Install the SRX4120

This topic guides you through the steps to install the SRX4120 on four-post racks.

You can mount the SRX4120 on a four-post rack or cabinet. Use the rack mount kit shipped with the device.

Complete these prerequisites before you mount the device:

  • Prepare the site for installation as described in Site Guidelines and Requirements.

  • Ensure that the site has adequate clearance for both airflow and hardware maintenance.

    Figure 1: Clearance Requirements for SRX4120 Technical diagram of a Juniper Networks device with dimensions: width 18.6 in, height 17.3 in, depth 19.9 in. Requires 24 in clearance on both sides. Labels indicate network ports on left and field replaceable units on right.

  • Unpack the device as described in Unpack the SRX4120.

Note:

Ensure that you support the rear of the chassis throughout the process of mounting the appliance on the rack.
CAUTION:

A qualified technician must verify that the rack or cabinet is strong enough to support the device's weight before mounting the device. Have the technician also verify that the rack or cabinet has adequate support at the installation site.

If you are installing more than one device on a rack or in a cabinet, install the first device at the bottom of the rack.

Mount your Device by Using the JNP-4P-TL-1RU-RMK Rack Mount Kit on a Square Hole 4-Post Rack

Ensure that you have the following tools and parts available:

  • An ESD grounding strap—not provided.

  • A pair of side mounting brackets that attach to the chassis—provided with the rack mount kit.

  • A pair of front and rear mounting rails that attach to the rack posts—provided with the rack mount kit.

To mount the device on a four-post rack:

  1. Review the General Safety Guidelines and Warnings.
  2. Wrap and fasten one end of the electrostatic discharge (ESD) cable grounding strap around your bare wrist, and connect the other end to a site ESD point.
  3. To attach the side mounting brackets to the chassis, align the keyholes on the mounting brackets over the shoulder screws on the chassis. Slide the mounting brackets toward the rear of the chassis so that the shoulder screws get locked in place.

  4. Assemble the mounting rails by sliding the rear mounting rails into the front rails.
    Figure 3: Assemble the Mounting Rails Assemble the Mounting Rails
  5. Install the mounting rails on the rack:
    1. Align the guide blocks of the rear mounting rails with the rear-post holes. Pull the rear mounting rails toward the front of the rack to lock the rails in place. You will hear a distinct click sound when the latch locks into the corresponding rack holes.

Mount your Device by Using the JNP-4P-TL-1RU-RMK Rack Mount Kit on a Threaded-Hole 4-Post Rack

Ensure that you have the following tools and parts available:

  • An ESD grounding strap—not provided.

  • A Phillips (+) screwdriver, number 2—not provided.

  • Eight screws to attach the mounting rails to the rack posts—not provided.

  • A pair of side mounting brackets that attach to the chassis—provided with the rack mount kit.

  • A pair of mounting front and rear rails that attach to the rack posts—provided with the rack mount kit.

To mount the device on a four-post rack with threaded holes:

  1. Review the General Safety Guidelines and Warnings.
  2. Wrap and fasten one end of the electrostatic discharge (ESD) cable grounding strap around your bare wrist, and connect the other end to a site ESD point.
  3. To attach the side mounting brackets to the chassis, align the keyholes on the mounting brackets over the shoulder screws on the chassis. Slide the mounting brackets toward the rear of the chassis so that the shoulder screws get locked in place.
