HEAVY EQUIPMENT -- PERSONAL INJURY OR EQUIPMENT DAMAGE MAY RESULT IF MISHANDLED (D006)

Procedure

  1. Verify that the new location meets the necessary service clearances for the storage facility which include any attached racks. Refer to the installation site requirements for the DS8000® in IBM DS8870 Introduction and Planning Guide.
  2. Do you have more than one rack to install?
    • Yes, continue at the next step.
    • No, go to step 4.
  3. You must ensure that each expansion rack is installed to the base rack (Rack-1) that it was originally configured with.
    Note: If expansion racks for two storage facilities are accidentally intermixed, a successful installation will not be possible.
    • Each rack has a small label Callout label 1 with its rack S/N above the left rear door latch. See Figure 1.
    • Each rack has a large label Callout label 2 with its rack number (position in the storage facility) and the S/N of the Rack-1 it must be installed to. The label is to the right of the UEPO switch. See Figure 1.

  4. Move Rack-1 to its permanent location. If installing on a raised floor, position the rack so the rear tailgate, especially the rightmost opening for the mainline power cables, is directly over the floor tile cutouts.
  5. Install the wheel chocks Callout label 1 (located in the ship group) on all four casters. Refer to Figure 2.

  6. Open the front cover.
  7. Open the left rear cover (customer access area).
  8. Open the right rear cover (trained service personnel access area only). Use a 3mm hex wrench to remove the two screws Callout label 1.
    Note: The screws must be reinstalled when the cover is closed to prevent customer access.
