Hotswap v2 to v3 line cards?

    We are planning to setup VSF on a pair of existing 5400R switches, and part of that will be upgrading the line cards to v3. I know line cards are hot swappable but I am unsure if there are any extra considerations when switching to v3. Is it as simple as removing the old card, installing the new one, and moving the cables?

    You can remove and replace a zl module whilst the system is live.

    You can change module type as well, but you will have to remove the module from the config, which will remove all the port configs.

    Command will be similar to:

    remove module 3

    And IIRC, VSF requires V3 modules only, which will require

    no allow-v2-modules

    Thanks for the reply! Would you happen to have some documentation on that or be able to clarify a bit? Would the sequence be something like:

    1) Remove old module

    2) Install new one

    3) Run 'no module a'

    4) Run 'module a type XXXXXX'

    5) Add configuration to module

    This is the process I use:

    1. Backup config and collect all the relevant system info (eg sh int br, sh vlan, sh trunck, etc)
    2. Label and remove cables from the module to be removed
    3. Run 'no module a'
    4. Remove module
    5. Insert new module (automatically detects and adds the new module to the config, all ports in VLAN 1)
    6. Enter the config relevant to the ports in the new module (VLANs, trunks, QOS, ACLs, etc)
    7. Re-connect the cables
    8. Test
