(Continued) The power supplies are using
more power than their maximum
rating. If the 12 V channel E error LED is lit, complete the following
steps:
1. Turn off the server and disconnect the power from the
server.
2. Remove the PCI riser card from PCI riser connector 2 and
the microprocessor in socket 2.
3. Restart the server to see whether the problem remains.
4. Reinstall each device that you removed in step 2 one at a
time, starting the server each time, to isolate the failing
device.
5. Replace any failing device.
6. (Trained service technician only) Replace the system
board.
If the 12 V AUX channel error LED is lit, complete the

server.
2. Remove all PCI Express and PCI-X cards, all PCI riser
cards, the operator information panel, and the Ethernet
adapter (if installed).
Note: The server will not power-on when the
microprocessor in socket 1 or 2 is not installed in the
server. (Trained service technician only) Toggle the switch
block (SW4), bit 3 to allow the server to power-on. See
“System-board switches and jumpers” on page 39 for the
location of the SW4 switch block on the system board.
3. Restart the server to see whether the problem remains.
4. Reinstall each device that was removed in step 2 one at a
time, starting the server each time, to isolate the failing
device.
5. Replace any failing device.
6. (Trained service technician only) Replace the system
board.
LOG An error occurred. Check the IMM system event log and the system-error log for
information about the error. Replace any components that are
identified in the error logs.
LINK Reserved.
