– Detach cable N00-SB-P102 or S00-SB-P102 at supervisor bus card, then check for a short
between pin 1 and 2 on component U102 (large power transistor) on supervisor card.
Do you detect a short condition between U101 pins 1 and 2?
Yes No
025
– Replace supervisor bus card.
– Go to Step 029 to verify fix.
026
– Replace cable N00-NS-P101 or S00-SP-P101.
– Go to Step 029 to verify fix.
027
– Go to Step 028.
028
– Refer to "FRU Removals and Replacements" in
IBM RS/6000 SP: Maintenance Information, Volume 3,
Locations and Service Procedures to replace the appropriate part from the following list:
Processor node supervisor card
HiPS 2.0 switch assembly
HiPS 3.0 switch supervisor card
HiPS-LC8 switch supervisor card
SPS switch supervisor card
SPS-8 switch supervisor card
– Go to Step 029.
029
Component causing a short condition was replaced.
– Make sure all cables are reconnected in processor node(s) switch assemblies and at SEPBU.
– Check frame supervisor LEDs and SEPBU rear panel LED.
Are any LEDs lit?
Yes No
030
Another short exists in the 12 V dc distribution.
– Go to Step 013 on page 1-269.
031
Problem resolved.
– Go to Step 084 on page 1-279.
