Sounds like the hardware is dead.

 - Could you verify the current value of the config-register with the rommon set command ?

 M.

rommon 5 >set

That is the wrong value. 

Do this in ROMMON: 

confreg 0x2102

And then reboot the line card.

I did, but when I restart and look at the set command, the value does not change

 

 

rommon 1 >confreg 0x2102
usage: confreg
rommon 2 >set

set ConfigReg=0x2102

NOTE:  Above command is case sensitive. 

If it boots correctly, I want to see the config.  There could be something in the configuration forcing the switch to change config-registry to 0x8000 series.

invalid command

 

rommon 1 >set ?
Set commands:

set interface use 'set interface help' for more info on how
to set IpAddr and other networking parameters

set ip use 'set ip help' for more info on how
to set Gateway variable for default route

To set an arbitrary Rom Monitor variable to some value
please type 'variable=value' directly (without set).
rommon 2 >set Configreg=0x2102

No, the command was invalid because the next line provided an example of the syntax. 

Please try: 

confreg 2102

negative commands
