Hi All,
I wish to replace the SUP720 engine on my 6509-E. The environment where this device is hosted is susceptible to hardware failures during powercycles hence I wish if I could replace only the SUP with the current IOS and not have to reload the chasis. Below steps I believe would acheive those results , need suggestions its good to go.
- Remove flash from the new SUP and place it in the currently installed SUP (to be replaced) in the chasis.
- Copy the current IOS and Startup config on the external Disk.
- Remove the disk from the existing SUP and place it back onto the new SUP.
- Remove the existing SUP from the Chasis and insert the new SUP.
- Break the boot sequence and let it go into ROMMON.
- From there boot the switch from the IOS copied on external flash Disk0.
- When the switch boots with the desired IOS delete the existing startup config file from NVRAM.
- Copy the startup-config ( earlier copied from the old SUP) from disk 0 to NVRAM.
- Copy startup config to running config.
- Copy the IOS onto sup-bootflash.
- Change the bootvar to point to the sup-bootflash
- Configure the secondary bootvar as the IOS in disk0.
This will restore the switch back to its original config with the original IOS, without needing a reboot for the chasis and manually having to configure the switch via the console.
Thanks in Advance
Umesh
