Troubleshooting
None needed.
Verify that each circuit breaker is in the ON
position.
Verify that the RTN and -48VDC lugs are
attached properly to the posts on the upper
rear of the chassis.
Verify that the ground lug is attached
properly.
Use a voltmeter to verify that the power
distribution panel is supplying the correct
voltage and sufficient current to the
terminals at the rear of the PFU.
Check the cables from the power source to
the rack for continuity.
If a power distribution panel (PDP) is
installed between the power distribution
frame (PDF) and the chassis, verify that its
circuit breakers are set to ON.
If a PDP is installed between the PDF and
the chassis, check the cables from the PDP
to the chassis for continuity.
If all of the above suggestions have been
verified, then it is likely that the PFU is not
functional. Please contact your service
representative.
