BeforeYouStart

This manual provides procedures for installing a power supply in a redundantcapable SPARCcenter 2000 or 2000E system cabinet.

1.1 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

• Use properly grounded power outlets only.

• Never push objects of any kind through openings in the equipment as they

• Refer servicing of equipment to qualified personnel.

matches the electrical rating label on the equipment and video monitor.

may touch dangerous voltage points or short out components that could result in fire or electric shock.

1-1

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

Table 1-1 Safety Precautions

Item Problem Precaution

Springfingers Personal injury The springfingers have sharp edges. Use care when handling springfinger-

equipped cabinet screens and system boards.

RFI leakage Keep springfinger-equipped screens and panels in place when the system is

running. These assemblies suppress radio frequency interference (RFI) and are required by law in many localities.

Damaged springfingers

Wrist strap or Foot strap

ESD mat ESD An approved ESD mat provides protection from static damage when used

Cover panels System damage

Filler panels System damage

SBus slot covers System damage

ESD Wear a conductive wrist strap or foot strap when handling printed circuit

and overheating

Look for any broken or twisted springfingers and replace any damaged screen or board with a new assembly.

boards.

with a wrist strap or foot strap. The mat also cushions and protects small parts that are attached to printed circuit boards.

Attach all cabinet cover panels after performing service work on the system.

Install card cage filler panels in all unused card cage slots. Open slots severely reduce the cooling capability of the system.

Install SBus slot covers in all unused system board SBus slots. Openings on the backs of system boards reduce the cooling capability of the system.

1.2 Symbols

The following symbols mean:

WARNING Risk of electrical shock.To reduce

the risk, follow the instructions.

WARNING Risk of personal injury. To reduce the

risk, follow the instructions.

1-2 SPARCserver 2000E Power Supply Installation Manual—April 1995

CAUTION Risk of equipment damage. To reduce

the risk, follow the instructions.

AC A terminal to which alternating

current or voltage may be applied.

ON The principal and stand-by switches

are in the ON position.

OFF The principal switch is in the OFF

position.

STAND-BY The stand-by switch is in the

STAND-BY position.

PROTECTIVE EARTH Protective earth conductor.

CHASSIS Frame or chassis terminal.

FUSE REPLACEMENT For continued protection against risk

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 cabinet and all equipment connected to it before performing any of the procedures described in this book. The system chassis power must be turned off, and the AC power cord must remain plugged in to ensure a proper ground.

BeforeYouStart 1-3

MARKING of fire and electric shock, replace

ONLY with same type and rating of fuse.

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.

Caution – Before you begin, carefully read each of the procedures in this manual. If you have not performed similar operations on comparable equipment, do not attempt to perform these procedures.

1.3 Tools Required

The following list represents the minimum of tools and test equipment required to service the system cabinet:

• Screwdriver, slotted, 3/16 inch

• Screwdriver, Phillips #2

• Screwdriver, Phillips #1

• Hex driver, M-4

• Hex driver, 3/16 inch

• Hex driver, 9 mm
