Identifying Problems Using Status LEDs
Identifying Problems Using Status LEDs
Your Netfinity 5000 server has LEDs to help you identify problems with some server components. These LEDs are part of the diagnostics built into the Netfinity
5000 server. By following the path of lights, you can quickly identify the type of system error that occurred.
Status LEDs are located on the following components:
Operator LED panel
For more information, see “Status Indicators” on page 9.
Hard disk drive trays
For more information, see “Server Controls” on page 7.
Power supply
For more information, see “Power Supply LEDs.”
System board
See “System Board LEDs” on page 168 for locations of the LEDs on the system board.
Power Supply LEDs
The AC Power LEDs on the power supply provide status information about the power supply. See “Status Indicators” on page 9 for the location of these LEDs.
The following table describes the AC Power LEDs.
AC Power LED
On
Off
Description and Action
The power supply is on and operating correctly.
There is an AC power problem.
Possible causes:
1. There is no AC power to the power supply.
Actions: Verify that:
The power cord is properly connected to the Netfinity
5000 server.
The power outlet functions properly.
2. The power supply has failed.
Action: Replace the power supply.
If the problem persists, have the system serviced.

Identifying Problems Using Status LEDs
LED Diagnostics
The diagnostics built into your Netfinity 5000 server allow you to quickly identify the type of system error that occurred. When the System Error LED on the information
LED panel is illuminated, use the following information to isolate the problem. An error message usually appears on the display monitor as well.
If the System Error LED on the information LED panel on the front of the
Netfinity 5000 server is on, a system error was detected. Check the LEDs on the power supplies and at any Ethernet adapters, then open the cover and check to see which of the LEDs on the system board inside the Netfinity 5000 server are on. (See “System Board LEDs” on page 168 for the location of the
LEDs.)

PCI 1 LED on
PCI 2 LED on
DIMM 1 Error LED on
DIMM 2 Error LED on
DIMM 3 Error LED on
DIMM 4 Error LED on
Description
An error has occurred in the service processor.
Actions: If the problem persists, have the system serviced.
A non-maskable interrupt occurred. The PCI 1 or PCI 2 LED will probably also be on.
Actions:
1. If the PCI 1 or PCI 2 LED is on, follow the instructions for those LEDs.
2. If the PCI 1 or PCI 2 LED is not on, restart the
Netfinity 5000 server. If the problem persists (the
NMI LED stays on), have the system serviced.
A system-management interrupt occurred. This is an indication of service processor activity, and is not an error.
Actions: No action is required.
An error occurred on PCI bus 0. An adapter in PCI slot 5 or the system board caused the error.
Actions: Check the error log for additional information. If the error log indicates a problem with the integrated
Ethernet controller, have your system serviced.
If the problem persists, have the system serviced.
An error occurred on PCI Bus 1. An adapter in PCI slot 1, 2, 3, or 4 or the system board caused the error.
Actions:
1. Check the error log for additional information.
2. If you cannot correct the problem from the information in the error log, try to determine the failing adapter by removing one adapter at a time from the secondary PCI bus (PCI slots 1–4) and restarting the Netfinity 5000 server after each adapter is removed.
If the problem persists, have the system serviced.
The DIMM in DIMM slot 1 has failed.
Action: Replace the DIMM in DIMM slot 1.
The DIMM in DIMM slot 2 has failed.
Action: Replace the DIMM in DIMM slot 2.
The DIMM in DIMM slot 3 has failed.
Action: Replace the DIMM in DIMM slot 3.
The DIMM in DIMM slot 4 has failed.
Action: Replace the DIMM in DIMM slot 4.

Description
Fan 1 has failed or is operating too slowly.
Note: A failing fan can also cause the TEMP and DASD 1
LEDs to be on.
Action: Replace fan 1.
Fan 2 has failed or is operating too slowly.
Note: A failing fan can also cause the TEMP and DASD 1
LEDs to be on.
Action: Replace fan 2.
The system temperature has exceeded the maximum rating.
Actions:
1. Check to see if a fan has failed. If it has, replace the fan.
2. Make sure the room temperature is not too hot.
(See Table 11 on page 95)
If the problem persists, have the system serviced.
The voltage regulator for the primary microprocessor slot has failed.
Actions: Have the system serviced.
The voltage regulator module (VRM) for the secondary microprocessor slot has failed.
Actions:
1. Turn off the Netfinity 5000 server, reseat the VRM, and restart the Netfinity 5000 server.
2. If the problem persists, replace the VRM.
If the problem persists, have the system serviced.
The microprocessor in the primary microprocessor slot has failed.
Actions:
1. Turn off the Netfinity 5000 server, reseat the VRM, and restart the Netfinity 5000 server. and restart the
Netfinity 5000 server.
2. If the problem persists, replace the microprocessor.
If the problem persists, have the system serviced.
The microprocessor in the secondary microprocessor slot has failed.
Actions:
1. Turn off the Netfinity 5000 server, reseat the microprocessor, and restart the Netfinity 5000 server.
2. If the problem persists, replace the microprocessor.
If the problem persists, have the system serviced.
The primary power supply has failed.
Action: Have the primary power supply replaced.
The secondary power supply has failed.
Action: Replace the secondary power supply.

Description
A hot-swap hard disk drive has failed.
Actions:
1. Check the error log for additional information. If the error log indicates a temperature problem and the fans are working correctly, have the system serviced.
2. If the amber Hard Disk Status LED on one of the hot-swap hard disk drives is on, replace the hard disk drive.
System Error LED on the information LED panel on the front of the Netfinity
5000 server is off. The diagnostics have not detected a system error.
