matches the electrical rating label on the equipment and video monitor.
Only use properly grounded power outlets.
Never push objects of any kind through openings in the equipment as they may touch dangerous voltage points or short out components that could result in fire or electric shock.
Refer servicing of equipment to qualified personnel.

To protect both yourself and the equipment, observe the following precautions:

Table 6-1

Item	Problem	Precaution
Wrist or foot strap	ESD	Wear a conductive wrist strap or foot strap when handling printed circuit boards.
ESD mat	ESD	An approved ESD mat provides protection from static damage when used with a wrist strap or foot strap. The mat also cushions and protects small parts that are attached to printed circuit boards.
Cover panels	System damage and overheating	Re-install all cabinet cover panels after performing any service work on the system.
SBus slot covers	System damage and overheating	Install SBus slot covers in all unused SBus slots.

6.2 Symbols

WARNING	Hazardous voltages are present. To reduce the risk of electrical shock and danger to personal health, follow the instructions.
CAUTION	There is a risk of personal injury and equipment damage. Follow the instructions.
HOT SURFACE	CAUTION: Hot surfaces. Avoid contact. Surfaces are hot and may cause personal injury if touched.
AC	A terminal to which alternating current or voltage may be applied.

STANDBY

The key lock switch is in the STANDBY position.

Ensure that the voltage and frequency of the power outlet to be used matches the electrical rating labels on the cabinet.

Wear anti-static wrist straps when handling any magnetic storage devices or system boards.

Only use properly grounded power outlets as described in the SPARCcluster High Availability Server Hardware Planning and Installation.

Caution - DO NOT make mechanical or electrical modifications to the cabinet. Sun Microsystems is not responsible for regulatory compliance of modified cabinets.

Caution - Power off the equipment as directed in Chapter 7, "Shutdown and Restart Procedures," before performing any of the procedures described in this book.

Caution - Before servicing a power supply or power sequencer, ensure that the chassis AC power cord is removed from the AC wall socket. However, when servicing low voltage circuitry such as a system board, the AC power cord should remain plugged in to ensure proper grounding.

6.3 System Precautions

Warning - This equipment contains lethal voltages. Accidental contact can result in serious injury or death.

Caution - Improper handling by unqualified personnel can cause serious damage to this equipment. Unqualified personnel who tamper with this equipment may be held liable for any resulting damage to the equipment.

Persons who remove any of the outer panels to access this equipment must observe all safety precautions and ensure compliance with skill level requirements, certification, and all applicable local and national laws.

All procedures contained in this document must be performed by qualified service-trained maintenance providers.
