PWR (Power Filter 1 breaker off or voltage low) PWR (Power
Filter 2 breaker off or voltage low)
Either the voltage level of the external DC supply is low or the breaker switch has been
turned off. This alarm is raised if there is no voltage going to the breaker feed or the
voltage is below the threshold (33-35V +/- 1.5V). This could be due to the breaker being
shut off, or due to a problem with the power feed to the breaker card.

Service affecting? No
Applicability PF
Corrective Action
At the end of each step wait to see if the fault clears. If not, continue with the next step.
...................................................................................................................................................................................................
1
Check the breakers for the alarmed shelf and verify that they are ON.
...................................................................................................................................................................................................
2
Using a DC voltmeter, measure the power going to the shelf and verify that it is within
the accepted limits for proper operation (-48 to -52 volts).
If... Then...
the EC reports that a particular PF is faulted, replace the PF.
NOTE: If you do not have a redundant power
filter configuration, this step will be service
affecting.
the EC does report that a particular PF is
faulted,
continue with Step 3.
