Description
Action
Memory
When only the Memory LED is
lit, a memory error has occurred.
Note:
Each time you install or remove a DIMM, you must
disconnect the server from the power source; then, wait 10
seconds before restarting the server.If the Configuration LED
is not lit, the system might detect a memory error. Complete
the following steps to correct the problem:
1.
Reseat or swap the DIMMs with lit LEDs.
2.
Check the system-event logs for information about the
error (see “Event logs” on page 144).
3.
Update the server firmware to the latest level (see
“Updating the firmware” on page 101 for more
information).
4.
Replace the failing DIMM (see “Installing a DIMM” on
page 300).
Configuration
When both the Memory and
Configuration LEDs are lit, the
memory configuration is invalid.
If the Memory LED and the Configuration LED are lit, check
the system-event logs for information about the error (see
“Event logs” on page 144).
Power supply
When only the Power supply
LED is lit, a power supply has
failed.
If the CONFIG LED is not lit, the system might detect a
power supply error. Complete the following steps to correct
the problem:
1.
Check the power-supply with an lit yellow LED (see
“Power-supply LEDs” on page 142).
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 voltage.
5.
Replace the failed power supply (see “Removing a
hot-swap power supply” on page 285).
Power Configuration
When both the Power supply
and Configuration 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.
Over spec
The power supplies are using
more power than their maximum
rating.
If the Over spec LED on the light path diagnostics panel is
lit, complete the following steps in order until the problem
is solved:
1.
Add a second power supply.
2.
Replace the failed power supply.
3.
Remove the optional devices.
