Step 1521-13
Check that the wall outlet is properly wired and is providing the correct voltage.
Did you find a problem?
NO Go to “MAP 1548: Processor Subsystem Problem Isolation” on page 113.
YES Correct the problem. Go to ″MAP 0410: Repair Checkout″ in the RS/6000 Eserver pSeries
Diagnostic Information for Multiple Bus Systems.
Step 1521-14
Because the Model 6C3 and Model 6E3 accommodate redundant power supplies, it is not necessary to
power down the system when replacing a power supply.
The power supplies are symmetrical. Replacement starts with the unit closest to the system wall of the
system drawer (power supply 1). For instructions on replacing a power supply, refer to “Power Supply” on
page 348.
Notes:
1. Always service first the power supply whose green LED, located on the front of the power supplies, is
out.
2. Before removing a power supply, be sure the redundant power supply is operational by observing the
green LED. The green LED must be on solid.
Replace the following FRUs in order:
1. Power supply #1 (primary)
2. Power supply #2 (redundant)
Perform error log analysis.
Do you receive an SRN indicating a voltage sensor out of range?
NO The last FRU exchanged is defective. Go to ″MAP 0410: Repair Checkout″ in the RS/6000
Eserver pSeries Diagnostic Information for Multiple Bus Systems.
YES Reinstall the original FRU.
Repeat the FRU replacement steps until a defective FRU is identified or all the FRUs have been
exchanged.
If the symptom did not change and all FRUs have been exchanged, go to “Step 1521-15.”
If the symptom changed, check for loose cards, cables, and obvious problems. If you do not find a
problem, go to the “Quick Entry MAP” on page 55 and follow the instructions for the new
symptom.
Step 1521-15
The problem is within the system unit hardware or with the line voltage/wiring.
Shut down the system, and remove the power cable from the system unit.
Exchange the following FRUs in the order listed.
1. VRM at U0.1-P1-V1
2. VRM at U0.1-P1-V2
3. VRM at U0.1-P1-V3
4. System backplane
