Table 1. Light path diagnostics (continued)
LED Cause Action
PCIA An error occurred on PCI bus
A. An adapter in PCI slot 1 or
2, or the processor board
caused the error. 1. Check the error log for additional
information.
2. If you cannot correct the problem from
the information in the error log, try to
determine the failing adapter by removing
one adapter at a time from PCI bus A
(PCI slots 1–2) and restarting the server
after each adapter is removed.
PCIB An error occurred on PCI bus
B. An adapter in PCI slot 3, 4,
5, or 6 or the processor board
caused the error.
1.
Check the error log for additional
information.
2.
If you cannot correct the problem from
the information in the error log, try to
determine the failing adapter by removing
one adapter at a time from PCI bus B
(PCI slots 3–6) and restarting the server
after each adapter is removed.
PCIC An error occurred on PCI bus
C. An error on the processor
or I/O board caused the
problem. Check the error log for additional
information. If the error log indicates a
problem with the integrated SCSI controller,
the Ethernet controller or video controller, see
“Starting the diagnostic programs” on
page 14.
DASD A hot-swap hard disk drive
has failed on SCSI channel B. 1. If the TEMP LED is also on, take the
actions listed for that LED.
2. If the amber status LED on one of the
hot-swap hard disk drives is on, replace
the drive.
MEM A memory error occurred. 1. Check the DIMM error LEDs on the
memory board.
2. Replace the DIMM indicated by the lit
DIMM error LEDs.
CPU One of the microprocessors
has failed or a microprocessor
is installed in the wrong
connector. 1. Check the microprocessor error LEDs on
the memory board. If a microprocessor
error LED is on for a microprocessor
connector that has a terminator card
installed instead of a microprocessor, the
microprocessors are not installed in the
correct order. See “Installing a
microprocessor kit” on page 57 for
information about the correct order for
installing microprocessors and VRMs.
Otherwise, continue with the next step.
2. Turn off the server, reseat the
microprocessor indicated by the lit
microprocessor error LED, and restart the
server.
3. If the problem persists, replace the
microprocessor.
VRM One of the voltage regulator
modules on the processor
board has failed.
1.
Check the VRM error LEDs on the
processor board.
2.
Turn off the server, reseat the VRM
indicated by the lit VRM error LED, and
restart the server.
3. If the problem persists, replace the VRM.
