Hi - (pardon the ignorance)
I believe this is a config issue. Since I basically unpacked everything mounted the chassis and inserted the cards. In an essence no config.
Anyhow, I notice amber light on the sup engine in slot 4.
No matter what I do, the redundant supervisor will not come active. It does not show up when you run "show inventory". I know the switch thinks it is present, because it shows both supervisors' TenGig interfaces. I had pulled the redundant Sup out hot, then plug it back in. There are log messages that show it being removed and show it being reinserted, but it does not show up in show inv.
I then swap the 2 Sups. The one that was the active in slot 3 previously became the active in slot 4, and the redundant Sup still would not show up. This at least proved that all of the slots are good. When I plugged the console into the redundant Sup, I get the prompt "rommon>" instead of "switch>".
I don't know if any of this is normal behavior. I did see on the switch that the Sup shows up in show inv. I dont possess deep knowledge of dual sup but perhaps redundancy sso needs to be configured?
The switch is new the chassis is 4507 E
the sups are WS-X45-SUP6-E
The rest of the slots are filled with the following: WS-X4648-RJ45V+E
and (1) WS-X4306-GB
Sounds like the 2nd sup is not booting , console in and issue "boot bootflash: command and see if the sup will boot . Once up verify the config register and software versions are the same.
