Extending the rack to full height and attaching to the storage facility

About this task

The following lists the sequence to extend the expansion rack (as needed) and attach it to the storage facility.
  • Use the extension hardware to extend the expansion rack to full height (for models with rack extension hardware).
  • Use the merge kit (sometimes called a marriage kit) to fasten the expansion rack to the storage facility.
  • Continue with the installation.
Refer to the following tables for an overview of the parts that are used in various stages of installation.

Procedure

  1. Check now to see if each expansion rack you are installing has EMI seals on the left side of each rack. Record your results.
    Note: The EMI seals are 4 mm wide metallic strips that are attached to the side of the rack near the front, rear, top, and bottom edges.
    • _____ Expansion racks have EMI seals.
    • _____ Expansion racks do not have EMI seals.
  2. Are you installing an expansion rack with rack extension hardware?
  3. You are installing rack extension hardware. Insert wheel chocks (if available) or temporarily lower the stabilizer feet to prevent the rack from moving.
  4. At the top of the rack, remove four screws from each side of the top cover. See Figure 1.
    Notes:
    • The top cover is secured with eight long M10 hex head screws. The extension kit includes a 12 mm deep socket for use with the screws. Store the socket in the document enclosure at the rear of the machine after use.
    • The top cover is raised in stages to three or more different stop points at both the front and rear.

    When the top cover is at the final stop, the extension panels are installed and secured to the frame. After the panels are secure, the top cover is lowered and secured to the extension panels.

    Attention: Apply pressure up and down to ensure that the stop latches engage and hold the top cover at each stop.

  5. Raise the top cover to full extension. See Figure 2 and Figure 3.
    1. Release the four safety locking pins, one at each corner of the rack, by pulling out each pin and rotating 1/4 turn.
    2. Lift the rear of the top cover to the first stop. Ensure that the safety latches are engaged.
      Note: Use a light up-and-down force on the top cover to confirm that the latches are engaged.
      Attention: If the latches do not automatically engage or the top cover slips back down, release the safety pins (step 4.a above) only while actively lifting the cover, and engage the safety pins (step 4.g below) at each stop
    3. Lift the front of the top cover to the first stop. Ensure that the safety latches are engaged.
    4. Lift the rear of the top cover to the next stop. Ensure that the safety latches are engaged.
    5. Lift the front of the top cover to the next stop. Ensure that the safety latches are engaged.
    6. Repeat steps d and e until the top cover is fully extended.
    7. Engage the four safety locking pins by rotating each pin about 1/4 turn until it snaps into the frame. Ensure that the pins are fully seated.

  7. Lower the top cover to the top of the extension panels, and secure to the panels. The screws that used to secure the top cover are described in Table 5. They were removed from the top cover at the beginning of this procedure.
    1. Release the four safety locking pins, one at each corner of the rack.
    2. Carefully push down on the rear of the top cover until it rests on top of the rear extension panels.
    3. Carefully push down on the front of the top cover until it rests on top of the front extension panels.
    4. Check that the four safety locking pins have latched. Latch manually, if required.
    5. Insert four screws into each side of top panel, leaving them loose. Screw position is at front and rear of each extension panel.
    6. Tighten the screws that were installed in step 5 to secure the extension panels to the frame. Alternate between the left and right sides of the frame, in the order shown in Figure 7.
    7. Tighten the screws that were installed in step 6 to secure the top panel to the extension panels. Alternate between the left and right sides of the top panel, in the order shown in Figure 7. See Figure 6 and Figure 7.

    Note: the fasteners used for the remainder of this section of the procedure are described in Table 6.
  8. Install the storage enclosure rails.
    1. Install nut clips, if not already present, on the left rear and right rear EIA rails of the extension panels.
      Note: Nut clips are spaced every six holes, following the existing pattern in the storage enclosure section of the rack. The result is nut clips that are installed on the 3rd, 9th, and 15th holes from the top of the extension panel. Refer to Table 1.
    2. For all-flash models 85E, 86E, and 88E install additional nut clips, in top hole and 13th hole from top, on the left rear and right rear EIA rails of the extension panels.
    3. Insert the left and right side rails from the front of the rack, making sure that the rails align with the EIA rail holes front and rear.
    4. At the rear of the rack, secure both the left and right rails with the screws provided.

Important: In the steps that follow, you install storage hardware (storage enclosures, high-performance flash enclosures, or microbays) in the extension section of the rack. Each of these components was packaged separately from the rack you are installing. Take time to identify the locations of these components.

Look for a label that is fastened to the top of the enclosure or microbay. An identical label is found on the side of the package that contains the enclosure or microbay. This label contains the rack identification, rack serial number, and component location.


Example:
  
A-BOX (rack identification - in this case, A-BOX represents Rack-1)
HGD40 (serial number of Rack-1)
F02   (component location - in this case, F02, which is a high-performance flash enclosure)
