Troubleshooting
Problem
Diagnosing the status LEDs for the IBM Netfinity 5600 (Type 8664) server.
Resolving The Problem
This index supports Netfinity 5600 - Type 8664 servers.
| Notes: 1. Check the configuration before you replace a FRU. Configuration problems can cause false errors and symptoms. 2. For IBM devices not supported by index, refer to the manual for that device. 3. Always start with "General checkout". |
The Symptom-to-FRU lists symptoms, errors, and the possible causes. The most likely cause is listed first. Use this Symptom-to-FRU Index to help you decide which FRUs to have available when servicing the computer.
Status LEDs
Your server has LEDs to help you identify problems with some server components. These LEDs are part of the light path diagnostics built into the server. By following the path of lights, you can quickly identify the type of system error that occurred. See "Light path diagnostics" for more information.
Status LEDs are located on the information panel.
For more information, see "Operator information panel" (hard disk drive trays).
For more information, see "Controls and indicators" (power supply).
For more information, see "Power supply LEDs" (diagnostics panel).
For more information, see "Diagnostics panel LEDs" (system board).
See "System board component locations" for locations of the LEDs on the system board (processor board).
See "Processor board component locations" for locations of the LEDs on the processor board.Power supply LEDs
The AC and DC Power LEDs on the power supply provide status information about the power supply. See "Power supplies" for the location of these LEDs.
The following table describes the AC and DC Power LEDs.
| AC Power LED | DC Power LED | Description and action |
|---|---|---|
| On | On | The power supply is on and operating correctly. |
| On | Off | There is a DC power problem. Possible causes: 1. The Power Control button on the front of the server is in the Off position. Action: Press the Power Control button to start the server. 2. The power supply has failed. Action: Replace the power supply. |
| Off | Off | There is an AC power problem. Possible causes: 1. There is no AC power to the power supply. Action: Verify that:
2. The power supply has failed. Action: Replace the power supply. If the problem persists, go to "Undetermined problems". |
Diagnostics panel LEDs
The following illustration shows the LEDs on the diagnostics panel inside the server. See "Light path diagnostics" for information on identifying problems using these LEDs.
