Diag LED Patterns (R = Red, Y = Yellow, G = Green, l = Off)
Pattern
Error
Suggested Solutions
RRYY
Fatal internal processor error (#IERR).
Restart. If it’s a random event and not due
to hardware, it should not recur.
RYYl
No memory detected.
Insert or reseat the RIMMs.
Reseat the memory expander card.
RYYY
Corrupted memory.
Reseat the memory expander card.
Reseat the RIMMs.
YRll
BIOS is in crisis recovery mode.
Wait until the BIOS recovery operation is
complete (indicated by LED pattern GRll).
Follow the solution steps for the GRll
pattern.
YYRl
3.3v circuitry error.
Reseat I/O cards.
GRll
BIOS recovery complete.
If you have set system switch 2 on the
system board to On, turn it Off and reboot
the system.
GYRl
1.8V power circuitry error.
Reseat the memory expander card.
GGRY
Battery voltage error. Battery may be at
the end of its life.
Reseat the battery.
Replace the battery.
lYRY
12V power circuitry error.
Reseat the I/O cards.
lYRG
2.5 RDRAM power circuitry error.
Reseat the memory expander card.
If the memory expander card has a
separate voltage regulator module, reseat
the module.
