Contacting Customer Support and Returning the Chassis or Components

How to Return a Hardware Component to Juniper Networks, Inc.

If a hardware component fails, please contact Juniper Networks, Inc. to obtain a Return Material Authorization (RMA) number. This number is used to track the returned material at the factory and to return repaired or new components to the customer as needed.


Do not return any component to Juniper Networks, Inc. unless you have first obtained an RMA number. Juniper Networks, Inc. reserves the right to refuse shipments that do not have an RMA. Refused shipments are returned to the customer by collect freight.

Guidelines for Packing Hardware Components for Shipment

To pack and ship individual components:

  • When you return components, make sure that they are adequately protected with packing materials and packed so that the pieces are prevented from moving around inside the carton.

  • Use the original shipping materials if they are available.

  • Place individual components in antistatic bags.

  • Write the RMA number on the exterior of the box to ensure proper tracking.


Do not stack any of the hardware components.

Packing the ACX Series Router for Shipment

To pack the router for shipment:

  1. Retrieve the shipping box and packing materials in which the router was originally shipped. If you do not have these materials, contact your Juniper Networks representative about approved packaging materials.
  2. On the console or other management device connected to the Routing Engine, enter CLI operational mode and issue the following command to shut down the router software.

    Wait until a message appears on the console confirming that the operating system has halted.

    For more information about the command, see the CLI Explorer.

  3. Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an ESD grounding point.
  4. Shut down power to the router by pressing the AC input switch or DC circuit breaker for all power supplies to the off (O) position.
  5. Disconnect power from the router.
  6. Remove the cables that connect to all external devices.
  7. Remove all field replaceable units (FRUs) from the router.
  8. Remove the router from the rack. One person should grasp the router while a second person unscrews and removes the mounting screws from the rack. One lifter can then move the router to the shipping container.
  9. Place the router in the shipping container.
  10. Cover the router with an ESD bag and place the packing foam on top of and around the router.
  11. Replace the accessory box on top of the packing foam.
  12. Securely tape the box closed.
  13. Write the RMA number on the exterior of the box to ensure proper tracking.
