xvi SPARC Enterprise M4000/M5000 Servers Service Manual • December 2010

Preface

This service manual describes how to service the SPARC Enterprise M4000/M5000
servers from Oracle and Fujitsu. This document is intended for authorized service
providers. References herein to the M4000 server or M5000 server are references to
the SPARC Enterprise M4000 or SPARC Enterprise M5000 server.

This document is written for maintenance providers who have received formal
service training. A single engineer service model is used for servicing SPARC
Enterprise M4000/M5000 midrange servers with one exception: When the
motherboard of a SPARC Enterprise M5000 server must be removed and that server
is mounted above waist high in the rack, then two engineers or a platform must be

This chapter describes safety and tools information. The information is organized
into the following topics:

■ Section 1.1, “Safety Precautions” on page 1-1

■ Section 1.2, “System Precautions” on page 1-2

1.1 Safety Precautions

To protect both yourself and the equipment, observe the following safety
precautions.

remove it.

1-1

Caution – Attach the cord of the antistatic wrist strap directly to the server. Do not

attach the antistatic wrist strap to the ESD mat connection.

The antistatic wrist strap and any components you remove must be at the same
potential.

1.2 System Precautions

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

■ Follow all cautions, warnings, and instructions marked on the equipment.

■ Never push objects of any kind through openings in the equipment, as they might

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

■ Refer servicing of equipment to qualified personnel.

1.2.1 Electrical Safety Precautions

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

Wear antistatic wrist straps when handling any magnetic storage devices,
system boards, or other printed circuit boards.

Use only properly grounded power outlets as described in the SPARC Enterprise
M4000/M5000 Servers Installation Guide.

Caution – Do not make mechanical or electrical modifications. The manufacturer is

not responsible for regulatory compliance of modified servers.

1.2.2 Equipment Rack Safety Precautions

All equipment racks should be anchored to the floor, ceiling, or to adjacent frames,
using the manufacturer’s instructions.

1-2 SPARC Enterprise M4000/M5000 Servers Service Manual • December 2010

Free-standing equipment racks should be supplied with a stabilizer feature, which
must be sufficient to support the weight of the server when extended on its slides.
This prevents instability during installation or service actions.

Where a stabilizer feature is not supplied and the equipment rack is not bolted to the
floor, a safety evaluation must be conducted by the installation or service engineer.
The safety evaluation determines stability when the server is extended on its slides,
prior to any installation or service activity.

Prior to installing the equipment rack on a raised floor, a safety evaluation must be
conducted by the installation or service engineer. The safety evaluation ensures that
the raised floor has sufficient strength to withstand the forces upon it when the
server is extended on its slides. The normal procedure in this case would be to fix the
rack through the raised floor to the concrete floor below, using a proprietary
mounting kit for the purpose.

Caution – If more than one server is installed in an equipment rack, service only one

server at a time.

1.2.3 Filler Boards and Filler Panels

Filler boards and panels, which are physically inserted into the server when a board
or module has been removed are used for EMI protection and for air flow.

1.2.4 Handling Components

Caution – There is a separate ground located on the rear of the server. It is

important to ensure that the server is properly grounded.

Caution – The server is sensitive to static electricity. To prevent damage to the

board, connect an antistatic wrist strap between you and the server.

Caution – The boards have surface-mount components that can be broken by flexing

the boards.

To minimize the amount of board flexing, observe the following precautions:

Chapter 1 Safety and Tools 1-3

■ Hold the board by the handle and finger hold panels, where the board stiffener is

located. Do not hold the board at the ends.

■ When removing the board from the packaging, keep the board vertical until you

lay it on the cushioned ESD mat.

■ Do not place the board on a hard surface. Use a cushioned antistatic mat. The

board connectors and components have very thin pins that bend easily.

■ Be careful of small component parts located on both sides of the board.

■ Do not use an oscilloscope probe on the components. The soldered pins are easily

damaged or shorted by the probe point.

■ Transport the board in its packaging box.

Caution – The heat sinks can be damaged by incorrect handling. Do not touch the

heat sinks while replacing or removing boards. If a heat sink is loose or broken,
obtain a replacement board. When storing or shipping a board, ensure that the heat
sinks have sufficient protection.

Caution – On the PCI cassette, when removing cables such as LAN cable, if your

finger can’t reach the latch lock of the connector, press the latch with a flathead
screwdriver to remove the cable. Forcing your finger into the clearance can cause
damage to the PCI card.

2.2 Checking the Server and System Configuration

Before and after maintenance work, the state and configuration of the server and
components should be checked and the information saved. For recovery from a
problem, conditions related to the problem and the repair status must be checked.
The operating conditions must remain the same before and after maintenance.

A functioning
For example:

■ The syslog file should not display error messages.

■ The XSCF Shell command showhardconf does not display the * mark.

■ The administrative console should not display error messages.

■ The server processor logs should not display any error messages.

■ The Oracle Solaris Operating System message files should not indicate any

additional errors.

server without any problems should not display any error conditions.

2.2.1 Checking the Hardware Configuration and FRU Status

To replace a faulty component and perform the maintenance on the server it is
important to check and understand the hardware configuration of the server and the
state of each hardware component.

The hardware configuration refers to information that indicates to which layer a
component belongs in the hardware configuration.

The status of each hardware component refers to information on the condition of the
standard or optional component in the server: temperature, power supply voltage,
CPU operating conditions, and other times.

2-4 SPARC Enterprise M4000/M5000 Servers Service Manual • December 2010

The hardware configuration and the status of each hardware component can be
checked from the maintenance terminal using eXtended System Control Facility
(XSCF) Shell commands, as shown in the following table.

TABLE 2-1 Commands for Checking Hardware Configuration

Command Description

showhardconf Displays hardware configuration.

showstatus Displays the status of a component. This command is used when

only a faulty component is checked.

showboards Displays the status of devices and resources.

showdcl Displays the hardware resource configuration information of a

domain.

showfru Displays the setting information of a device.

Also some conditions can be checked based on the On or blinking state of the
component LEDs (see

TABLE 2-3).

2.2.1.1 Checking the Hardware Configuration

Login authority is required to check the hardware configuration. The following
procedure for these checks can be made from the maintenance terminal:

1. Log in with the account of the XSCF hardware maintenance engineer.

2. Type showhardconf.

XSCF> showhardconf

The showhardconf command prints the hardware configuration information to

the screen. See the SPARC Enterprise M3000/M4000/M5000/M8000/M9000 Servers
XSCF User ’s Guide for more detailed information.

Chapter 2 Fault Isolation 2-5

2.2.2 Checking the Software and Firmware Configuration

The software and firmware configurations and versions affect the operation of the
server. To change the configuration or investigate a problem, check the latest
information and check for any problems in the software.

Software and firmware varies according to users:

■ The software configuration and version can be checked in the Oracle Solaris OS.

Refer to the Solaris 10 documentation for more information.

■ The firmware configuration and versions can be checked from the maintenance

terminal using XSCF Shell commands. Refer to the SPARC Enterprise
M3000/M4000/M5000/M8000/M9000 Servers XSCF User’s Guide for more detailed

information.

Check the software and firmware configuration information with assistance from the
system administrator. However, if you have received login authority from the system
administrator, the commands shown in the table can be used from the maintenance
terminal for these checks.

TABLE 2-2 Commands for Checking Software and Firmware Configuration

Command Description

showrev(1M) System administration command that displays information system

patches.

uname(1) System administration command that outputs the current system

information.

version(8) XSCF Shell command that outputs the current firmware version

information.

showhardconf(8) XSCF Shell command that indicates information on components

mounted on the server.
