●
YRY
12V power circuitry error.
1.
Reseat PCI and AGP I/O cards.
2.
Try removing the I/O cards one at a
time, restarting the Workstation
each time. If it appears the error is
being caused by one card, replace
the card.
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.
●
YRG
2.5 V RDRAM power circuitry error.
1.
Reseat the memory expander card.
2.
If the memory expander card has a
separate voltage regulator module,
reseat or replace the voltage
regulator module.
3.
Replace the RIMMs or CRIMMs as
described in “System Memory” on
page 159.
4.
Replace the memory expander
card.
