Fast Track to Rack Installation and Power

This procedure guides you through the steps to install the ACX7020 router in a rack and connect it to power.

Install an ACX7020 Router in a Rack

You can install a Juniper Networks® ACX7020 Cloud Metro router into a 19-inch, 21-inch, or 23-inch two-post rack or a cabinet. We’ll walk you through the steps to install an AC-powered ACX7020 router in a 19-inch two-post rack.

Before you install, review the following:

To mount an ACX7020 router on two posts of a rack:

  1. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the device.
  2. Align the holes in the front-mounting brackets with the holes on the side of the chassis.
  3. Using the screwdriver, secure the mounting brackets to the chassis using the mounting screws.
  4. Lift the router and position it in the rack. Line up the top and bottom holes in each mounting bracket with the holes in each rack rail, making sure the router is level.
  5. Secure the chassis to the rack using the rack-mount screws (not provided). First tighten the screws at the bottom and then the screws at the top.
  6. Check to see that the mounting screws on each side of the rack are aligned and the router is level.

Connect to Power

To connect the ACX7020 router to AC power, perform the following steps:

Connect Earth Ground to ACX7020 Routers

To ground the ACX7020 router:

  1. Verify that a licensed electrician has attached the cable lug that is provided with the router to the grounding cable.
  2. Ensure that all grounding surfaces are clean and brought to a bright finish before you make grounding connections.
  3. Connect the grounding cable to a proper earth ground.
  4. Place the grounding cable lug over the two-hole protective grounding terminal on the front panel of the chassis.
  5. Secure the grounding cable lug to the chassis grounding points using two M5 x 10 mm grounding screws (provided).
  6. Dress the grounding cable and verify that it does not touch or block access to router components and that it does not drape where people could trip over it.

Connect AC Power to ACX7020 Routers

Ensure that you have a power cord appropriate for your geographical location available to connect AC power to the router.

Before you begin connecting AC power to the router:

  • Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).

  • Ensure that you have connected the router chassis to earth ground.

    CAUTION:

    Before you connect power to the router, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the router (for example, by causing a short circuit).

    To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the chassis to earth ground before you connect it to power. Under all circumstances, use the protective grounding terminal on the router chassis to connect to the earth ground. The router gains additional grounding when you plug the power supply module (PSM) in the router to a grounded AC power outlet by using the AC power cord appropriate for your geographical location.

To connect AC power to an ACX7020 router:

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to the ESD point on the chassis.
  2. Power off the AC input appliance inlet on the source power supply.
  3. Connect the power cord to the power source outlet.
    Note:

    You must use a dedicated external circuit breaker for each PSM. We recommend that you use a dedicated customer-site circuit breaker rated for 16A , 250 VAC or as required by the local code.
  4. Press the small tab on the power cord retainer strip to loosen the loop. Slide the loop until you have enough space to insert the power cord coupler into the inlet.
  5. Insert the power cord coupler firmly into the inlet.
  6. Slide the loop toward the PSM until it is snug against the base of the coupler.
  7. Press the tab on the loop and draw out the loop into a tight circle.
  8. Route the power cord appropriately. Verify that the power cord does not block the air exhaust and access to router components, or drape where people could trip over it.
  9. Power on the source power supply.
