Unpack and Mount an ACX7100-48L Router

Unpack an ACX7100-48L Router

The ACX7100-48L router chassis is a rigid sheet-metal structure that houses the hardware components. An ACX7100-48L router is shipped in a cardboard carton, secured with foam packing material. The carton also contains an accessory box and quick start instructions.


ACX7100-48L routers are maximally protected inside the shipping carton. Do not unpack the router until you are ready to begin installation.

To unpack an ACX7100-48L router:

  1. Move the shipping carton to a staging area as close to the installation site as possible, where you have enough room to remove the system components.
  2. Position the carton so that the arrows are pointing up.
  3. Open the top flaps on the shipping carton.
  4. Remove the accessory box, and verify the contents against the inventory included in the box.
  5. Pull out the packing material that is holding the router in place.
  6. Verify the chassis components that you received.
  7. Save the shipping carton and packing materials in case you need to move or ship the router later.

Register Products—Mandatory to Validate SLAs

Register all new Juniper Networks hardware products and changes to an existing installed product using the Juniper Networks website. Registering products and changes to products activates your hardware replacement service-level agreements (SLAs).


Register product serial numbers on the Juniper Networks website. Update the installation base data if any installation base data is added or changed or if the installation base is moved. Juniper Networks will not be held accountable for customers not meeting the hardware replacement service-level agreement (SLA) for products that do not have registered serial numbers or accurate installation base data.

Mount an ACX7100-48L Router in a Rack

You can mount an ACX7100-48L router on a rack by using the mounting kit provided with the device.

Before You Begin Rack Installation

Before you begin mounting an ACX7100-48L router in the rack:

  1. Ensure that you understand how to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.
  2. Verify that the site meets the requirements described in Site Preparation Checklist for ACX7100-48L Routers.
  3. Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the building structure.
  4. Read General Site Guidelines, with particular attention to Chassis and Component Lifting Guidelines.
  5. Remove the router from the shipping carton. See Unpack an ACX7100-48L Router.
  6. Ensure that you have the following parts and tools available to mount the router in a rack:
    • ESD grounding strap (not provided)

    • One pair of front-mounting rails (provided)

    • Screws to secure the mounting rails to the chassis (provided)

    • Phillips(+) screwdriver, number 1 and number 2, for the mounting screws (not provided)

    • Two power cords with plugs appropriate for your geographical location (provided)

    • RJ-45 cable and RJ-45 to DB-9 serial port adapter (provided)

    • Management host, such as a PC laptop, with a serial port (not provided)


If you are mounting multiple units on a rack, mount the heaviest unit at the bottom of the rack and mount the other units from the bottom of the rack to the top in decreasing order of the weight of the units.

Install an ACX7100-48L Router in a Rack

To install the router in a four-post rack:

  1. Position the router in front of the rack.
  2. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to a site ESD point.
  3. Align the holes in the front-mounting rails with the holes on the side of the chassis (see Figure 1).
    Figure 1: Install the Mounting Rails on an ACX7100-48L RouterInstall the Mounting Rails on an ACX7100-48L Router
  4. Using a Phillips (+) number 1 screwdriver, secure the mounting rails to the chassis using the mounting screws.
  5. With one person on each side, hold on to the bottom of the chassis, and carefully lift the chassis so that the mounting rails are aligned with the rack rails.
  6. Carefully slide the chassis with the rails attached on to the rack rails (see Figure 2).

  7. Install mounting screws into each of the front-mounting bracket holes aligned with the rack, starting from the bottom, and tighten the screws. Figure 3 shows the router fully secured to the front rails of the four-post rack.

  8. On the rear of the chassis, slide the rear-mounting blades on either side of the chassis until the rear-mounting brackets at the end of the blades contact the rack rails (see Figure 4).

    The rear-mounting blades on each side of the chassis are movable. You can adjust the length of the blades according to the depth of the rack.

  9. Install mounting screws into each of the rear-mounting bracket holes aligned with the rack, starting from the bottom, and secure them tightly. Apply 5.0 to 5.5 lb-in of torque to the screws.
  10. Visually inspect the alignment of the chassis.

    If you’ve installed the chassis properly in the rack, all the mounting screws on one side of the rack are aligned with the mounting screws on the opposite side, and the router is level. Figure 5 shows the router fully secured and installed in a four-post rack.
