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 performed only by a trained
technician.
LED Description Action
OVER SPEC The system consumption reaches
the power supply over-current
protection point or the power
supplies are damaged.
1. If the Pwr 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 (see “Installing a
hot-swap ac power supply” on page 115).
2. If the Pwr 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.
PCI An error has occurred on a PCI
card, a PCI bus, or on the system
board. An additional LED is lit
next to a failing PCI slot.
1. If the CONFIG LED is not lit, complete the following steps
to correct the problem:
a. Check the riser-card LEDs, the ServeRAID error LED,
and the optional network adapter error LED to identify
the component that caused the error.
b. Check the system-error log for information about the
error.
c. If you cannot isolate the failing component by using
the LEDs and the information in the system-error log,
remove one component at a time; and restart the
server after each component is removed.
d. Replace the following components, in the order shown,
restarting the server each time:
v PCI riser cards
v ServeRAID adapter
v Optional network adapter
v (Trained technician only) System board
e. If the failure remains, go to http://www.ibm.com/
systems/support/supportsite.wss/
docdisplay?brandind=5000008&lndocid=SERV-CALL.
2. If the PCI LED and the CONFIG LED are lit, complete the
following steps to correct the problem:
a. Check the microprocessor installed is Intel E5-2690.
b. Remove the high-power (>25 Watt) adapter.
c. Check the system-error logs for information about the
error. Replace any component that is identified in the
error log.
NMI A nonmaskable interrupt has
occurred, or the NMI button was
pressed.
1. Check the system-error log for information about the error.
2. Restart the server.
