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.
