b. Refer to the procedure for removing the disk drives and remove the disk drives. Label each disk drive as to its exact location so that it can be re-installed once the chassis is installed in the cabinet. 2. [ ] Manually, or using the portable lift (shown below), align the chassis rails with the inner rails attached to the cabinet. If using a lift, lock the casters into place. Note: If the chassis is being installed manually without a lift, it generally requires three people to install. Two people to hold the chassis in place at the correct height, and one person to align and manage the slides. 3. [ ] Manually slide the inner rail over the chassis rail 2-3 inches to line them up. Figure 1 Sliding the shelf chassis into the rails Note: You may need to release sagging tension on the shelf by pulling the lift arms and tray up slightly. Page 17 of 33

CAUTION: Make sure to leave the lift under the chassis until the shelf is safely balanced and secured within the cabinet. 9.

Re-install the Fan modules. c. Slide the shelf into the cabinet. d. From the rear of the cabinet, re-install the power supplies and the LCCs into the shelf. Inserting and securing the top cover and chassis How the chassis is inserted and secured into the cabinet depends upon which configuration of securing mechanism is installed on the shelf. The first configuration has orange self-locking latches above the enclosure latch handles. The second configuration has captive shoulder screws which attach the chassis to the cabinet. 1.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
