Troubleshooting
Replacing the RA4000 Controller cache with the same size cache does not
require that you power down the system. If the cache is upgraded, or a different RA4000
Controller is to be reinstalled in the system, you must power down the system.
1. If you will be upgrading the cache or reinstalling a different RA4000
Controller, power down the servers attached to the RA4000, then power
down the RA4000.
2. Remove the Fibre Channel cable and GBIC from the existing RA4000
Controller.
3. Squeeze the front latches 1 and open the two ejector levers 2 securing
the RA4000 Controller.
4. Remove the RA4000 Controller by pulling it straight out of the
chassis 3.
