Install 48U Advanced Rack Extension Kit

See this topic to learn how to install 48U Advanced Rack Extension Kit.

Note

  • Each unit of rack extension kit comes with additional capacity for up to two 0U PDUs, or one 0U PDU and one manifold, on each side of the rack.

  • Each rack cabinet supports up to two units of rack extension kit (one to the front and one to the rear side).

  • If there is a plan to install baying kit while only one of the adjacent cabinets will be installed with extension, make sure to install the baying kit first (see Install the baying kit). Then, as preparation for this procedure, remove the two screws from the upper and lower part of the cabinet that will be installed with the extension kit, and jump to Step 2.

  • Required tools
    • One tool with plastic blade/scissors to open the packaging
    • One rubber hammer to align the extension panels with the side of the rack
    • One Screwdriver with No. 3 Phillips bit to tighten the M6 screws (9 in the next bullet point)
    • One Nut-driver with holding hex bit 10 mm to tighten the M6 screws (9 in the next bullet point)
    • One 2.5 mm Hex bit socket to tighten the M4 screws (13 in the next bullet point)
    • One 3 mm Hex bit socket to tighten the M5 screws (PDU/manifold brackets, opening covers on the extension panels)
    • One 4 mm Hex bit socket to tighten the M6 screws (3 and 12 in the next bullet point)
  • The extension kit comes with a miscellaneous bag, which contains the following components:

Procedure

  1. Install fourteen M6 cage nuts to the rack frame with cage nut insertion tool or a flat-blade screwdriver.
    Figure 4. Cage nut installation location

    With cage nut insertion tool
    Figure 5. Installing cage nuts with cage nut insertion tool

    • Insert one edge of the cage nut into the target mounting flange hole, and hook the other edge with the insertion tool through the flange hole.
    • Rotate and pull the tool to force the other nut edge into the flange hole, and thus secure the nut.
    With flat blade screwdriver
    Figure 6. Installing cage nuts with flat blade screwdriver

    • Insert one edge of the cage nut into the target mounting flange hole.
    • Press and compress the other nut edge with a flat-blade screwdriver, and rotate the screwdriver towards the flange hole until the nut edge goes in the hole.
    • Release the screwdriver to secure the nut in the mounting flange hole.
  2. Tighten the fourteen screws to secure the two extension panels to the rack.
    Note
    If baying kit has been installed previously, make sure to remove the two screws from top and bottom of the cabinet first. Then, secure the screws through the panel and the baying kit.
    Figure 7. Installing the extension panels

  3. Align the extension top cover with the screw holes on the extension panels, and secure it with six screws.
    Figure 8. Installing the extension top cover

  4. Depending on the requirements, remove the filler(s) from the extension panels to route cables.
    Figure 9. Removing the filler(s)

    1. Loosen the screws that secure the filler to the extension panel.
    2. Remove the filler.
  5. If there is a plan to install 0U PDU to the extension panel, complete the following steps.
    Depending on the requirements, select the corresponding installation procedures.
    • Bracket with two keyhole slots (up to two PDUs, or one PDU and one manifold)
      Note
      • Below illustration shows the locations for installing the brackets.
        Figure 10. Locations for installing the brackets with two keyhole slots

      • If one or two brackets are installed in the locations indicated in the illustration below, the M6 hex head flange screw must be replaced with an M6 round head flange screw.
        Figure 11. Replacing the screw

        1. Remove the M6 hex head flange screw.
        2. Install the M6 round head flange screw.
      1. Align the bracket with the extension panel, and secure it with four screws.
        Figure 12. Installing the bracket with two keyhole slots

      2. Insert the two PDU pegs into the keyhole slots on the brackets, and push down the PDU to secure it to the brackets. Choose the left or right slot for PDU installation based on the requirements.
        Figure 13. Installing the PDU

        Note
        PDU can be rotated 180 degrees for installation with the input cable at the bottom.
    • L-shaped bracket (up to two PDUs, or one PDU and one manifold)
      Note
      • Below illustration shows the locations for installing the brackets.
        Figure 14. Locations for installing the L-shaped brackets

      • If one or two brackets are installed in the locations indicated in the illustration below, the M6 hex head flange screw must be replaced with an M6 round head flange screw.
        Figure 15. Replacing the screw
