4. Remove all four BKMF modules installed in the controller.
5. Loosen the blue right and left screws on the lever of the controller, and
then open the lever.
6. With the lever opened completely, hold the controller with both hands,
and then pull it gently and remove it.
Keep the controller straight to avoid jostling the components above and
below it.
Next steps
• Install the backup module (BKMF) in the new controller.
• Install the cache memory on the new controller.
• Install the cache flash memory on the new controller.
• Use the maintenance utility to restore (unblock) the controller.
Note: If the POWER, READY, WARNING, and ALARM LEDs on the front of the
CBLM/CBLH go off after removing the controller, check the status of the
storage system in the Maintenance Utility window, and then continue the
replacement work. After restoring the controller (described later), confirm
that the LED goes on.
