Uninstall the ACX7020 Router

Learn how to power off the router and remove it from the rack or cabinet.

Power Off an ACX7020 Router

Before you power off an ACX7020 router:

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

  • Ensure that you do not need to forward traffic through the router.

Ensure that you have the following parts and tools available to power off the router:

  • An ESD grounding strap (not provided)

  • An external management device such as a PC (not provided)

  • An appropriate cable to connect the external management device to the console port (not provided)

To power off your ACX7020 router:

  1. Connect to the router using one of the following methods:
  2. Shut down Junos OS from the external management device by issuing the request system halt operational mode CLI command. This command shuts down the router gracefully and preserves the system state information. A message appears on the console, confirming that the operating system has halted.

    You see the following output (or something similar, depending on the hardware being shut down) after entering the command:

  3. 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.
  4. Disconnect power to the router by performing one of the following tasks:

    • AC power supply—If the AC power source outlet has a power switch, set it to the off (O) position. If the AC power source outlet does not have a power switch, gently pull out the power cord plug connected to the power source outlet.

    • DC power supply—Switch the circuit breaker on the panel board that services the DC circuit to the off position.

  5. Remove the power source cable from the power supply faceplate:

    • AC power supply—Remove the power cord from the power supply faceplate by detaching the power cord retainer and gently pulling out the socket end of the power cord connected to the power supply faceplate.

    • DC power supply—Remove the screws securing the ring lugs attached to the power source cables to the power supply module (PSM) using the screwdriver, and remove the power source cables from the PSM. Replace the screws on the terminals and tighten them.

  6. Remove the power source cable from the power supply faceplate.

    Remove the screws securing the ring lugs attached to the power source cables to the PSM using the screwdriver, and remove the power source cables from the PSM. Replace the screws on the terminals and tighten them.

  7. Disconnect all cables from the router before removing it from the rack or cabinet.

Remove an ACX7020 Router from a Rack or Cabinet

Before you remove the ACX7020 router from its rack, ensure that you have a Phillips (+) screwdriver, number 2 or number 3, depending on the size of your rack-mount screws.

If you need to relocate an installed ACX7020 router, use the procedure described in this topic.

Note:

When you remove multiple devices from a rack, remove the device at the top of the rack first and proceed to remove the rest of the devices from top to bottom.

  • Ensure that the rack is stable and secured to the building.

  • Ensure that there is enough space to place the removed router in its new location and along the path to the new location.

  • Use the appropriate power-off sequence to safely power off the device. See Power Off an ACX7020 Router.

  • Disconnect the power cords.

  • Ensure that you have disconnected any cables or wires attached to the router ports.

To remove an ACX7020 router from a rack or cabinet:

  1. Have one person support the weight of the router while another person uses the screwdriver to remove the front mounting screws that attach the rack mounting brackets to the rack or cabinet.
  2. Slowly slide the router out of the rack, with the mounting brackets attached to its sides.
  3. Place the removed screws in a labeled bag. You will need them when you reinstall the chassis.
  4. Transport the router to your new location.
