## Chapter 2. Replacing the Origin Vault Controller Board

This chapter consists of the following sections:

- “Preparing the Origin Vault Expansion Option for Component Replacement”

- “Replacing the Power Button Plate on the Side-Hinged Door”

- “Replacing the Controller Board Assembly”

This procedure requires:

- #2 Phillips screwdriver

- Flat-blade screwdriver

- Grounding strap (included in the upgrade kit)

## Preparing the Origin Vault Expansion Option for Component Replacement

Follow the steps in this section to prepare the Origin Vault rackmounted enclosure or standalone tower for component replacement.

1. Have ready the replacement components:

   - Controller board assembly

   - For a rackmounted Origin Vault option, front panel

2. Make sure that no users are using the data stored in the Origin Vault expansion option. Check the status LEDs for each drive to make sure they are not active. If appropriate, follow proper shutdown procedures for the host to which the Origin Vault is cabled.

3. Turn off the power button at the front; the LED goes dark.

4. Turn off the master power switch at the rear of the Origin Vault expansion option.

5. Detach the power cable from the Origin Vault expansion option.

6. If the Origin Vault is padlocked, unlock it; see “Locking the Origin Vault Expansion Option” in Chapter 3 of the Origin Vault Owner's Guide.

7. For the tower, or for a rackmounted Origin Vault option with the bottom-opening door, open the door and remove the crossbar, as shown in Figure 2-1. Set the crossbar aside.

   Figure 2-1. Removing the Crossbar (Origin Vault Standalone Tower)

   For a rackmounted Origin Vault option with the side-opening door, remove the faceplate:

   - Remove the door by pulling it off the hinges (see Figure 2-2). Lay the door on a work surface.

   - Pry off the end cap at the right end of the faceplate (see Figure 2-2).

     Figure 2-2. Removing the Faceplate: Origin2000 Rack

   - Pry the faceplate out of the brackets at the sides of the rack; you might need a flat-blade screwdriver for this operation. See Figure 2-3.

## Replacing the Power Button Plate on the Side-Hinged Door

The upgrade kit includes a plastic power button plate that accommodates the redesigned power switch on the controller board.

With the door on a work surface, insert a flat-blade screwdriver at the top edge of the original plastic power button plate to pry it off, as shown in Figure 2-4. Discard this assembly; it is not factory-returnable.

Attach the new power button plate; it snaps on.

## Replacing the Controller Board Assembly

To remove the controller board assembly, follow these steps:

1. Ground yourself with a wrist strap: attach the clip to the metal frame of the chassis.

2. Unscrew the two screws that secure the controller board carrier to the front of the chassis, as shown in Figure 2-5.

   Figure 2-5. Detaching the System Controller Carrier From the Front of the Chassis

3. Pull out the controller board assembly. You can save it or discard it; it is not factory-returnable.

4. If desired, remove disk modules 5 and 6 (or blanking plates if no disks are installed) so that you can see the socket in the backplane into which the controller board's edge connector must go. If necessary, label the disks so that they are reinserted into the correct drive bays.

5. Insert the new controller board assembly into its bay. If necessary, guide the board's edge connector into the socket. The assembly installs in one direction only.

   | Caution: Grasp the sides of the board only; do not touch the edge connector.

   When the edge connector is fully seated in the socket, the carrier should be flush with the front of the chassis.

6. Screw in the two screws that secure the controller board carrier to the front of the chassis, as shown in Figure 2-5.

7. If you removed disk modules (or blanking plates), replace them in their drive bays.

8. For an Origin Vault standalone tower, replace the crossbar and close the door.

   If the Origin Vault option has a side-hinged door:

   - Reattach the faceplate by plugging it into the holes in the U-shaped mounting ears.

   - Reattach the door and end cap.

9. Reattach the power cable. Power on the Origin Vault expansion option by turning on the master power switch at the rear and then pushing the power button at the front; the LED illuminates. If appropriate, restart the host to which the Origin Vault expansion option is cabled.
