what is the output of showstatus ?

Hi DukeNuke2

output of showstatus below;

XSCF> showstatus
*   MBU_A Status:Degraded;

first thing I would try is to get a service password from oracle (a SR has to be opened to get one) and after that use the clearfault command to reset the error.
also check that all cables to the XSCF are in the right place (serial cable on serial port; network cable on network port).

Hi DukeNuke2

Thanks for the info.
The procedure that finally solved it was as follows;

To clear service led: Power off the platform, put key in service position,power on platform.


Appreciate your rapid responses


Cheers
