IBM iSeries 820 Hardware Problem Analysis And Isolation

b. Use a multimeter to measure the ac voltage at the customer’s ac power outlet.
Is
the ac voltage from 200 V ac to 240 V ac or from 100 V ac to 127 V ac?
v Yes: Continue with the next step.
v No: Inform the customer that the ac voltage at the power outlet is not correct.
This
ends the procedure.
12. Is circuit breaker CB1 on the PCC of the failing frame set to the | (on) position?
v No: Set circuit breaker CB1 on the PCC to the | (on) position. Continue with the next step.
v Yes: Exchange the following FRUs one at a time:
– PCC
– Frame control panel
– Frame control panel cable
Note: See the Remove and replace procedures page, or the FC 504x Problem Analysis and
Repair and Parts information (SY44-4934-00), or the Migrated Expansion Tower Problem Analysis,
Repair and Parts manual on the V5R1 Supplemental Manuals web site , depending on the
secondary frame you are working on.
This ends the procedure.
13.
Power on the system. Does CB1 remain in the | (on) position?
v Yes: Continue with the next step.
v No: Exchange the power control compartment.
Note: See the Remove and replace procedures topic, or the FC 504x Problem Analysis and Repair
and Parts information (SY44-4934-00), or the Migrated Expansion Tower Problem Analysis, Repair
and Parts manual on the V5R1 Supplemental Manuals web site , depending on the secondary
frame you are working on.
This
ends the procedure.
14.
Does the failing frame become powered on?
v No: Continue with the next step.
v Yes: This ends the procedure.
15.
Is the Attention light blinking?

16.
The Attention light is on. This may be a normal condition. Does the Attention light remain on for more
than 1 minute?
v No: This ends the procedure.
v Yes: Exchange the following FRUs one at a time:
– PCC
– AC module
– Frame control panel
– SPCN frame-to-frame cable
Note: See the Remove and replace procedures topic, or the FC 504x Problem Analysis and Repair
and Parts information (SY44-4934-00), or the Migrated Expansion Tower Problem Analysis, Repair
and Parts manual on the V5R1 Supplemental Manuals web site , depending on the secondary
frame you are working on.
This
ends the procedure.
