IBM® xSeries 360: User’s Reference
On CPU One of the microprocessors has
failed, or a microprocessor is installed
in the wrong connector. 1. Open the top cover and check the
microprocessor error LEDs on the
system 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” on
page 79 for information about the
correct order for installing
microprocessors. 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 remains, replace
the microprocessor.
If the problem remains, call for
service.
On DASD A hot-swap hard disk drive has failed. 1. If the amber hard disk drive status
LED on one of the hot-swap hard
disk drives is on, replace the
drive.
2. Check the error log for additional
information. If the error log
indicates a temperature problem
and the fans are working
correctly, check for air flow
blockage.
On Non Redund The server is operating in
nonredundant power mode. Two or
more power supplies are installed in
the server, and either one power
supply has failed or the server has
reached a condition in which it is no
longer operating in redundant mode. If a power supply has failed, replace
the failing power supply. If not, add a
power supply to ensure redundancy.
On Out of Spec The server is drawing more power
than the power supplies are rated for. Either add a power supply or remove
a device from the server.
On PS3 The third power supply has failed. Replace the third power supply.
On PS2 The second power supply has failed. Replace the second power supply.
On PS1 The first power supply has failed. Replace the first power supply.
Off None The Light Path Diagnostics feature
has not detected a system error. None
