4. Check the Light path diagnostics LEDs for the correct combination of power
LEDs that should be displayed during typical operation.
Light path diagnostics LEDs
LEDs on the light path diagnostics panel of the file module indicate the cause of a
problem. The topic describes the suggested actions to correct the detected
problems.
Table 43. LED indicators, corresponding problem causes, and corrective actions
v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v If an action step is preceded by "(Trained technician only)," that step must be completed only by a trained
technician.
LED Problem Action
Check log LED An error occurred and cannot be
isolated without completing
certain procedures.
1. Check the IMM2 system event log and the system-error
log for information about the error.
2. Save the log if necessary and clear the log afterward.
System-error
LED
An error occurred.
1. Check the light path diagnostics LEDs and follow the
instructions.
2. Check the IMM2 system event log and the system-error
log for information about the error.
3. Save the log if necessary and clear the log afterward.
PS When only the PS LED is lit, a
power supply has failed.
The system might detect a power supply error. Complete the
following steps to correct the problem:
1. Check the power-supply with a lit yellow LED.
2. Make sure that the power supplies are seated correctly
and plugged in a good AC outlet.
3. Remove one of the power supplies to isolate the failed
power supply.
4. Make sure that both power supplies installed in the file
module are of the same AC input voltage.
5. Replace the failed power supply.
PS + CONFIG
When both the PS and CONFIG
LEDs are lit, the power supply
configuration is invalid.
If the PS LED and the CONFIG LED are lit, the system issues
an invalid power configuration error. Make sure that both
power supplies installed in the file module are of the same
rating or wattage.
OVER SPEC The system consumption reaches
the power supply over current
protection point or the power
supplies are damaged.
1. If the Power Rail (A, B, C, D, E, F, G, and H) error was
not detected, complete the following steps:
a. Use the IBM Power Configurator utility to determine
current system power consumption. For more
information and to download the utility, go to
http://www-03.ibm.com/systems/bladecenter/
resources/powerconfig.html.
b. Replace the failed power supply.
2. If the Power Rail (A, B, C, D, E, F, G, and H) error was
also detected, follow actions in the "Power problems"
under the Troubleshooting tables and "Solving power
problems" in the Problem Determination and Service Guide.
