$DEV_NAME $FRU_NAME, has been selected.

To prepare for this service action, perform the following:

- Enable the reserve the Common Storage Module (CSM) function.

  1. Reserve the CSM for maintenance.

  2. Enter a description of the service action (converting a controller tray) .

  3. Select the estimated amount of time of the service action from the pull-down.

  4. Select the Reserve button.

     a) Other users will be alerted that this service action is in progress when they login.

- Important: This procedure is disruptive to the customer.

- Determine the final configuration and the extent of the disruption.

- Ensure that there is no system I/O to the controller tray being converted and any trays connected to it.

  Observe all ESD precautions.

  Removing Power to the Tray(s)

  1. Power supply "A" is located on the left and power supply "B" is located on the right when viewing the CSM from the rear.

     a) View the power supply location illustration.

  2. Press the power switches on the power supplies to the Off positions on the controller tray to be coverted.

  3. If the controller tray being converted will be moved, remove the power cables from each power supply.

  4. For any expansion trays that were connected to the controller tray being converted press the power switches on the power supplies to the Off position as well.

  5. The expansion trays that were connected to the controller tray being converted will need to be power cycled with the controller they will now be connected to.

  Replacing the Controller Cards with I/O Modules (IOM)

  1. Controller card "A" is located on the left and controller card "B" is located on the right when viewing the CSM from the rear.

     a) View the controller/IOM card location illustration.

  2. Disconnect the host cables and expansion interface cables (if any) from the first controller card. Ensure that all cables are labeled before removing them.

  3. To remove the controller card, push down on the black spring loaded latch in the middle of the controller card that secures the two removal levers in place. While pushing down on the latch, pull the lever handles outward to remove the controller card.

     a) View the controller card/IOM removal illustration.

  4. Unpack the I/O module and save all of the packing materials to return the controller card in. Use care when handling either the I/O module or the controller card.

  5. Record the MAC address for the new I/O module from the white label on the I/O module cover before inserting it in the tray. This information will be needed in the Restoring Power to the Tray section.

     a) View the MAC address label location.

  6. Insert the new I/O module until it connects with the midplane connector. Use care not to bend any pins.

  7. Push in the latch handles to secure the new I/O module with the connector being sure that the latch holds the handles in place.

  8. Repeat steps 2 through 7 for replacing the remaining controller card.

  Relocating the Tray (if necessary)

     a) View removing the rear mounting screws illustration.

  2. From the front of the cabinet, remove the end caps from each side of the tray.

     a) View the removing end caps illustration.

  3. Remove the four screws that secure the tray to the cabinet frame.

     a) View removing the front mounting screws illustration.

  4. Slide the tray out of the cabinet using two people. Use care the tray is heavy.

     a) View removing the tray illustration.

  5. Carefully lift and slide the converted tray into the new location.

  6. Secure the tray to the front of the cabinet frame with the four screws.

  7. Replace the end caps to cover the front mounting screws.

  8. From the rear of the cabinet, insert and tighten the four rear mounting screws.

  Restoring Power to the Tray(s)

  Note: Before turning on power to the tray make sure that the Dynamic Host Configuration Protocol (DHCP) server has been set up with the corresponding MAC address for the new I/O modules.

  1. If the converted tray was moved connect the power cables to the power supplies.

  2. Press the power switches on the power supplies to the On positions for the converted/expansion tray(s) first and then the controller tray to On last.

  3. Repeat step two if any expansion trays from the original configuration were connected to a different controller tray.

  4. It will take several minutes for all of the trays to become completely ready. The trays will be ready when only the Green LEDs are on solid.
