MAP 0240: Wide Processor Node DC Short/Open
002 (continued)
Memory cards
– Replace any damaged components found during inspection.
– Recheck resistance per Step 001 on page 1-120.
Is resistance in the acceptable range?
Yes No
003
– Replace the appropriate component from second table in Step 001 on page 1-120.
– Go to Step 021 on page 1-123 to verify fix.
004
Problem resolved.
– Go to “MAP 0570: End of Call” on page 1-357.
005
Measured resistance is too low.
– Use the following table to continue service based on the cable connector where the short was detected:
006
Problem involves the CPU planar.
– Clip multimeter leads to the connector pins for the voltage that shows resistance out of range.
– Remove memory cards one-at-a-time until all components have been removed or resistance enters
acceptable range.
Did removing memory cards make the short disappear?
Yes No
007
– Replace the CPU planar.
– Go to Step 021 on page 1-123 to verify fix.
008
Problem was in memory card(s).
– Replace the memory card which is causing a short.
– Go to Step 021 on page 1-123 to verify fix.
