||Nexus 5596UP/600x: Silent reload with i2code cause 0x0800 or 0x2|
A particular component failure in N55-PAC-1100W and N55-PAC-1100W-B power supply units (PSUs) can cause the entire 5596UP or Nexus 600x switch to reload.
All N55-PAC-1100W power supplies with a Part Number 341-0415-01 or 341-0415-02 are impacted. N55-PAC-1100W power supply with Part Number 341-0415-03 are not impacted.
All N55-PAC-1100W-B power supplies with a Part Number 341-0461-01 or 341-0461-02 are impacted. N55-PAC-1100W-B power supply with Part Number 341-0461-03 are not impacted.
Note: The previously published impacted Serial Number (S/N) range of "POG1746XXXX and below" still applies if the power supply Part Number is not 341-0415-03 or 341-0461-03. However, it is recommended that impacted PSUs be identified by Part Number instead of S/N, as detailed in the preceding paragraphs.
The most common reason for the system reset is loss of power to the switch. Make sure the switch has dual power supplies connected to different power distribution units (PDUs) and power to the switch is stable.
This bug is seen on switches with redundant power supplies powered up and when one of the power supplies goes bad, which triggers the entire switch to reload.
A single PSU failure in a Nexus 5596UP or Nexus 600x switch might cause the entire system to reboot.
