- What is the fail error (content). You also need to show what leads to rommon mode. You can for instance post screenshot at power on, or console output.

Is this part of active/standby or VSS ? if this is standalone. can you provide whole console logs to understand what is wrong ?

A quick tip is You can do dir and see bootflash has an image so you can boot from ROMMON.

example :

boot bootflash:image.bin

or SUP-T has USB facility you can boot from USB also.

Hi!

Do you know how the switch ended up in ROMMON mode?

Did you face an unexpected reload during normal operation?
Or were you performing a Software Upgrade?

I had an issue with a Cat6k lately that unexpectedly rebooted during normal operation and ended up in ROMMON mode.
But by just issueing ">boot bootflash:<image>.bin" while being connected via serial connection brought the Switch back up and everything worked perfectly fine again.

Do you have any see any error messages during boot while being connected with a console cable?

Best regards
Julian

Console into the supervisor card and reboot.
Post the entire boot-up process.
NOTE: Sup2T has an external CF slot which can be used to force the supervisor card to boot from.
