Se vi trovate nella situazione in cui all'accensione di uno switch Nexus N9K (nel mio caso è un C93180YC-FX) non dovesse partire (status led arancione lampeggiante eppoi tutto spento...) e quando ci colleghiamo in consolle lo switch si presenta cosi:

loader >

per farlo partire basta digitare i seguenti comandi:

 

loader > dir
