1.2 Basic Troubleshooting

In a functioning Sun Fire E2900 system without any known problems, the system
should not display any error conditions. For example:

■ System fault LED should not be lit.

■ Fault LEDs on all field-replaceable units (FRUs) should not be lit.

■ syslog file should not display error messages.

■ Administrative console should not display error messages.

■ System controller logs should not display any error messages. See the

Troubleshooting chapter of the system administration manual for more
information.

■ Solaris Operating System (Solaris OS) message files should not indicate any

additional errors. See the Troubleshooting chapter of the system administration
manual for this product for more information on the various message files.

If a problem or failure occurs, the system controller does the following:

■ Attempts to determine what hardware is faulty

■ Takes steps to prevent that hardware from being used until it has been replaced

Some of the specific actions the system controller takes include:

■ May cause the hardware to pause while software analyzes and records the event

error

■ Determines whether or not the error is recoverable and if the system needs to be

reset

■ When possible, causes the faulty FRU to provide an LED indication of a fault in

addition to populating the system console messages with further details

■ Determines if dynamic deconfiguration and reconfiguration is applicable

If the system cannot diagnose the problem, see the following sections for
troubleshooting information.

Chapter 1 Fault Isolation 1-5

1.2.1 Power Distribution

To troubleshoot the power distribution system, do the following:

1. Ensure that all cabling is properly connected.

2. Check that switch positions are correct on all involved FRUs.

3. Check that the LEDs on the involved FRUs are as indicated in the following
sections.

1.2.1.1 Normal Operation

The LED status of all FRUs in a properly operating Sun Fire system is described in

TABLE 1-2.

1.2.1.2 Abnormal Operation

When an abnormal condition of faulty incoming power exists, the amber fault LED
( ) is lit on one or more of the involved FRUs.

1-6 Sun Fire E2900 System Service Manual • May 2006

1.2.2 Main Fans

The system has a fan tray assembly that cools all components in the system. There
are eight hot-swappable main fans in the fan tray. To determine if a fan in the fan
tray is faulty:

1. Inspect the fan LEDs. Determine if one or more fault LEDs ( ) on each fan is
lit, which means there is an internal fault or failure.

See Section 1.4.1, “Interpreting LEDs” on page 1-9 and
If a fan in the fan tray is faulty, the system controller changes the fan speed of the

remaining working fans to high speed to compensate for reduced air flow.

2. Replace the faulty fan. The fans are hot-swappable.

See Section 7.1.2, “Removing a Main Fan” on page 7-4 and Section 7.1.3, “Installing a

Main Fan” on page 7-6.

1.2.3 System Controller

The system controller receives error messages from each of the boards and
determines the appropriate actions to take. Typical actions include:

■ Setting the appropriate error status bits

■ Asserting error pause to stop further address packets

■ Interrupting the system controller

2.3 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 installation guide.

Caution – Do not make mechanical or electrical modifications. Sun Microsystems™

is not responsible for regulatory compliance of modified systems.

Caution – The chassis AC power cords must remain connected to ensure a proper

ground.

2.4 System Cabinet Safety Precautions

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

Free-standing cabinets should be supplied with an anti-tilt feature, which must be
extended to a minimum of 10.6 inches (27 cm) from the front edge of the rack, or at
least sufficiently to support the weight of the system when extended on its slides.
This prevents instability during installation or service actions.

Where an anti-tilt feature is not supplied and the system cabinet is not bolted to the
floor, a safety evaluation must be conducted by the installation or service engineer.
The safety evaluation determines the cabinet stability when the system is extended
on its slides, prior to any installation or service activity.

Prior to installing the system cabinet 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
system is extended on its slides. The normal procedure in this case would be to fix
the system cabinet through the raised floor to the concrete floor below, using a
proprietary rackmounting kit for the purpose.

2-4 Sun Fire E2900 System Service Manual • May 2006

Caution – If more than one system is installed in a system cabinet, service only one

system at a time.

2.5 Handling Boards and Assemblies

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

important to ensure that the system is properly grounded.

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

!

!

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

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:

■ Hold the board only by the handle and by the green fingerhold panels, where the

board stiffener is located. Do not hold the board only 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 heatsinks can be damaged by incorrect handling. Do not touch the

!

!

heatsinks while replacing or removing boards. If a heatsink is loose or broken, obtain
a replacement board.

Caution – The heatsinks can be damaged by improper packaging. When storing or

shipping a board, ensure that the heatsinks have sufficient protection.
