    Installing the Mounting Hardware

    Install the mounting hardware on the rack before installing the switch. The QFX10008 comes with a four-piece set of mounting brackets that supports the chassis in the rack.

    Note: Two-post installation racks are not supported.

    The four mounting bracket pieces are:

    • 1 left front mounting bracket. The bracket is labeled “LEFT FRONT” on the side of the bracket that faces the interior of the rack, near the holes for attaching the bracket to the rack.
    • 1 right front mounting bracket. The bracket is labeled “RIGHT FRONT” on the side of the bracket that faces the interior of the rack, near the holes for attaching the bracket to the rack.
    • 2 rear mounting brackets. These brackets are labeled “REAR” on the side of the bracket that faces the interior of the rack, near the holes for attaching the bracket to the rack. The rear brackets are interchangeable; you can use either of the rear brackets with the right or left front-mounting bracket.

    Ensure that you have the following parts and tools available to install the mounting brackets:

    • A Phillips (+) screwdriver, number 1, 2, or 3, depending on the size of your rack-mounting screws
    • A Phillips (+) screwdriver, number 2, to install the screws that connect the rear-mounting and front-mounting brackets
    • 16 mounting screws appropriate for your rack to attach the 4 mounting bracket pieces to the rack

    When you install the mounting brackets, the adjustable portion of the brackets overlap. Use the overlap area to adjust the total bracket length to fit any of the four standard rack sizes: 19 in. (483 mm), 23.62 in. (600 mm), 30 in. (762 mm), or 31.5 in. (800 mm).

    To install the mounting brackets in a four-post rack:

    1. Remove the mounting brackets from the accessory box.
    2. Decide where to place the chassis in the rack. If the rack is empty, mount the switch in the lowest possible location. See Rack-Mounting Requirements.
    3. Position the left front adjustable mounting bracket at the desired position in the left side of the rack and line up its front screw holes with the holes in the rack. Use four mounting screws appropriate for your rack to attach the left front bracket to the rack.
    4. Position one of the rear brackets at the left rear of the rack on the same level as the left front bracket, so that the rear bracket overlaps with the left front bracket. The screw holes for connecting the front and rear brackets should overlap. Use four mounting screws appropriate for your rack to attach the rear bracket to the rack.
    5. Connect left front and rear brackets (see Figure 5):
      1. Insert six of the screws provided with the mounting brackets into the overlapping bracket holes.
      2. Hand-tighten the screws fully (to 12–16 in.-lb torque) using a number 2 Phillips screwdriver.

    6. Position the right front adjustable mounting bracket at the desired position in the right side of the rack opposite the installed left front bracket, so that it is on the same rack level as the left bracket. If the right and left front brackets are not on the same level, the chassis will rest at an angle in the rack instead of resting flat and level. Line up the right bracket's front screw holes with the holes in the rack. Use four mounting screws appropriate for your rack to attach the right front bracket to the rack.
    7. Position the other rear bracket at the right rear of the rack on the same level as the right front bracket, so that the rear bracket overlaps with the right front bracket. The screw holes for connecting the front and rear brackets should overlap. Use four mounting screws appropriate for your rack to attach the rear bracket to the rack.
    8. Connect the right front and rear brackets (see Figure 5):
      1. Insert six of the screws provided with the mounting brackets into the overlapping bracket holes.
      2. Hand-tighten the screws fully (to 12–16 in.-lb torque) using a number 2 Phillips screwdriver.
