Replacing standalone Sup720 in c6509 VSS

[asemeniuc23]

Hello,

I have to replace standalone sup 720 in c6509 chassis. This sup act as a stanby engine in VSS configuration.

I am going to follow next steps:

1. Disconnect cables from standby sup

2. Remove supervisor (hot swap)

3. Remove CompactFlash (bootdisk sp) from old one install into the new one

4. Insert the new sup into the chassis

5. Copy config from bootdisk to startup-config

6. Power down

7. Connect all cables and power on.

Is it safety to replace the supervisor without powering down the entire chassis? Any suggestions/corrections to my plan.

Thanks in advance!

I use only one supervisor per chassis.
