Installing the Mounting Hardware for a QFX10000

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

  • A Phillips (+) screwdriver, number 1, 2, or 3, depending on the size of your rack screws

  • A Phillips (+) screwdriver, number 2, to install the screws that connect the rear and base brackets

  • 12 Phillips flat-head screws (provided)

  • 14 mounting screws appropriate for your rack to attach the mounting hardware to the rack (not provided)

The switch can be installed in a four-post rack or in an open-frame rack. Install the mounting hardware on the rack before installing the switch.

To mount the chassis on a four-post rack, you must first install the mounting hardware in the rack. QFX10008 and QFX10016 switches come with a four-piece set of mounting brackets that support the chassis in the rack. This rack mount kit, EX-MOD-RMK-4POST, can be ordered as a spare. However, if you prefer a solid-shelf design for the rack, JNP-MOD-RMK-4PST is also available by separate order.

Note:

Two-post installation racks are not supported.

The main pieces of the rack mount kit are:

  • One left base 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.

  • One right base 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.

  • Two rear 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 base bracket.

When you install the base and rear 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 hardware in a four-post rack:

  1. Remove the mounting brackets from the rack mount kit 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 QFX10000 Rack Requirements.
  3. Position the left base 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 base 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 base bracket, so that the rear bracket overlaps with the left base bracket. The screw holes for connecting the base and rear brackets should overlap. Use four mounting screws appropriate for your rack to attach the rear bracket to the rack.
  5. Connect left base bracket and rear brackets (see Figure 1):
    1. Insert six of the flat-head 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 base bracket at the desired position in the right side of the rack opposite the installed left base bracket, so that it is on the same rack level as the left base bracket. If the right and left base 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 base bracket's front screw holes with the holes in the rack. Use four mounting screws appropriate for your rack to attach the right base bracket to front of the rack.
  7. Position the other rear bracket at the right rear of the rack on the same level as the right base bracket, so that the rear bracket overlaps with the right base bracket. The screw holes for connecting the base 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 base and rear brackets (see Figure 1):
    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.
