Power supplies (including, but not limited to: NXA-PAC-1200W-PE/PI) may shut/noshut abnormally without causing any impact on the working on the switches
Nexus model is N9K-C93360YC-FX2 The issue is random and no generic conditions exist Power supplies include, but are not limited to NXA-PAC-1200W-PE/PI
The Power supplies seem to recover without any manual intervention
We have an ongoing issue where we see some power supplies on pair of nexus switches Shut/noshut abnormally without causing any impact on the working on the switches 2023 Sep 8 01:51:54 %$ VDC-1 %$ %PLATFORM-2-PS_ABSENT: Power supply 1 is absent/shutdown, ps-redundancy might be affected 2023 Sep 8 01:51:54. %$ VDC-1 %$ %PLATFORM-2-PS_RED_MODE_CHG: Power supply operational redundancy mode changed to non-redundant 2023 Sep 8 01:51:55 %$ VDC-1 %$ %PLATFORM-2-PS_PWR_INPUT_MISSING: Power supply 1 present but all AC/DC inputs are not connected, power redundancy might be affected 2023 Sep 8 01:51:55 %$ VDC-1 %$ %PLATFORM-2-PS_RED_MODE_RESTORED: Power redundancy operational mode changed to configured mode 2023 Sep 8 01:51:56 %$ VDC-1 %$ %PLATFORM-2-PS_CAPACITY_CHANGE: Power supply PS1 changed its capacity. possibly due to On/Off or power cable removal/insertion 2023 Sep 8 21:09:15 %$ VDC-1 %$ %PLATFORM-2-PS_ABSENT: Power supply 1 is absent/shutdown, ps-redundancy might be affected 2023 Sep 8 21:09:15 %$ VDC-1 %$ %PLATFORM-2-PS_RED_MODE_CHG: Power supply operational redundancy mode changed to non-redundant 2023 Sep 8 21:09:16 %$ VDC-1 %$ %PLATFORM-2-PS_PWR_INPUT_MISSING: Power supply 1 present but all AC/DC inputs are not connected, power redundancy might be affected 2023 Sep 8 21:09:16 %$ VDC-1 %$ %PLATFORM-2-PS_RED_MODE_RESTORED: Power redundancy operational mode changed to configured mode 2023 Sep 8 21:09:17. %$ VDC-1 %$ %PLATFORM-2-PS_CAPACITY_CHANGE: Power supply PS1 changed its capacity. possibly due to On/Off or power cable removal/insertion `show environment` Fan: --------------------------------------------------------------------------- Fan Model Hw Direction Status --------------------------------------------------------------------------- Fan1(sys_fan1) NXA-FAN-160CFM-PE -- back-to-front Ok Fan2(sys_fan2) NXA-FAN-160CFM-PE -- back-to-front Ok Fan3(sys_fan3) NXA-FAN-160CFM-PE -- back-to-front Ok Fan_in_PS1 -- -- back-to-front Ok Fan_in_PS2 -- -- back-to-front Ok Fan Zone Speed: Zone 1: 0xb3 Fan Air Filter : NotSupported Power Supply: Voltage: 12 Volts Power Actual Actual Total Supply Model Output Input Capacity Status (Watts ) (Watts ) (Watts ) ------- ---------- --------------- ------ ---------- -------------------- 1 NXA-PAC-1200W-PE 170 W 176 W 1200 W Ok 2 NXA-PAC-1200W-PE 186 W 190 W 1200 W Ok Power Usage Summary: -------------------- Power Supply redundancy mode (configured) PS-Redundant Power Supply redundancy mode (operational) PS-Redundant Total Power Capacity (based on configured mode) 1200.00 W Total Grid-A (first half of PS slots) Power Capacity 1200.00 W Total Grid-B (second half of PS slots) Power Capacity 1200.00 W Total Power of all Inputs (cumulative) 2400.00 W Total Power Output (actual draw) 356.00 W Total Power Input (actual draw) 366.00 W Total Power Allocated (budget) N/A Total Power Available for additional modules N/A Temperature: -------------------------------------------------------------------- Module Sensor MajorThresh MinorThres CurTemp Status (Celsius) (Celsius) (Celsius) -------------------------------------------------------------------- 1 FRONT 80 70 27 Ok 1 BACK 70 42 25 Ok 1 CPU 90 80 34 Ok 1 Heavenly 110 100 47 Ok
