GYRY
-12V power circuitry failure.
This circuit is only used by a few
serial devices and PCI cards.
1.
Reseat all the I/O cards and serial
device connections.
2.
Try removing the I/O cards and
serial devices one at a time to see
which card or device may be
causing the error. Replace any
device or card that appears to
cause the error.
3.
Replace the power supply as
described in “System Memory” on
page 159.
4.
Replace the system board as
described in “System Board” on
page 186.
GYRG
Processor core (VCC_CORE) power
circuit error.
1.
If you have recently added a
processor, reseat the processor.
2.
If you have recently added a
processor, remove it. If the error
goes away or changes, replace it as
described in “Processor” on page
177.
3.
Replace the system board as
described in “System Board” on
page 186.
GYR
●
1.8V power circuitry error.
1.
Reseat the memory expander card.
2.
Replace the memory expander
card.
3.
Replace the system board as
described in “System Board” on
page 186.
