Symptom Action
The OVER SPEC LED on the
light path diagnostics panel is
lit, or the Pwr rail A error has
been recorded in the IMM2
event log.
1. Disconnect the server power cords.
2. (Trained technician only) Remove microprocessor if Pwr Rail A was detected.
3. (Trained service technicians only) Replace the system board (see “Removing
the system board” on page 290 and “Installing the system board” on page 292).
4. Reinstall the component; then, restarting the server. If the Pwr rail A error has
been recorded in the IMM2 event log again, the component that you just
reinstalled is defective. Replace the defective component.
v (Trained technician only) Microprocessor 1 (see “Removing a microprocessor
and heat sink” on page 279 and “Installing a microprocessor and heat sink”
on page 282).
5. Replace the power supply if the OVER SPEC LED on the light path diagnostics
panel is still lit.
The OVER SPEC LED on the
light path diagnostics panel is
lit, or the Pwr rail B error has
been recorded in the IMM2
event log.
1. Disconnect the server power cords.
2. (Trained technician only) Remove microprocessor if Pwr Rail B was detected.
3. Restart the server. If the Pwr rail B error has been recorded in the IMM2 event
log again, (trained technician only) replace the system board (see “Removing
the system board” on page 290 and “Installing the system board” on page 292).
4. Reinstall the component; then, restarting the server. If the Pwr Rail B error has
been recorded in the IMM2 event log again, the component that you just
reinstalled is defective. Replace the defective component.
v (Trained technician only) Microprocessor 2 (see “Removing a microprocessor
and heat sink” on page 279 and “Installing a microprocessor and heat sink”
on page 282).
5. Replace the power supply if the OVER SPEC LED on the light path diagnostics
panel is still lit.
