The outputs of "show platform" and "show facility-alarm status" list one or more power supply modules in a failed state, even though the power supplies are working as intended: Router#show platform Slot Type State Insert time (ago) --------- ------------------- --------------------- ----------------- P0 ASR1000-PWR-AC ps, fail 1d6h P1 ASR1000-PWR-AC ps, fail 1d6h Router#show facility-alarm status System Totals Critical: 2 Major: 0 Minor: 0 Source Time Severity Description [Index] ------ ------ -------- ------------------- Power Supply Module 0 Jan 01 2000 00:00:00 CRITICAL Power Supply Failure [0] Power Supply Module 1 Jan 01 2000 00:00:00 CRITICAL Power Supply Failure [0] The output of "show environment all" and other outputs will show the power supply operating as expected: Router#show environment all Sensor List: Environmental Monitoring Sensor Location State Reading PEM Iout P1 Normal 7 A PEM Vout P1 Normal 12 V DC PEM Vin P1 Normal 120 V AC PEM Iout P0 Normal 7 A PEM Vout P0 Normal 12 V DC PEM Vin P0 Normal 120 V AC After PSU is on fail condition the command "show platform software trace message chassis-manager rp active" should present errors of pfu_status_mask being 0 and would help confirm if this bug is a match: 02/03 19:18:19.428 [cmand]: [1870]: (note): pfu_status_mask after 0
The condition can trigger when there is a loss of input power on a power supply, or if the power supply module is unseated, then reseated in the chassis.
Reloading the router can clear the false positive status conditions, but a software upgrade will be needed to keep them from triggering again.
the bug could only happen on ASR1K modular chassis platforms. ISR4K platforms are not affected by the bug.
