Notes:

1.The server does not support replaceable voltage regulator modules (VRMs).

2.The server supports a maximum of three PCI buses.

3.The server supports a maximum of three power supplies.

Light Path Diagnostics

You can use the light path diagnostics built into the server to quickly identify the type of system error that occurred. The server is designed so that LEDs remain illuminated when the server shuts down, as long as the power supplies are operating properly. This feature helps you to isolate the problem if an error causes the server to shut down.

If the system error LED (on the information LED panel) is not lit and no diagnostics panel LEDs are lit, it means that the light path diagnostics have not detected a system error.

If the system error LED (on the information LED panel) is lit, it means that a system error was detected. Check to see which of the LEDs on the diagnostics panel inside the server are lit and refer to the following table:

Table 1. Light Path Diagnostics

LED on

Cause

 

 

None

1. The system error log is 75% or more full or a PFA alert was logged. (See “Diagnostic panel error

 

 

LEDs” on page 101)

 

2. Bad, missing, or mis-installed processor terminator.

 

 

CPU

One of the microprocessors has failed. (See “Diagnostic panel error LEDs” on page 101)

 

 

Memory

A memory error occurred. (See “Diagnostic panel error LEDs” on page 101)

 

 

PCIA

An error occurred on PCI bus A. An adapter in PCI slot 1, or the system board, caused the error.

 

(See “Diagnostic panel error LEDs” on page 101)

 

 

PCIB

An error occurred on PCI bus B. An adapter in PCI slot 2, 3, or 4, or the system board, caused the

 

error. (See “Diagnostic panel error LEDs” on page 101)

 

 

PCIC

An error occurred on PCI bus C. An adapter in PCI slot 5 or 6, or the system board, caused the

 

error. (See “Diagnostic panel error LEDs” on page 101)

 

 

PCID

Not implemented at this time.

 

 

PS1

The first power supply has failed. (See “Diagnostic panel error LEDs” on page 101)

 

 

PS2

The second power supply has failed. (See “Diagnostic panel error LEDs” on page 101)

 

 

PS3

The third power supply has failed. (See “Diagnostic panel error LEDs” on page 101)

 

 

Fan

One of the fan assemblies has failed or is operating too slowly.

 

Note: A failing fan can also cause the TEMP and/or DASD LEDs to be on; see “Diagnostic panel

 

error LEDs” on page 101.

 

 

DASD

A hot-swap hard disk drive has failed on SCSI channel B (see “Diagnostic panel error LEDs” on

 

page 101).

 

 

NMI

A nonmaskable interrupt occurred. (The PCIA, PCIB, PCIC, or Memory LED will probably also be

 

on; see “Diagnostic panel error LEDs” on page 101.)

 

Note: The NMI LED can only be reset by completely removing power from system.

 

 

SP

The service processor has failed. (See “Diagnostic panel error LEDs” on page 101)

 

 

Event Log

Not implemented at this time.

 

 

Non Red

System is operating in non-redundant power mode. (See “Diagnostic panel error LEDs” on

 

page 101)
