SUN 6540 Array with failed controller battery

Can someone point me to a procedure detailing the replacement of a failed battery in a SUN 6540 controller.

Or describe the procedure.

Thanks

  1. open a call with oracle
  2. brew a strong coffee
  3. wait for a oracle field engineer to do the work

or use the CAM software with the integrated "servie advisor" to get a step-by-step procedure...
