CiscoCCIEPro,

The router boots up and OK light is ON.
I connect thru console and get the
Router> prompt.
When I type
Router>enable
I get the following message
Router>no password set

I am unable to go to Privilege mode; the router only works in
executive mode.

I tried to go into Rommon by pressing Break key during start-up
but router is not responding to key sequences (Beak, Cntl Break,
Cntrl, F6, Break) as advised by Router documentation.

Braek sequence and console setup works fine when accessing
other 2500 routers.

Your expert advise would be greatly appreciated.
