|Affected Product ID
||Nexus 9500 EoR 3000W Power Supply Failure|
A 3KW DC power supply hardware component failure results in the loss of power output. This power supply is used in 4-slot, 8-slot, and 16-slot Nexus 9500 modular chassis.
Due to a firmware defect, improper handling of certain internal conditions leads to a component failure. As a result, the power supply does not provide DC output. This is reported as “shutdown” in NX-OS.
After the power supply encounters the component failure, the systems flags “shutdown” with the
show environment command.
Cisco recommends that the affected power supply with the old firmware Versions 4.0/4.05 be replaced.
