Extending all racks to full height

Use extension hardware to extend all racks to full height. Populate the extension section as required.

1. You are installing rack extension hardware. Insert wheel chocks (if available) or temporarily lower the stabilizer feet to prevent the rack from moving.
2. 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.

   

3. 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 3.a above) only while actively lifting the cover, and engage the safety pins (step 3.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.

      

      

4. Install and secure the extension panels. The guide pins on each panel point down. See Figure 4 and Figure 5. The extension panels and the screws that are used to secure them are described in Table 1.
   Note: The rear panels are larger and have a notch for the top cover struts that is closer to the edge of the panel, compared to the front panels.
   1. Install the front left extension panel. Secure to frame with two screws at front and rear of panel. Do not tighten the screws at this time.
   2. Install the rear left extension panel. Secure to frame with two screws at front and rear of panel. Do not tighten the screws at this time.
   3. Install the rear right extension panel. Secure to frame with two screws at front and rear of panel. Do not tighten the screws at this time.
   4. Install the front right extension panel. Secure to frame with two screws at front and rear of panel. Do not tighten the screws at this time.

   

   Note: In Figure 5, screws used to secure panels might be different from screws that are shown in the diagram. See Table 1.

   

5. Lower the top cover to the top of the extension panels, and secure to the panels. The screws that are used to secure the top cover are described in Table 1. 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 that are used for the remainder of this section of the procedure are described in Table 2.
6. Install the storage enclosure rails.
   Note: There are up to three sets of rails to install in the extension section, depending on model.
   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 985, 986, 988, 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.
      Notes:

      • The result for all-flash models is nut clips that are installed on the 1st, 3rd, 9th, 13th, and 15th holes from the top of the extension panel. Refer to Table 1.
      • Leave the nut clips installed in the top hole of the base rack EIA rails, just below 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.

enclosure)

7. Are you installing Rack-1 of an all-flash model 985, 986, or 988?
   • Yes. Go to step 8.
   • No. Go to step 10.
8. You are installing an all-flash Rack-1. Move the cable brackets (cable retention bars), with cables attached, to their operating locations.
   Note:

   • Rack-1 of a model 988 or model 986 all-flash has two cable brackets at the top of the storage enclosure rails at EIA location 40.
   • Rack-1 of a model 985 all-flash has only one bracket at that location.
   1. Move the upper cable bracket (if provided) from its location above the storage enclosure rails at EIA location 40 to the top of EIA location 46.
      1. Secure the bracket to the nut clips you installed at the 1st hole at the top of the extension panel (above the storage enclosure rails at EIA location 46).
      2. The cable labels that are associated with this bracket are shown in Table 3.
   2. Move the lower cable bracket from its location at the top of the storage enclosure rails at EIA location 40 to the top of EIA location 42
      1. Secure the bar to the nut clips you installed at the 13th hole down from the top of the extension panel (above the storage enclosure rails at EIA location 42).
      2. The cable labels that are associated with this bracket are shown in Table 3.

      Table 3. Microbay and storage enclosure cable labels

      Model	Power cables (if attached) are labeled for connection to		SAS cables (if attached) are labeled for connection to

      985 all-flash	none	M06-C1, C2	none	M06, F05, F06
      986 all-flash	M06-C1, C2	M08-C1, C2	M06, F05, F06	M08, F07, F08
      988	M02-C1, C2	M04-C1, C2	M02, F01, F02	M04, F03, F04

9. For all-flash model 986 or 988, install the microbay tray (shipped separately, with the storage enclosures) at the rear of the storage enclosure rails at EIA locations 43-44.
   Notes:

   • You will always install a microbay tray at this location in all-flash model 988.
   • You will install a microbay tray at this location in all-flash model 986 if you have flash enclosures to install in EIA locations 43-46 (F05 and F06).
   • You will not install a microbay tray at this location in other models.
   • Microbays are installed in this tray when flash enclosures are present at EIA locations 43-46
     • F01 and F02 for model 988
     • F05 and F06 for model 986
     See Enclosure locations topic Figure 6 and Figure 7.
   1. Remove the microbays (if present) from the tray before installing.
      • Important: microbays must be installed in their original locations from manufacturing, as designated on SAS and PCIe cable labels.
      • Leave SAS and PCIe cables attached to the microbays.
      • Note which microbay is C1 and which is C2. The cable labels show these locations.
      • Press the release tabs  1  toward the center of each microbay. See Figure 10.
      • Slide each microbay back. Release the service latches  2  and  3 , as needed, and remove the microbay.
   2. At the rear of the rack, install the microbay tray.
      Note: See Figure 10. The microbays are installed into the rear end of the tray.

      • Note the flange that extends outward on either side of the microbay tray, about 7 cm from the front end of the tray.
      • Lift the tray so the side flange is above the rear mounting flange of the storage enclosure rail. This fits the tray between the rail you are fastening it to, and the rail above it.
      • Slide the tray in until the tray flange passes the rail flange.
      • Lower the tray and slide into place against the stop pins in the storage enclosure rails.
      • Secure with screws to the bottom hole of each storage enclosure rail.
10. At the front of the rack, install the storage enclosures.
    Notes:

    • This includes both high-performance flash enclosures and FC-AL attached storage enclosures.
    • Storage enclosure components must be removed to meet single-person lifting limits. All components must be labeled before you remove them, and must be reinstalled in their original locations from manufacturing.
    • For location of storage enclosures in racks, see Table 4, Table 5, and Enclosure locations.
    1. Label and remove all drives from each storage enclosure.
    2. Label and remove the FCICs or ESMs from the rear of each storage enclosure.
    3. Label and remove the power supplies from the rear of each storage enclosure.
    4. Install each storage enclosure in its correct location. At the front of the rack, secure to frame at the lower left and lower right of each enclosure with the screws provided.
    5. Reinstall the power supplies, FCICs or ESMs, and drives in their original location in each storage enclosure.
    6. Install the decorative bezels (packaged with the enclosure) at the left front of the enclosure.
11. At the front of the rack, install storage enclosure fillers in any empty storage enclosure locations.
12. At the rear of the rack, install the cable brackets on the rails in extension section storage enclosure locations.
    • G01 and G03 for standard systems. See Table 4.
    • F01 and F03 for all-flash model 88E Rack-2. See Table 5.

    Note: This step does not apply to model 85E Rack-5, or to all-flash racks other than model 88E Rack-2.
    1. Slide the cable bracket  1  onto the bottom of the rail.
    2. Ensure the spring-loaded latches  2  located on either side of the bracket, are secure.
