MAP 0440: Short in 48 Volts DC Power Distribution
013 (continued)
Is there an obvious problem with the 48 V dc power harness?
Yes No
014
– Replace the 48 V dc power harness.
– Reconnect the processor node or switch assembly and check for a short condition
again.
– Continue at the second bullet (powering on any bulk dc power supplies that are Off)
of Step 012 on page 1-259.
015
– Correct the obvious problem. If necessary, replace the 48 V dc power harness.
– Reconnect the processor node or switch assembly and check for a short condition again.
– Continue back at the second bullet of Step 012 on page 1-259.
016
– Go to Step 009 on page 1-259 and reconnect next cable.
017
Possible short in processor node(s) or switch assemblies.
– Put processor node and switch assembly circuit breakers in On (‘1’) position one at a time, checking the
frame supervisor green LED #2 for an OFF condition, indicating a short condition.
Are you able to power on all processor nodes and switch assemblies without indication of a short
condition?
Yes No
018
– Remove the processor node or switch assembly causing the short condition from the frame.
– Check the 48 V dc power harness inside the processor node or switch assembly for an obvious
problem which might be causing the short condition.
Is there an obvious problem which might be causing the short condition?
Yes No
019
– Replace the node supervisor card or switch power card.
Note: If this is an HiPS 2.0 switch assembly, replace the entire switch assembly to fix
problem.
– Reconnect the processor node or switch assembly and put circuit breaker in the On (‘1’)
position.
– From the control workstation, enable any power supplies that are turned off.
– Go to Step 017.
020
– Fix the obvious problem which might be causing the short condition.
– Reconnect the processor node or switch assembly and put circuit breaker in the On (‘1’) position.
