We supplied Catalyst 6509 our customer site recently.

but We got the problem, the problem is that the supervisor didn't come up, still remained rommon mode. the log like below:

rommon 1 >

Although We had configured bootvar sup-bootdisk or disk0: , the supervisor remained with rommon mode. In order to boot, We should enter the command "boot disk0:"

In my opinion, It's fault sup-720-3B, but I would like to know Why it is

Thank in advance any comment~!

Do you have the right IOS loaded on the box?

Do you have the boot variable set up?

boot system flash sup-bootdisk:

You may have a bad flash card. If you have good working flash card put it in this sup and reload the box and see what happens.

the bootvar configuration has no problem, When I use that config to other C6509, It has no problem to working.

It seems to be a Battery issue located in Supervisor 720-3B board.
