Table 12. Light path diagnostics panel LEDs (continued)
LED Description Action
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 137).
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 243).
Power supply
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
OVER
S P EC
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.
PCI An error has occurred on a PCI
card or a PCI bus. 1. Check if any PCI slot error LED is lit to identify the
component that caused the error.
2. Check the system-error log for information about the
error (see “Event logs” on page 139).
3. If you cannot isolate the failing component by using
the LEDs and the information in the system-event
logs, remove one component at a time; and restart
the server after each component is removed.
4. If the failure remains, go to
http://www.lenovo.com/support.
NMI A nonmaskable interrupt has
occurred, or the NMI button
was pressed.
1. Check the system-event logs for information about
the error (see “Event logs” on page 139).
2. Restart the server.
System board An error has occurred on
the system battery, the
microprocessor 2 expansion
board, the power paddle card,
or the system board. 1. Check the LEDs on the system board to identify the
component that caused the error. The System board
LED can be lit due to any of the following reasons:
• Battery (see “Removing the system battery” on
page 227 and “Installing the system battery” on
page 228).
• Power paddle card (see “Removing the power
paddle card” on page 265 and “Installing the
power paddle card” on page 267).
