Determining That A Pfu Has Failed - Cisco ASR 5000 Series Installation Manual

▀ Determining that a PFU has Failed

Determining that a PFU has Failed
The chassis can use one of several mechanisms to indicate a PFU failure. The first indicator is when the POWER LED
on the PFU is off. If the LED is off and a starPowerState SNMP trap is generated with a value of Failed (2), the PFU
must be replaced.
If you do not receive this trap, try the following suggestions to diagnose the cause:
 Verify that the power switch is in the ON position.
 Verify that the RTN and -VDC lugs are attached according to the instructions provided in this document.
 Verify that the ground lug is attached according to the instructions provided in this document.
 Verify that the power source is on and is supplying the correct voltage and sufficient current.
 Check the cables from the power source to the rack for continuity.
 If a fuse panel is installed between the Power Distribution Frame (PDF) and the chassis, verify that the fuses are
intact.
 If a fuse panel is installed between the PDF and the chassis, check the cables from the fuse panel to the chassis
for continuity.
