x4500 or x4540 is running normally, however the system amber fault LED is illuminated. There are no other fault LEDs illuminated. There are no errors in the System Event Log (SEL) file to indicate what the problem is. This document explains the possible cause.

Details

The following information is taken from the combined Sun Fire x4500/x4540 Service Manual (819-4359-19).

The system may be in an unsupported configuration. Refer to the following four sections:

#1
Section 1.3.3 Rear Panel (X4500)

System Fault LED (amber)

Off--Normal operation

On--Service action is required.

A system running under these conditions are in a fault condition, but the SP does not log the reason the service LED is illuminated:

220VAC with only 1 PSU
110VAC with only two PSUs

#2
Section 3.3.3 Three-PSU 110V Option

The third power supply is not supported in x4500 systems and is only supported in X4540 systems originally manufactured with either of the following CPUs:

    Enhanced Quad-Core AMD Opteron Model 2384 (2.7 GHz, 75W ACP) (Shanghai) 2384 CPU (#371-4438)
    8000/2000 Series Six-core AMD Opteron Processor (Istanbul) 2435 (2.6 GHz, 75W ACP) (#371-1468)

Three PSUs are fully redundant at 110 VAC and provides resiliency against a power supply failure. If one power supply fails, the remaining two power supplies will continue to operate the system. Two PSUs does not provide power redundancy and is not supported.

To order the third PSU, you must first determine that the x4540 system is compatible with a third power supply (see conditions above), then order the following parts:

    X5037 (1300 W Power Supply for Sun Fire X4540 Storage Server)
    X311 or local equivalent (Power Cord Kit, North American/Asian)

Note - The third power supply is not supported in an older X4540 (#541-1218) or the Sun Fire X4500 system.

Note - When a system is configured for 3 PSUs at 100-120V AC and only 2 PSUs are installed, the amber System Fault LED LED illuminates.

Section C.1 Front Panel LEDs

System Fault LED

Amber

Off--Normal operation

On--Service action is required.

A system running under these conditions are in a fault condition, but the SP does not log the reason the service LED is illuminated:

Section C.1.1 Rear Panel LEDs

System Fault LED Amber

Off--Normal operation

On--Service action is required.

A system running under these conditions are in a fault condition, but the SP does not log the reason the service LED is illuminated:
