System-error
LED
An error has 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 afterwards.
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 (see
“Power-supply LEDs” on page 135).
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 server
are of the same AC input voltage.
5. Replace the failed power supply (see “Removing a
hot-swap ac power supply” on page 259 and “Installing a
hot-swap ac power supply” on page 259).
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 server are of the same rating
or wattage.
