Cause
En af CPU'erne var offline, hvilket fik kontakten til at slukke.
Resolution
Permanent løsning:
- Hvis alle 6 CPU'er ikke er online, skal du udskifte switchen og sørge for, at den nye switch kører på NX-OS v8.4(1a) eller nyere.
- Hvis alle 6 CPU'er er online, skal du opgradere firmwaren til NX-OS v8.4 (1a) eller nyere for at undgå gentagelse.
