MAP 0210: Wide Processor Node Environment
008 (continued)
Are all measured resistances in the acceptable range?
Yes No
009
– Leaving cable where resistance was measured in Step 008 on page 1-99 disconnected, discon-
nect other end(s) of cables from all devices.
– The following list shows cable connections:
Cable (short detected)
N00-PC-P16A: CPU planar J16
N00-PC-P13A: CPU planar J13, J14
N00-PC-P40A: I/O planar J40, J41
N00-PC-P45: DASD P3, DASD P4
N00-PC-P65: DASD P1, DASD P2
– When the cable is entirely disconnected, check for short between voltage and GND pins per table
from Step 008 on page 1-99.
Does disconnected cable show a short condition?
Yes No
010
– Reconnect cable at locations shown in Step 009.
– Go to “MAP 0240: Wide Processor Node dc Short/Open” on page 1-120.
011
– Replace cable.
– Reconnect all cables inside the processor node.
– Remove processor node from service position.
– Reconnect all cables at rear of the processor node.
– Put circuit breaker at front of processor node in On (‘1’) position.
– Go to “MAP 0570: End of Call” on page 1-357.
012
– Replace the components listed in the table below, one at a time:
Priority Component
1 Node power card
2 Wide node supervisor card
3 Cable N00-SV-P102
4 Call next level of support
– Reconnect all cables inside processor node.
– Remove processor node from service position.
– Reconnect all cables at rear of the processor node.
– Put circuit breaker at front of processor node in On (‘1’) position.
– Wait 20 seconds, then check Environmental (Yellow) LED for flashing condition.
