Netfinity 5500 M10 - Light Path Diagnostics
Applicable to: World-Wide
Light Path Diagnostics
The light path diagnostics built into your server allow you to quickly identify the type of system error that occurred. Your server is designed so that any LEDs that are illuminated remain illuminated when the server shuts down as long as the AC power source is good and the power supplies can supply +5V current to the server. This feature helps you isolate the problem if an error causes the server to shut down.
The light path diagnostics begins with the System Error LED on the information LED panel. (See the illustration in "Information LED Panel".) When this light is illuminated, use the following information to isolate the problem.
If the System Error LED on the information LED panel on the front of the server is on, a system error was detected. Check to see which of the LEDs on the diagnostics panel inside the server are on.
SMI LED on
A systems management event occurred.
Action: Restart the server. If the problem persists, go to "General Checkout".
NMI LED on
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 server. If the problem persists, go to "General Checkout".
PCI 1 LED on
An error occurred on the primary PCI channel.
An adapter in PCI slot 5 or 6 or the system board caused the error.
Actions:
1. Check the error log for additional information. If the error log indicates a problem with the integrated ServeRAID controller or the Ethernet controller, go to "General Checkout".
2. If you cannot isolate the failing adapter from the information in the error log, try to determine the failing adapter by removing one adapter at a time from the primary PCI bus (PCI slots 5 and 6) and restarting the server after each adapter is removed.
If the problem persists, go to "General Checkout".
PCI 2 LED on
An error occurred on the secondary PCI channel. 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 server after each adapter is removed.
If the problem persists, go to "General Checkout".
MEM LED on
A memory error occurred. Check the DIMM Error LEDs on the processor board.
- DIMM 1 Error LED on
The DIMM in DIMM slot 1 has failed.
Action: Replace the DIMM in DIMM slot 1.
- DIMM 2 Error LED on
The DIMM in DIMM slot 2 has failed.
Action: Replace the DIMM in DIMM slot 2.
- DIMM 3 Error LED on
The DIMM in DIMM slot 3 has failed.
Action: Replace the DIMM in DIMM slot 3.
- DIMM 4 Error LED on
The DIMM in DIMM slot 4 has failed.
Action: Replace the DIMM in DIMM slot 4.
FAN 1 LED on
Fan 1 has failed or is operating too slowly.
Note: A failing fan can also cause the TEMP and DASD1 LEDs to be on.
Action: Replace fan 1.
FAN 2 LED on
Fan 2 has failed or is operating too slowly.
Note: A failing fan can also cause the TEMP and DASD1 LEDs to be on.
Action: Replace fan 2.
FAN 3 LED on
Fan 3 has failed or is operating too slowly.
Note: A failing fan can also cause the TEMP and DASD1 LEDs to be on.
Action: Replace fan 3.
TEMP LED on
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 "Specifications"). If the problem persists, go to "General Checkout".
VRM LED on
One of the voltage regulator modules on the processor board has failed. Check the VRM Error LEDs on the processor board.
- Primary Processor Cache VRM Error LED on
The cache VRM for the primary microprocessor slot has failed.
Actions:
1. Turn off the server, reseat the VRM, and restart the server.
2. If the problem persists, replace the VRM. If the problem persists, go to "General Checkout".
- Primary Processor Core VRM Error LED on
The core VRM for the primary microprocessor slot has failed.
Actions:
1. Turn off the server, reseat the VRM, and restart the server.
2. If the problem persists, replace the VRM. If the problem persists, go to "General Checkout".
- Secondary Processor Cache VRM Error LED on
The cache VRM for the secondary microprocessor slot has failed.
Actions:
1. Turn off the server, reseat the VRM, and restart the server.
2. If the problem persists, replace the VRM. If the problem persists, go to "General Checkout".
- Secondary Processor Core VRM Error LED on
The core VRM for the primary microprocessor slot has failed.
Actions:
1. Turn off the server, reseat the VRM, and restart the server.
2. If the problem persists, replace the VRM. If the problem persists, go to "General Checkout".
CPU LED on
One of the microprocessors has failed. Check the Microprocessor Error LEDs on the processor board.
- Primary Microprocessor Error LED on
The microprocessor in the primary microprocessor slot has failed.
Actions:
1. Turn off the server, reseat the microprocessor, and restart the server.
2. If the problem persists, replace the microprocessor. If the problem persists, go to "General Checkout".
- Secondary Microprocessor Error LED on
The microprocessor in the secondary microprocessor slot has failed.
Actions:
1. Turn off the server, reseat the microprocessor, and restart the server.
2. If the problem persists, replace the microprocessor. If the problem persists, go to "General Checkout".
PS1 LED on
The primary power supply has failed.
Action: Replace the primary power supply.
PS2 LED on
The secondary power supply has failed.
Action: Replace the secondary power supply.
DASD 1 LED on
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, go to "General Checkout".
2. If the amber Hard Disk Status LED on one of the hot-swap hard disk drives is on, refer to the "ServeRAID Information" section of this Server Library for more information.
System Error LED on the information LED panel on the front of the server is off. The light path diagnostics have not detected a system error.
