Replacing a Power Filter Unit
Up to two -48 VDC Power Filter Unit (PFU) assemblies can be installed in the ASR 5000 chassis. Two PFUs
provide load-balancing and redundancy. The PFUs are located in the lower-rear of the chassis.
Although a single PFU can provide power for a fully loaded chassis, it is strongly recommended that two
PFUs always remain installed for load-balancing and redundancy.
Caution
During installation, maintenance, and/or removal, wear a grounding wrist strap to avoid ESD damage to
the components. Failure to do so could result in damage to sensitive electronic components and potentially
void your warranty.
Caution
This chapter provides instructions for replacing a PFU in the event of failure. It includes the following
sections:
•
Determining that a PFU has Failed, page 197
•
Removing the Failed PFU, page 198
•
Installing the Replacement PFU, page 200
•
What to do with the Failed PFU, page 203
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.
