Recovery CatOS Cisco WS-X4014

Come recuperare una Supervisor Cisco avviando da CatOS su server tftp.
Ci serve:

1. PC con TFTP server installato (quello della Sun o qualsiasi altra cosa va bene!);
   
2. Supervisor non compatibile con chassis causa CatOS;
3. Una CatOS compatibile (nell'esempio sottostante si aggiorna da una cat4000.6-3-5 ad una cat4000-k8.8-4-9-GLX);
4. cavo console e cavo eth;

Ecco di seguito i principali comandi:

! configuro l'interfaccia ethernet a cui collegherò il server TFTP

riavviando dovrebbe partire la CatOS prescelta come primaria!!!
